Beam-loss criteria for heavy ion accelerators


Peter Katrík (Technische Universität Darmstadt)


The activation of the high-energy heavy ion accelerators due to beam-losses is a serious issue for parts of accelerator as collimator systems, magnets, beam-line, fragment separator targets, etc. The beam-losses below 1 W/m are considered as a tolerable for “hands-on” maintenance on proton machines. In our previous studies FLUKA2008 code has been used for establishing a scaling law expanding the existing proton beam-loss tolerance to heavy-ion beams. This scaling law enabled specifying beam-loss criteria for projectile species from proton up to uranium at energies from 200 MeV/u up to 1 GeV/u. FLUKA2008 allowed nucleus-nucleus interactions down to 100 MeV/u only. In this work we revise our previous results and extend them towards lower energies with the help of new FLUKA code version. FLUKA2011 includes a nucleus-nucleus interaction below 100 MeV/u. This research has been done at GSI Darmstadt and is supported by project 05P12RDFN6.
