Beam dynamics validation of the Halbach Technology FFAG Cell for Cornell-BNL Energy Recovery Linac
- Brookhaven National Laboratory (BNL), Upton, NY (United States)
The Cornell-BNL Electron Test Accelerator (CBETA), a 150 MeV energy recovery linac (ERL) now in construction at Cornell, employs a fixedfield alternating gradient (FFAG) optics return loop: a single beam line comprised of quadrupole doublet cells, which accepts four recirculated energies. CBETA FFAG cell uses Halbach permanent magnet technology, its design studies have covered an extended period of time supported all the way by extensive particle dynamics simulations using computed 3-D field map models. This approach, which supported the choice of Halbach technology for CBETA FFAG ERL in 2016, is discussed and illustrated here based on the final stage in these beam dynamics studies, namely the validation of a ultimate, optimized design of the cell.
