Pixels of cross-section 2 × 2mm2 or 3 × 3mm2 and length of 3 or 10mm were coupled to Hamamatsu SiPM and read out by fast high-frequency electronics. Materials whose timing performance relies on Cherenkov emission, namely BGSO, PWO, and PbF2, achieved time resolutions in the range 24–36 ps. Scintillators as L(Y)SO:Ce, GAGG, and BaF2 reached below 15 ps, the best topping at 12.1 ± 0.4 ps. These fast materials are compared to LYSO and their additional benefit is discussed. Given the promising results of BaF2, the study is completed with measurements of the scintillation properties of a set doped with yttrium to quench the slow light emission.
