?Development of Gas Scintillation detector for high intensity proton beam
- ?We developed a beam monitoring system by using gas scintillator for high intensity proton beam which will be provided by Korea Multipurpose Accelerator (KOMAC) user beam line. The KOMAC proton beam makes pulsed beam with very high beam current. In this case, we faced on the several problems, such as pileup and saturation of signals, with ionization chambers or crystal scintillation detectors. Moreover, some detectors could be damaged by the high dose radiation environment. Gas scintillation has a lot of advantages to overcome these problems. It has not only very fast response (few ns range), but also strong radiation hardness. We used Ar for gas scintillation monitoring detector and test it at the KIRAMS (Korea Institute of Radiological & Medical Sciences). The detector showed reasonable performance and proton beam bunch structure was observed.
