The NPS FEL Group and Niowave are col­lab­o­rat­ing to de­sign sev­eral FEL sys­tems using su­per­con­duct­ing spoke RF cav­i­ties. Ac­cel­er­a­tors reach­ing elec­tron beam en­er­gies of 2MeV to 75MeV with mil­liamps of av­er­age cur­rent are con­sid­ered to drive FELs using a short ten pe­riod un­du­la­tor, ap­prox­i­mately 30cm long. The co­her­ent ra­di­a­tion ranges from THz to in­frared de­pend­ing on the elec­tron beam en­ergy. In the 2MeV ac­cel­er­a­tor, the ra­di­a­tion process can be su­per-ra­di­ant due to the long mil­lime­ter wave­length, while the 40MeV ac­cel­er­a­tor gen­er­ates in­frared wave­lengths in a con­ven­tional FEL os­cil­la­tor con­fig­u­ra­tion. An in­ter­me­di­ate 8MeV ac­cel­er­a­tor pow­ers an FEL os­cil­la­tor with short pi­cosec­ond pulses pro­vid­ing a kilo­watt of THz power in a com­pact source. Comp­ton backscat­ter­ing is de­scribed to gen­er­a­tor in­co­her­ent, but mono­chro­matic x-rays for med­ical ap­pli­ca­tions.

The sta­tus of FEL-based Co­her­ent Elec­tron Cool­ing Proof-of-prin­ci­ple Ex­per­i­ment at BNL is pre­sented. The ex­per­i­men­tal set-up is com­prised of a 2 MeV CW SRF elec­tron gun and 20 MeV CW SRF linac and 8-m long he­li­cal FEL am­pli­fier. The sta­tus of the ac­cel­er­a­tor com­mis­sion­ing, and progress in the con­struc­tion of the he­li­cal un­du­la­tor at Bud­ker INP, is also re­ported
