Description
Multi-gap resistive plate chamber are studied for range verification in particle therapy. Four- and six-gap glass RPCs were constructed with 0.45- and 1.1-mm-thick floating glass and tested with 662-keV gamma rays emitted from a 5-GBq Cs-137 source and high-energy photons induced by 44-MeV proton beams provided by the MC50 cyclotron at the Korea Institute of Radiological Accelerator Medical Sciences (KIRAMS). The two-dimensional images of the gammas were obtained by using a 5-cm-thick lead collimator with 10-mm-pitch 4-mm-diameter holes. The gamma images of a beam-activated area formed in a 2-cm-thick acrylic phantom agree well with data predicted using GEANT4 simulations.
