==History==

===The road to the CLS: 1972–1999===
[[Image:CSRF Grasshopper.jpg|thumb|left|250px|The [[monochromator]] from the first CSRF beamline, now a museum piece at the CLS]]
[[Image:SAL LINAC.jpg|thumb|left|250px|The SAL LINAC, seen at the CLS in 2011]]

Canadian interest in [[synchrotron radiation]] dates from 1972, when Bill McGowan of the [[University of Western Ontario]] (UWO) organised a workshop on its uses. At that time there were no users of synchrotron radiation in Canada. In 1973 McGowan submitted an unsuccessful proposal to the [[National Research Council (Canada)|National Research Council]] (NRC) for a feasibility study on a possible synchrotron lightsource in Canada. In 1975 a proposal to build a dedicated synchrotron lightsource in Canada was submitted to NRC. This was also unsuccessful. In 1977 [[G. Michael Bancroft|Mike Bancroft]], also of UWO, submitted a proposal to NRC to build a Canadian [[beamline]], as the [[Canadian Synchrotron Radiation Facility]] (CSRF), at the existing [[Synchrotron Radiation Center]] at the [[University of Wisconsin-Madison]], USA, and in 1978 newly created [[Natural Sciences and Engineering Research Council|NSERC]] awarded capital funding. CSRF, owned and operated by NRC, grew from the initial beamline to a total of three by 1998.

A further push towards a Canadian synchrotron light source started in 1990 with formation of the Canadian Institute for Synchrotron Radiation (CISR), initiated by Bruce Bigham of Atomic Energy of Canada Limited ([[AECL]]). AECL and [[TRIUMF]] showed interest in designing the ring, but the [[Saskatchewan Accelerator Laboratory]] (SAL) at the [[University of Saskatchewan]] became prominent in the design. In 1991 CISR submitted a proposal to NSERC for a final design study.  This was turned down, but in later years, under President Peter Morand, NSERC became more supportive. In 1994 NSERC committee recommended a Canadian synchrotron light source and a further NSERC committee was formed to select between two bids to host such a facility, from the Universities of Saskatchewan and Western Ontario. In 1996 this committee recommended that the Canadian Light Source be built in Saskatchewan.

With NSERC unable to supply the required funds it was not clear where funding would come from. In 1997 the [[Canada Foundation for Innovation]] (CFI) was created to fund large scientific projects, possibly to provide a mechanism to fund the CLS. In 1998 a University of Saskatchewan team led by [https://artsandscience.usask.ca/profile/DSkopik Dennis Skopik], the SAL director, submitted a proposal to CFI.<ref name="Bancroft">{{Cite journal

}}</ref> The proposal was to fund 40% of the construction costs, with remaining money having to come from elsewhere. Assembling these required matching funds has been called "an unprecedented level of collaboration among governments, universities, and industry in Canada"<ref name="SPHistory">[http://media.cns-snc.ca/history/Canadian_Light_Source.html "Synchrotron: Canadian Light Source 70 years in the making'"],''The Star-Phoenix'' 20 October 2004</ref> and Bancroft – leader of the rival UWO bid – anckowledged the "Herculean" efforts of the Saskatchewan team in obtaining funds from the University, the City of Saskatoon, [[Saskatchewan Power]], NRC, the Provincial Government of Saskatchewan, and [[Western Economic Diversification]].<ref name="Bancroft"/> At a late hour CFI told the proponents that it would not accept the SAL [[LINAC]] as part of the proposal, and the resulting shortfall was met in part by the spontaneous announcement by the Saskatoon city council and then Mayor [[Henry Dayday]] that they would double their contribution as long as other partners would. On 31 March 1999 the success of the CFI proposal was announced.

