Beam loss detection is essential for the machine protection and the fine tuning of the accelerator to reduce the induced radioactivity. The beam loss monitors (BLM) at the China Spallation Neutron Source (CSNS) are mainly divided into the following types: the coaxial cylindrical ionization chamber (IC) filled with Ar/N2 gas mixture, Xe, BF3 gas, and the scintillator with photomul-tipliers, among which the Ar/N2 IC is the main type. In the low-energy section of the linac (beam energy <20 MeV), the BF3 BLMs enclosed by a high-density poly-ethylene (HDPE) moderator are utilized to detect the beam losses. The Monte Carlo program FLUKA is employed to perform the relevant simulations. This paper presents the summary of the beamloss detection for the CSNS BLM system.
