【 摘 要 】

High power proton machines consume a large amount of energy. Thus, the energy efficiency of grid to beam power conversion is particularly important for the overall power consumption of such facilities. In this study, we analyse the energy efficiency of PSI's cyclotron-based HIPA facility, which presently delivers a maximum of 1.4 MW beam power. The total power consumption of the entire facility is 12.5 MW at 2.2 mA beam current (1.3 MW). Main power consumers are: RF systems, electromagnets, water cooling and auxiliary systems including infrastructure, each consuming 5.3 MW, 3.6 MW, 1.65 MW and 1.95 MW, respectively. HIPA's grid to beam efficiency is 18.3% when considering only those parts of any subsystems (RF components, magnets, cooling, and auxiliary systems), which are minimally required to produce a full 1.3 MW beam. The dependency of individual subsystems on beam power was also studied. These findings serve as a basis for further optimizations of the HIPA facility and give a reference of the efficiency estimate for the cyclotron-based high power machines.