The following month Skopik took a position at [[Thomas Jefferson National Accelerator Facility|Jefferson Lab]] in the USA. He decided not to stay on as director of the Saskatoon facility because his expertise was in subatomic particles, and, he argued, the head of the CLS should be a researcher who specializes in using such a facility. His successor was Mike Bancroft<ref name="SPHistory" />

===Construction: 1999–2004===

At the start of the project, all staff members with the former SAL were transferred into a new [[nonprofit organization|not-for-profit]] corporation, Canadian
Light Source Inc., CLSI, which had primary responsibility for the technical design, construction and operation of the facility. As a separate corporation from the University, CLSI had the legal and organizational freedom suitable for this responsibility. UMA, an experienced engineering firm, now part of [[AECOM]], with extensive experience managing large technical and civil construction projects, was hired as [[project management|project managers]].<ref name="CLSI">{{cite web | url=http://accelconf.web.cern.ch/accelconf/e04/papers/weilh04.pdf|title=Industrial involvement in the construction of synchrotron lightsources| year=2004 | accessdate=28 July 2012}}</ref>

The new building – attached to the existing SAL building, and measuring 84m by 83m in area with a maximum height of 23m – was completed in early 2001.<ref name="Bancroft"/> 

Bancroft's appointment ended in October 2001 and he returned to UWO, with Mark de Jong appointed acting director. Bancroft remained as acting Scientific Director until 2004.<ref>{{Cite web |url=http://www.lightsource.ca/enews/newsletter_October2001.php |title=CLS Newsletter October 2001 |access-date=17 April 2006 |archive-date=4 February 2012 |archive-url=https://web.archive.org/web/20120204083647/http://www.lightsource.ca/enews/newsletter_October2001.php |url-status=dead }}</ref>

The SAL LINAC was refurbished and placed back into service in 2002 while the booster and storage rings were still under construction.<ref name="Bancroft"/> First turn was achieved in the booster ring in July 2002 with full booster commissioning completed by September 2002.<ref name="booster">{{cite web | url=http://accelconf.web.cern.ch/accelconf/e04/PAPERS/THPKF025.PDF |title=Commissioning report of the CLS booster synchrotron | year=2004 | accessdate=22 July 2012}}</ref>

New director Bill Thomlinson, an expert in synchrotron medical imaging, arrived in November 2002. He was recruited from the [[European Synchrotron Radiation Facility]] where he had been the head of the medical research group.<ref name="Thom">{{cite web | url=http://news.usask.ca/archived_ocn/02-aug-09/news17.shtml | title=Thomlinson to head CLS Nov. 1| date=9 August 2002 | accessdate=28 July 2012}}</ref>

The 1991 proposal to NSERC envisioned a 1.5 GeV storage ring, since at this time the interest of the user community was mainly in the soft X-ray range. The ring was a racetrack layout of four to six [[dipole magnet|bend]] regions surrounding straights with extra [[quadrupole magnets|quadrupoles]] to allow for variable functions in the straights. The design contemplated the use of [[superconductivity|superconducting]] bends in some locations to boost
the [[photon]] energies produced. The drawback of this design was the limited number of straight sections. In 1994 a more conventional machine with 8 straight sections was proposed, again with 1.5 GeV energy. At this time more users of hard X-rays were interested and it was felt that both the energy and number of straight sections were too low. By the time funding was secured in 1999 the design had changed to 2.9 GeV, with longer straight sections to enable two [[insertion devices]] per straight, delivering beam to two independent beamlines.<ref name="SR">{{cite web | url= http://accelconf.web.cern.ch/accelconf/p03/PAPERS/TOPA001.PDF| title=The Canadian Light Source | year=2003 | accessdate=25 July 2012}}</ref>

Construction of the storage ring was completed in August 2003 and commissioning began the following month. Although beam could be stored, in March 2004 a large obstruction was found across the center of the chamber. Commissioning proceeded quickly after this was removed, and by June 2004 currents of 100mA could be achieved .<ref name="comm">{{cite web | url=http://accelconf.web.cern.ch/Accelconf/e04/PAPERS/THPKF007.PDF | title=Canadian Light Source status and commissioning results | year=2004 | accessdate=22 July 2012}}</ref>

