Beam forming system modernization at the MMF linac proton injector

Beam forming system modernization at the MMF linac proton injector

The isolation improvements of the beam forming system (BFS) of the ММF linac proton injector ion source are reported. The mean beam current and, accordingly, BFS electrode heating were increased when the ММF linac has began to operate regularly in long beam sessions with 50 Hz pulse repetition rate....
