Editing X-ray microscope (section)

==== Advanced Light Source ====
The Advanced Light Source (ALS) in Berkeley, California, is home to XM-1, a full-field soft X-ray microscope operated by the Center for X-ray Optics and dedicated to various applications in modern nanoscience, such as nanomagnetic materials, environmental and materials sciences and biology. XM-1 uses an X-ray lens to focus X-rays on a CCD, in a manner similar to an optical microscope. XM-1 held the world record in spatial resolution with Fresnel zone plates down to 15&nbsp;nm and is able to combine high spatial resolution with a sub-100ps time resolution to study e.g. ultrafast spin dynamics. In July 2012, a group at [[DESY]] claimed a record spatial resolution of 10&nbsp;nm, by using the hard X-ray scanning microscope at [[PETRA III]].<ref>[https://web.archive.org/web/20120628180429/http://hasylab.desy.de/news__events/announcements/coherent_x_ray_scanning_microscopy_at_petra_iii_reached_10_nm_resolution_june_2012/index_eng.html Coherent X-Ray scanning microscopy at PETRA III reached 10 nm resolution (June 2012)].

The ALS is also home to the world's first soft x-ray microscope designed for biological and biomedical research. This new instrument, XM-2 was designed and built by scientists from the National Center for X-ray Tomography. XM-2 is capable of producing 3-dimensional [[X-ray microtomography|tomograms]] of cells.
