TOWARDS QUANTITATIVE PREDICTIONS OF HIGH POWER CYCLOTRONS

The large and complex structure of cyclotrons poses great challenges in the precise simulation of high power beams. However, such simulation capabilities are mandatory in the design and operation of the next generation high power proton drivers. The powerful tool OPAL enables us to do large scale simulations including 3D space charge and particle matter interactions. We describe a large scale simulation effort, which leads to a better quantitative understanding of the existing PSI high power proton cyclotron facility and predicts the beam behaviour of CYCIAE-100 under construction at CIAE.
