Description

A front-end electronics of dose monitor has been developed for measuring irradiation dose to the patient in Shanghai Advanced Proton Therapy Facility. The parallel plate ionization chamber is used for the dose monitoring. Unlike the traditional method of recycling capacitor integration and voltage-to-frequency conversion, this dose monitor electronics uses the trans-impedance amplifier and analog-to-digital conversion method. It performs satisfactorily, with the integral nonlinearity of less than ±0.04 nA in the range of -400 to 50 nA and the resolution of about ±0.6 nA. (authors)
