The CBETA project [1] is the first and unique of its kind electron accelerator which combines two accelerator concepts together. The Energy Recovery Linac (ERL) and the Fixed Field Alternating Gradient (FFA_G) concepts. The CBETA project is currently in the commissioning stage and some of the beam optics of the accelerator has be done using lamp-magnet methods to describe the fields of the...

Intense negative muon is useful for reduction and recycling the radioactive wastes from nuclear plants. As an intense negative muon source, MERIT(Multiplex Energy Recovery Internal Target) scheme was proposed. To prove the principle of the MERIT scheme, FFA ring (MERIT-PoP ring) has been developed and the beam experiment was carried out. In this presentation, the detail of this study will be reported.

13. CBETA: a 4-pass superconducting ERL with permanent FFA magnet return arc

Beam commissioning is currently in progress for the CBETA ERL recently built at Cornell University in collaboration with BNL. This machine has a 6MeV injector and 36MeV main superconducting RF module at ~1.3GHz frequency. The beam is designed to pass through the main RF up to four times accelerating and four times decelerating, before being dumped at 6MeV. These four energies (42, 78, 114,...
