Dose monitors and position monitors are critical equipment for particle therapy facilities. Performance of the monitors affects precision of irradiation dose and dose distribution. Parallel plate ionization chambers with free air are adopted for dose monitors and position monitors. Radiation-hardened front-end electronics are integrated in the chambers, and the output of the chambers are digital signals. The structure of the monitors is compact, modularized and easy-to-use. The ionization chambers are implemented successfully in Shanghai Advanced Proton Therapy Facility. The development details and implementation status are presented.
