  Su­per­con­duct­ing cav­i­ties with two beam pipes had been pro­posed in the past for en­ergy re­cov­ery linac ap­pli­ca­tions. The rel­a­tively com­plex geom­e­try of those cav­i­ties pre­sented a se­ri­ous chal­lenge for fab­ri­ca­tion and sur­face pro­cess­ing. Main con­cerns have now been over­come with the pro­duc­tion and suc­cess­ful RF test­ing of a new el­lip­ti­cal twin-axis cav­ity pro­posed by Jef­fer­son Lab and op­ti­mized by the Cen­ter for Ac­cel­er­a­tor Sci­ence at Old Do­min­ion Uni­ver­sity in the frame of a DoE ac­cel­er­a­tor stew­ard­ship pro­gram. The cav­ity de­sign pro­vides uni­form ac­cel­er­at­ing or de­cel­er­at­ing fields for both beams. This paper de­scribes the cav­ity de­sign, fab­ri­ca­tion ex­pe­ri­ence, and the first cold RF test re­sults and ex­plores po­ten­tial ap­pli­ca­tions es­pe­cially for Jef­fer­son Lab s EIC (JLEIC).

Op­ti­miza­tion of the dual axis asym­met­ric cav­ity was per­formed to min­i­mize the ratio of the peak mag­netic and elec­tric fields val­ues to the ac­cel­er­at­ing volt­age, to in­crease the dis­tance be­tween op­er­at­ing and neigh­bour­ing modes as well as to re­duce the man­u­fac­tur­ing cost of the cav­ity. To reach the goals sev­eral so­lu­tions have been sug­gested bring­ing the ra­tios to the ac­cept­able val­ues and lead­ing to sim­pli­fi­ca­tion of the man­u­fac­tur­ing of the struc­ture.

  PERLE is a pro­posed multi-pass En­ergy Re­cov­ery Linac, based on SRF tech­nol­ogy, to be built at Orsay, France, in a col­lab­o­ra­tive ef­fort be­tween local lab­o­ra­to­ries LAL/IN2P3, IPNO/IN2P3 and in­ter­na­tional part­ners such as JLAB, STFC, Liv­er­pool Uni­ver­sity, BINP and CERN. A part from ex­per­i­men­tal pro­gram, PERLE will serve as test­bed to study a broad range of ac­cel­er­a­tor phe­nom­ena and to val­i­date tech­ni­cal choices for the LHeC, which aims at elec­tron pro­ton col­li­sions using the ex­ist­ing LHC ma­chine to­gether with an added elec­tron ERL. In its final con­fig­u­ra­tion, PERLE pro­vides a 500 MeV elec­tron beam using high cur­rent (20 mA) ac­cel­er­a­tion dur­ing three passes through 801.6 MHz cav­i­ties. This talk out­lines the tech­no­log­i­cal choices, the lat­tice de­sign and de­scribes the po­ten­tial con­tri­bu­tions of the in­ter­ested part­ners.