On 22 October 2004 the CLS officially opened, with an opening ceremony attended by federal and provincial dignitaries, including then-Federal [[Minister of Finance (Canada)|Minister of Finance]] [[Ralph Goodale]] and then-[[Premier of Saskatchewan|Saskatchewan Premier]] [[Lorne Calvert]], university presidents and leading scientists. October 2004 was declared "Synchrotron Month" by the city of Saskatoon and the Saskatchewan government.<ref>{{cite web|url= http://news.usask.ca/archived_ocn/04-sep-24/news07.shtml|title= October declared Synchrotron Month |date=24 September 2004 |accessdate=26 July 2012}}</ref> [[Peter Mansbridge]] broadcast the [[Canadian Broadcasting Corporation|CBC]]'s nightly [[newscast]] [[The National (CBC)|''The National'']] from the top of the storage ring the day before the official opening.<ref name="National">{{cite web | url=http://news.usask.ca/archived_ocn/04-nov-05/news01.shtml| title=Dignitaries gather to mark synchrotron's grand opening| date=5 November 2004| accessdate=8 May 2012}}</ref> In [[Parliament of Canada|parliament]] local [[Member of Parliament|MP]] [[Lynne Yelich]] said "There were many challenges to overcome, but thanks to the vision, dedication and persistence of its supporters, the Canadian Light Source synchrotron is open for business in Saskatoon."<ref>{{cite web|url= https://openparliament.ca/debates/2004/10/21/lynne-yelich-1/only/|title= Lynne Yelich on Canadian Light Source |date=21 October 2004 |accessdate=26 July 2012}}</ref>

[[Image:Brockhouse construction.jpg|thumb|left|250px|The expansion for the Brockhouse beamlines under construction in July 2012]]
The initial funding included seven beamlines, referred to as Phase I, which covered the full spectral range: two [[infrared]] beamlines, three soft X-ray beamlines and two hard X-ray beamlines.<ref name="Bancroft" /> Further beamlines were built in two further phases, II (7 beamlines) and III (5 beamlines), announced in 2004 and 2006 respectively. Most of these were funded through applications to CFI by individual universities including UWO, the [[University of British Columbia]] and [[Guelph University]]<ref name="progress" />

In March 2005 leading infrared researcher Tom Ellis joined the CLS from [[Acadia University]] as Director of Research.

Scientists from [[Stanford University]] worked with CLS scientists to design a cleaner, faster [[battery (electricity)|battery]]. The new battery charges in less than two minutes, thanks to a newly developed [[carbon]] [[nanostructure]]. The team grew nanocrystals of iron and nickel on carbon. Traditional batteries lack this structure, mixing iron and nickel with conductors more or less randomly. The result was a strong chemical bond between the materials, which the team identified and studied at the synchrotron.<ref name="Battery">{{cite web | url=http://phys.org/news/2012-07-cleaner-faster-battery.html|title=A cleaner, faster battery| date= 9 July 2012 | accessdate=28 July 2012}}</ref>

A collaboration between the [[University of Regina]] and the [[Royal Saskatchewan Museum]] has been investigating [[dinosaur]] [[fossil]]s at the CLS, including "Scotty," a [[Tyrannosaurus]] found in Saskatchewan in 1991, one of the most complete and largest T-rex skeletons ever found. They looked at the concentration of elements in bones to study the impact of the environment on such animals.<ref name="Barbi">{{cite web | url=http://thechronicleherald.ca/canada/46870-professor-uses-new-technology-shed-light-dinosaur-bones|title=Professor uses new technology to shed light on dinosaur bones | date= 28 December 2011 | accessdate=27 July 2012}}</ref>

==Industrial program and economic impact==
[[Image:Cellphone X-ray.jpg|thumb|left|110px|Image of a cellphone taken at CLS]]

From inception, the CLS showed a "strong commitment to industrial users and private/public partnerships", with then-director Bancroft reporting "more than 40 letters of support from industry indicating that [the CLS] is important for what they do". The CLS has an industrial group, within the larger experimental facilities division, with industrial liaison scientists who make synchrotron techniques available to a "non-traditional" user base who are not synchrotron experts. By 2007 more than 60 projects had been carried out,<ref name="tool" /> although in a speech in the same year, then-CLS director Bill Thomlinson said that "one of the biggest challenges for the synchrotron...is to get private users through the door", with less than 10% of time actually used by industry.
 
