Description
In the DAE$\delta$ALUS (Decay-At-rest Experiment for $\delta_{CP}$ studies At the Laboratory for Underground Science) project, ultra-high power proton cyclotrons are proposed, which should efficiently provide the necessary proton beams in the range of 1 to 8 MW with a kinetic energy up to 800 MeV.
The evaluation of space charge effects are challenging, for both the injector cyclotron (DIC) and the main ring cyclotron (DSRC).
We report on precise calculations w.r.t. high intensity problems for both machines. Large scale particle simulations show, that in the current design, the beam losses are associated to the single turn
extraction in the DIC. This constitutes the bottleneck in achieving more than 5 mA of H2+ beam. On the other hand, in the DSRC, with multi turn and stripping extraction, space charge plays a minor role.
