The Compressed Baryonic Matter (CBM) experiment at the Facility for Antiproton and Ion Research (FAIR) in Darmstadt requires a highly accurate beam monitoring and time-zero (T0) system. This system needs to meet the requirements of the CBM time-of-flight (ToF) measurement system for both proton and heavy ion beams, while also serving as part of the fast beam abort system. To achieve these goals, a detector based on chemical vapor deposition (CVD) diamond technology has been proposed. In addition, new developments using Low Gain Avalanche Detectors (LGADs) are currently under evaluation. This contribution presents the current development status of the beam detector concept for the CBM experiment.

The KOMAC (Korea Multi-purpose Accelerator Complex) has operated 100-MeV proton linear accelerator and provide high flux proton beam at the TR103, a general purpose irradiation facility. To uniformly irradiate the sample with protons, it is important to confirm the beam profile uniformity through the quality assurance (QA) process. Recently, for real-time and in-situ proton beam profile monitoring at the TR103, P43 phosphor screen and TE-cooled CMOS camera were introduced and tested. The camera captured images of the emitted light as protons with energy of 15, 42, 100 MeV were incident. A software for selecting beam profile image and post-processing of image data such as background subtraction, image smoothing, geometrical correction, selecting Region Of Interest (ROI) and X-Y coordination was developed using Python. Measured beam profiles using phosphor screen and cooled camera were compared to Gafchromic film. The linearity between light output and beam flux were measured. In this study, we will discuss the test results of proton beam profile measurement using phosphor screen and TE-cooled CMOS camera for introduction to quality assurance process at the TR103.
