Description

Beam loss monitor (BLM) is a key device for protecting accelerator systems, as it measures secondary radiation produced by a particle beam colliding with the inner wall of the accelerator. Therefore, in the KOMAC 100 MeV proton accelerator, BLMs were installed on the 20 MeV DTL (Drift Tube Linac) and 100 MeV DTL tanks for the purpose of machine protection. These BLMs are scintillator-based radiation detectors capable of operating in high-radiation environments, with two or more devices installed on each DTL tank. In this study, the nonlinearity between BLM signal intensity and beam loss was analyzed to demonstrate that considering not only beam current but also other conditions are essential for calibrating BLMs.
