The H2020 Com­pact­Light Pro­ject aims for the de­sign of in­no­v­a­tive, cost-ef­fec­tive, com­pact FEL fa­cil­i­ties to gen­er­ate higher peak bril­liance ra­di­a­tion in the soft and hard X-ray. In this paper we as­sess via sim­u­la­tion stud­ies the per­for­mance of a vari­ably po­lar­is­ing AP­PLE-X af­ter­burner po­si­tioned down­stream of a he­li­cal Super Con­duct­ing Un­du­la­tor (SCU). We dis­cuss the op­ti­mum bal­ance be­tween the ac­tive SCU length and the af­ter­burner length, con­sid­er­ing the peak bril­liance and pulse en­ergy of the out­put. Our stud­ies are com­ple­mented with analy­sis of the op­ti­cal beam qual­ity of the af­ter­burner out­put to de­ter­mine the de­sign con­straints of the pho­ton beam­line that de­liv­ers the FEL out­put to the ex­per­i­men­tal areas.

  In­verse Comp­ton scat­ter­ing (ICS) holds the po­ten­tial for fu­ture high flux, nar­row band­width x-ray sources dri­ven by high qual­ity, high rep­e­ti­tion rate elec­tron beams. CBETA, the Cor­nell-BNL En­ergy re­cov­ery linac (ERL) Test Ac­cel­er­a­tor, is the world’s first su­per­con­duct­ing ra­diofre­quency multi-turn ERL, with a max­i­mum en­ergy of 150 MeV, ca­pa­ble of ICS pro­duc­tion of x-rays above 400 keV. We pre­sent an up­date on the by­pass de­sign and an­tic­i­pated pa­ra­me­ters of a com­pact ICS source at CBETA. X-ray pa­ra­me­ters from the CBETA ICS are com­pared to those of lead­ing syn­chro­tron ra­di­a­tion fa­cil­i­ties, demon­strat­ing that, above a few hun­dred keV, pho­ton beams pro­duced by ICS out­per­form those pro­duced by un­du­la­tors in term of flux and bril­liance.
