Description

The Hybrid Laser Accelerator for Radiobiological Applications (LhARA) is designed as an innovative, flexible, and low-cost facility dedicated to the systematic study of the radiobiological effects of particle beam therapy. Capable of delivering instantaneous dose rates that not only reach but also surpass the conventional “FLASH” regime with ultra-high dose rate.
However, monitoring such intense, rapid-pulse beams requires radiation-resistant detection technologies. This work presents a comprehensive simulation study evaluating the response of a special type of low-gain avalanche detector (LGAD) to the LhARA proton beamline.
We present the results of our Monte Carlo simulation combined with a Technology Computer-Aided Design simulation of the irradiation of the LGAD detector with ultra-high dose rate, the simulation results indicate the potential feasibility of using LGAD technology for dosimetry in the environment of the LhARA beamline. This study establishes an essential foundation for future experimental validation and optimization of next-generation beam monitoring instrumentation.
