SARAF Phase-I Experience with mA Beams | |
|
||
| The RF superconducting (SC) linac at the Soreq Applied Research Accelerator Facility (SARAF) is designed for CW 5 mA 40 MeV proton and deuteron beams. SARAF Phase-I has been built to test and characterize the required novel technologies. Phase-I includes a 20 keV/u ECR ion source, a LEBT, a 4 m long 176 MHz 4-rod RFQ, a short MEBT, one 4K SC module that hosts 6 HWRs and 3 SC solenoids and 13 m long beam lines for beam and basic studies. Since 2011, SARAF Phase-I was the first accelerator to use HWR and the first to accelerate variable energy 2 mA CW protons beam. Beam dynamics simulations are used in the design phase, for everyday beam tuning and for beam studies. However, the simulation predictions of the RFQ transmission and the SC linac beam loss don’t reach the required level of confidence. This is assumed to be due to unknown absolute values of initial beam distribution, LEBT space charge compensation, components misalignment and more. The experience of matching beam dynamics phenomena to beam measurements will be presented. | ||
