Beam dynamics simulation for the high intensity DAEdALUS cyclotrons

[摘要] In the DAEδALUS (Decay-At-rest Experiment for δ[subscript CP] studies At the Laboratory for Underground Science) project, high power H[+ over 2] cyclotron chains are proposed to efficiently provide proton beams with a kinetic energy of 800 MeV and an average power in the MW range. Space charge plays a pivotal role in both the injector and the ring cyclotrons. Large-scale particle simulations show that the injector cyclotron is a space charge dominated cyclotron and that a 5 mA beam current can be extracted with tolerable beam losses on the septum. In contrast, in the ring cyclotron, no space charge induced beam loss is observed during acceleration and extraction.
