摘要：

In the DAE delta ALUS (Decay-At-rest Experiment for delta(CP) studies At the Laboratory for Underground Science) project, high power H-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. (C) 2012 Elsevier B.V. All rights reserved.
