Description

Scintillating screens equipped with optical cameras are widely used in accelerator facilities for transverse beam profile monitoring, as this method is simple and precise compared to other beam diagnostics. However, the image sensor is sensitive to secondary radiation induced by the interaction between the particle beam and the scintillation screen. Radiation damage degrades the performance of image sensors by increasing hot and dead pixels, which poses a major hurdle for camera-based beam profile monitoring. To address this issue, we developed a radiation-tolerant beam viewer using a cooled CMOS camera. In this contribution, we present the radiation tolerance test results of the cooled CMOS camera and demonstrate the feasibility of this new radiation-tolerant beam viewer system.
