4. 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.
