Beam Stoppers General Presentation S. Cimmino, EN-STI, Linac4 Beam Coordination Committee - Meeting 20
Beam stoppers 160MeV 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) Beam parameters: The beam stopper 160 MeV has been designed considering a possible unification between all the beam stoppers from Linac to Ps. Maximum H- Current 40 mA Pulse Length 400µs Max Rep-Rate (1.1Hz) Beam Energy 160 MeV S. Cimmino, EN-STI, Linac4 Beam Coordination Committee – Meeting 31
