Description
At the Nuclear Research Center SCK CEN in Belgium, the first phase of the MYRRHA project (an accelerator driven system) is under construction. Included in MYRRHA Phase 1 are a normal conducting injector linac (RFQ + CH cavities) and a super conducting linac (60 single spoke cavities), providing a CW proton beam of 4 mA and 100 MeV.
In this contribution the recent changes to the MYRRHA Phase 1 linac design and the associated machine physics studies are reported. First of all, the layout of the MYRRHA linac was changed from two identical injector linacs each including a dog leg to one straight injector (for the MYRRHA phase 1) and a (future) second injector with a dogleg. The beam dynamics studies of the straight linac and two options for the second injector are presented. Secondly, the impact of a detailed mechanical integration of the beam line elements, which is a compromise between the ideal theoretical layout and a realistic and pragmatic implementation, on the longitudinal and transverse phase space distributions is discussed. Finally, the losses along the linac and their relation to the RFQ output distribution are presented.
