A Beam–Beam Counter detector will be employed for local polarimetry and is based on plastic scintillator tiles with signal readout via wavelength-shifting optical fibers, coupled with silicon photomultipliers. The quality of the scintillator tiles directly affects the accuracy and stability of the detection system. We present a method for evaluating scintillator homogeneity, based on step-by-step scanning with a collimated X-ray beam using AMPTEK Mini-X X-ray tube with a silver target and a 2 mm circular collimator. The SiPM current response as a function of the X-ray-tube position was measured using the A7585D power supply with a microammeter, which is part of the CAEN DT5202 system. The data were used to construct response maps across the scintillator-tile surface and were analyzed using dedicated software.
