=== FARAD ===

''FARAD'', which stands for ''Faraday accelerator with radio-frequency assisted discharge'', is a lower-power alternative to the PIT that has the potential for space operation using current technologies.<ref>{{cite conference|last1= Choueiri|first1= Edgar Y.|last2= Polzin|first2= Kurt A.|title= Faraday Acceleration with Radio-frequency Assisted Discharge (FARAD)|date= July 2004|conference= 40th AIAA/ASME/SAE/ASEE Joint Propulsion Conference and Exhibit|location= Fort Lauderdale, Florida|url=https://massless.info/images/choueiri-jpc-2004-3940.pdf |archive-url=https://web.archive.org/web/20221120111018/https://massless.info/images/choueiri-jpc-2004-3940.pdf |archive-date=2022-11-20 |url-status=live|format= PDF|doi=10.2514/6.2004-3940 }}</ref><ref>{{cite conference|last1= Dankanich|first1= John W.|last2= Polzin|first2= Kurt A.|title=Mission Assessment of the Faraday Accelerator with Radio-Frequency Assisted Discharge (FARAD)|date= July 2008|conference=44th AIAA/ASME/SAE/ASEE Joint Propulsion Conference|location= Hartford, CT|url=https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20090001283.pdf |archive-url=https://ghostarchive.org/archive/20221009/https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20090001283.pdf |archive-date=2022-10-09 |url-status=live|doi=10.2514/6.2008-4517 |hdl= 2060/20090001283|hdl-access= free}}</ref>

In the PIT, both propellant ionization and acceleration are performed by the HV pulse of current in the induction coil, while FARAD uses a separate inductive RF discharge to preionize the propellant before it is accelerated by the current pulse. This preionization allows FARAD to operate at much
lower discharge energies than the PIT (100 joules per pulse vs 4 kilojoules per pulse) and allows for a reduction in the thruster's size.<ref>{{cite thesis|last=Polzin|first=Kurt Alexander|date=June 2006|title=Faraday Accelerator with Radio-frequency Assisted Discharge (FARAD)|type=Ph.D.|publisher=[[Princeton University]]|url=http://www-personal.umich.edu/~ianrit/PIT/PolzinThesis.pdf |archive-url=https://ghostarchive.org/archive/20221009/http://www-personal.umich.edu/~ianrit/PIT/PolzinThesis.pdf |archive-date=2022-10-09 |url-status=live}}</ref>
