Isochronous cyclotrons have no longitudinal focusing at low beam intensities. However, at high intensities the space charge force induces coupling of longitudinal and horizontal motion. This effect is used in the INJECTOR II cyclotron and allows operation without flattop cavity. The linear coupling terms are modeled and analyzed with emphasis on the cyclotron phase curve.

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)...

The PSI medical cyclotron COMET is modelled using the program OPAL, a tool developed at PSI for charged particle optics in accelerator structures and beam lines. For the proper simulation of the COMET cyclotron including the crucial central region, a new feature is introduced to OPAL, which enables a versatile combination of multiple 3D field maps for the acceleration. For the beam collimation...
