  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.