In 1999 then-Saskatoon mayor Dayday stated that "the CLS will add $122 million to Canada's GDP during construction and $12 million annually after that". An [[economic impact analysis|economic impact study]] of the two [[financial year]]s 2009/10 and 10/11 showed the CLS had added $45 million per year to the Canadian GDP, or about $3 for every $1 of operating funding.<ref name="impact">{{cite web |url=http://www.lightsource.ca/media/media_release_20111122.php |title=Canadian Light Source making positive economic, scientific impacts for Canada |date=22 November 2011 |accessdate=24 July 2012 |archive-date=4 June 2016 |archive-url=https://web.archive.org/web/20160604114039/http://www.lightsource.ca/media/media_release_20111122.php |url-status=dead }}</ref>

The CLS has stated that "the primary means of accessing the CLS is through a system of peer review, which ensures that the proposed science is of the highest quality and permits access to the facility to any interested researcher, regardless of regional, national, academic, industrial or governmental affiliation."<ref name="progress" />

==Medical isotope project==

With the [[National Research Universal reactor|NRU]] reactor at the [[Chalk River Laboratories]] due to close in 2016, there was a need to find alternative sources of the medical isotope [[technetium-99m]], a mainstay of [[nuclear medicine]]. In 2011 the Canadian Light Source received $14 Million in funding to investigate the feasibility of using an electron [[LINAC]] to produce [[molybdenum-99]], the parent isotope of technetium-99.<ref name="CBCisotopes">{{cite news|url=https://www.cbc.ca/news/canada/saskatchewan/sask-synchrotron-to-make-medical-isotopes-1.1121457 |title=Sask.

==Education program==
[[Image:Students on the beamline.jpg|thumb|left|250px|High school students from La Loche at the Canadian Light Source]]
The CLS has an education program – "Students on the Beamlines" – funded by NSERC Promoscience. This outreach program for science allows high school students to fully experience the work of a scientist, in addition to having the chance to use the CLS beamlines.

"The program allows students the development of active research, a very rare phenomena in schools and provides direct access to the use of a particle accelerator, something even rarer!" said teacher Steve Desfosses form College Saint-Bernard, [[Drummondville]], Quebec.<ref name="Express">[http://www.journalexpress.ca/Soci%C3%A9t%C3%A9/%C3%89ducation/2012-03-03/article-2914331/Le-synchrotron-de-Saskatoon-mis-a-la-portee-de-jeunes-scientifiques-du-College-SaintBernard/1 "Le synchrotron de Saskatoon mis à la portée de jeunes scientifiques du Collège Saint-Bernard"] {{Webarchive|url=https://archive.today/20130115150408/http://www.journalexpress.ca/Soci%C3%A9t%C3%A9/%C3%89ducation/2012-03-03/article-2914331/Le-synchrotron-de-Saskatoon-mis-a-la-portee-de-jeunes-scientifiques-du-College-SaintBernard/1 |date=15 January 2013 }},''L'Express'' 3 March 2012</ref>

===Accelerators===
[[Image:CLS synchrotron.jpg|thumb|right|250px|The booster and storage rings inside the experimental hall]]
[[File:SGM - PGM EPUs in straight 11 at the Canadian Light Source.jpg|thumb|250x250px|Chicaned undulators inside the storage ring]]

====Injection system====

The injection system consists of a 250 MeV LINAC, a low energy transfer line, a 2.9 GeV booster synchrotron and a high energy transfer line.<ref name="Injection">{{cite web | url=http://accelconf.web.cern.ch/accelconf/e04/papers/thpkf008.pdf| title=Injection system for the Canadian Light Source | year=2004 | accessdate=7 July 2012}}</ref> The LINAC was operated for over 30 years as part of the Saskatchewan Accelerator Lab<ref name="update 2001">{{cite journal | url=http://accelconf.web.cern.ch/accelconf/e04/papers/thpkf008.pdf|title=The Canadian Light Source: an update |journal=19th Particle Accelerator Conference (Pac 2001) |pages=2680 | year=2001 | accessdate=7 July 2012|bibcode=2001pac..conf.2680B |last1=Blomqvist |first1=I. |last2=Dallin |first2=L. |last3=Hallin |first3=E. |last4=Lowe |first4=D. |last5=Silzer |first5=R. |last6=De Jong |first6=M. }}</ref> and operates at 2856&nbsp;MHz. The 78m low energy transfer line takes the electrons from the below-ground LINAC to the ground level booster in the newer CLS building, via two vertical chicanes. The full energy 2.9 GeV booster, chosen to give high orbit stability in the storage ring, operates at 1&nbsp;Hz, with an RF frequency of 500&nbsp;MHz, unsynchronised with the LINAC. This results in significant beam loss at the extraction energy.<ref name="Injection"/>

