As for particle therapy accelerators, either based on cyclotrons or synchrotrons, the extracted beams are very weak, usually on the level of nano-Amperes. Up to date, the commonly used detectors in such low current machines are all destructive, such as fluorescent screens and gas ionization chambers. In this paper, we proposed for the first time to use a residual gas ionization monitor to measure the beam profiles in a proton therapy facility based on a superconducting cyclotron. The feasibility of such a scheme and some basic issues are discussed in this paper.
