AbstractWe present an upgraded beam monitoring system designed for use in high-radiation environments where conventional imaging solutions rapidly degrade. In the presented device the radiation-sensitive P47 phosphor screen of the previous system* is replaced with a radiation-hard Chromox ceramic scintillator and relocates the CMOS camera outside the irradiation zone by transmitting the optical signal through a 20-meter radiation-tolerant fiber optic bundle. To enhance operational flexibility, a pneumatic actuator enables remote insertion and retraction of the scintillating screen into the beam path. The radiation hardness of the Chromox ceramic and the fiber bundle was evaluated, and the optical system’s resolution and fidelity were characterized. The new setup demonstrated stable imaging performance under irradiation, addressing the frequent maintenance issues of the previous system. These improvements offer a robust and low-maintenance solution for beam profile monitoring in demanding accelerator environments.
