- Abstract
- Resistive plate chambers are studied for in-vivo beam verification in particle therapy. A four-gap glass RPC is constructed with 1.1-mm-thick floating glass and tested with 662-keV gamma rays emitted from a 5-GBq Cs-137 source, as well as high-energy photons induced by 140-MeV raster-scan-mode proton beams provided by the Samsung Proton Therapy Center. The desired 3 mm resolution of the RPC detector is confirmed by reconstructing gamma transmission images for the cesium gammas gathered from the data. Using the described RPC detector and a 10-cm-thick lead collimator, we obtain two-dimensional gamma-ray images for 140-MeV proton beams and confirm the detector technology proposed in the present research.
