Beam Stoppers General Presentation
4
Beam stoppers 160MeV
Maximum H- Current 40 mA
Pulse Length 400µs
Max Rep-Rate (1.1Hz)
Beam Energy 160 MeV
Beam parameters:
“A beam stopper is a mechanical safety device used to intercept a particle beam, to guarantee the personnel safety. (L. Bettazzi, C. Maglioni, EDMS xxx under definition)
S. Cimmino, EN-STI, Linac4 Beam Coordination Committee – Meeting 31
The beam stopper 160 MeV has been designed considering a possible unification between all the beam stoppers from Linac to Ps.
