The Long-Term Beam Losses in the CERN Injector Chain / Gilardoni, Simone (CERN) ; Bartosik, Hannes (CERN) ; Benedetto, Elena (CERN) ; Damerau, Heiko (CERN) ; Forte, Vincenzo (Universite Blaise Pascal (FR)) ; Giovannozzi, Massimo (CERN) ; Goddard, Brennan (CERN) ; Hancock, Steven (CERN) ; Hanke, Klaus (CERN) ; Huschauer, Alexander (CERN) et al.
For the production of the LHC type beams, but also for the high intensity ones, the budget allocated to losses in the CERN injector chain is maintained as tight as possi- ble, in particular to keep as low as possible the activation of the different machine elements. Various beam dynamics effects, like for example beam interaction with betatronic resonances, beam instabilities, but also reduced efficiency of the RF capture processes or RF noise, can produce losses even on a very long time scale. [...]
