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. A large scale simulation effort is presented in the paper, which leads to a better quantitative understanding of the existing PSI high power proton cyclotron facility and predicts the beam behavior of CYCIAE-100 under construction at CIAE. The beam power of 1.3 MW delivered by the PSI 590 MeV Ring Cyclotron together with stringent requirements regarding the controlled and uncontrolled beam losses poses great challenges to predictive simulations. The comparisons with measurements show that OPAL can precisely predict the radial beam pattern at extraction with large dynamic range (3-4 orders of magnitude). The new particle matter interaction model is used to obtain necessary beam loss statistics during the acceleration. This data is indispensable in the design of an efficient collimation system in CYCIAE-100.

An overview is given on beam diagnostics used at cyclotrons. The focus is set to devices installed inside the cyclotron with its special "environmental" conditions and limitations and on techniques which cover specific needs of the commissioning and operation of cyclotrons.
