Compared to other therapies, heavy particle radiotherapy can cause more intensive damage to cancer cells. Carbon ions have attracted attention as a useful treatment due to their sharp Bragg peaks, but there are concerns about low-dose exposure of surrounding cells due to the secondary particles generated. The double-differential cross section (DDX) of charged particles produced by the carbon-matter fragmentation reaction is important in assessing the dose given to surrounding healthy cells. The experiment was carried out at the HIMAC in QST, where emitted charged particle production was measured using 100 or 180 MeV/u carbon particle beams. The emitted charged particles were measured with a spectrometer consisting of a silicon semiconductor detector (SSD) and a crystal scintillation detector (CsI (Tl)) and particles were identified in the range 15°~40° from H~C.