====Storage ring====

The storage ring cell structure has a fairly compact lattice with twelve straight sections available for injection, [[microwave cavity|RF cavities]] and 9 sections available for insertion devices. Each cell has two bending magnets detuned to allow some dispersion in the straights – the so-called double-bend achromat structure – and thus reduce the overall beam size. As well as the two bend magnets each cell has three families of quadrupole magnets and two families of [[sextupole magnet]]s. The ring circumference is 171m, with a straight section length of 5.2m.<ref name="PAC2001">{{cite journal | url=http://lss.fnal.gov/archive/proceedings/PAPERS/WPPH093.PDF | title=The Canadian Light Source: an update | journal=19th Particle Accelerator Conference (Pac 2001) | pages=2680 | year=2001 | accessdate=28 July 2012 | archive-url=https://web.archive.org/web/20140502032624/http://lss.fnal.gov/archive/proceedings/PAPERS/WPPH093.PDF | archive-date=2 May 2014 | url-status=dead | df=dmy-all | bibcode=2001pac..conf.2680B | last1=Blomqvist | first1=I. | last2=Dallin | first2=L. | last3=Hallin | first3=E. | last4=Lowe | first4=D. | last5=Silzer | first5=R. | last6=De Jong | first6=M. }}</ref> The CLS is the smallest of the newer synchrotron facilities, which results in a relatively high horizontal [[beam emittance]] of 18.2&nbsp;nm-rad.<ref name="Newest" />  The CLS was also one of the first facilities to [[chicane]] two [[undulator]]s in one straight section, to maximize the number of insertion device beamlines.<ref name="SRNupdate"/>

All five of the phase I X-ray beamlines use insertion devices. Four use permanent magnet undulators designed and assembled at the CLS, including one in-vacuum undulator and one elliptically polarized undulator (EPU). The HXMA beamline uses a superconducting [[wiggler (synchrotron)|wiggler]] built by the [[Budker Institute of Nuclear Physics]] in [[Novosibirsk]].<ref name="SRNupdate"/> Phase II added two further devices including another Budker superconducting wiggler, for the BMIT beamline.<ref name="ID">{{cite web| url=http://www.lightsource.ca/operations/insertion_devices.php| title=Insertion devices| accessdate=28 July 2012| archive-date=28 July 2012| archive-url=https://web.archive.org/web/20120728075202/http://www.lightsource.ca/operations/insertion_devices.php| url-status=dead}}</ref> Phase III will add four more devices, filling 8 of the 9 available straight sections.

==== Superconducting RF cavity ====
The CLS was the first light source to use a [[Superconducting radio frequency|superconducting RF (SRF) cavity]] in the storage ring from the beginning of operations.<ref name="SRNupdate" /> The [[niobium]] cavity is based on the 500&nbsp;MHz design used at the [[Cornell Electron Storage Ring]] (CESR) which allows potentially beam-perturbing high order modes to propagate out of the cavity where they can be very effectively damped.<ref name="PAC2001" />  The superconducting nature of the niobium cavity means only 0.02% of the RF power put into the cavity is wasted in heating the cavity as compared to roughly 40% for normal-conducting (copper) cavities.  However, a large portion of this power saving - about 160&nbsp;kW out of the 250&nbsp;kW saved - is needed to power the cryogenic plant required to supply liquid helium to the cavity.  The SRF cavity at CLS is fed with RF from a 310&nbsp;kW Thales klystron.
