초록

Here, we report on the development of a beam-scan detector that can quantitatively measure proton-beam profiles. The core component of the beam-scan detector is composed of 46 0.9-mm-thick LYSO (lutetium yttrium oxyorthosilicate) scintillators. The LYSO-scintillator array was equipped with a 46-channel silicon photodiode and current-mode signal processing electronics. The beam-scan detector was tested with 45-MeV proton beams provided by the MC50 proton cyclotron at the Korea Institute of Radiological and Medical Science (KIRAMS). This system has been shown to reliably detect and measure proton-beam profiles at currents ranging from 1 to 5 nA. We expect the current beam detector operating in the charge-integration mode to allow us to perform qualify measurements for therapeutic proton and heavy-ion beams.
