The Spin Physics Detector (SPD) is an experiment at NICA designed to study the spin structure of the proton and deuteron and other spin-related phenomena using polarized beams. Two Beam– Beam Counters (BBC) will be installed symmetrically aside from the interaction point in the end- cups of the SPD setup and will serve as a tool for beam diagnostics including local polarimetry. The outer part of the BBC wheel is based on fast scintillator tiles and covers the polar angles between 60 and 500 mrad. Different material configurations for the BBC prototype based on scintillator tiles were tested. The light collection depends on material combinations — fiber (Saint Gobain BCF91AS, BCF92S, and Kuraray Y-11), tile surface cover (matted and double covered with Tyvek sheets tiles), and optical cement (CKTN mark E, OK-72). SensL 1 × 1 mm and 3 × 3 mm SiPMs were used as photosensors in the prototype tiles. The studies were performed with a cosmic ray test setup equipped with CAEN FERS-5200 readout system.
