From: A high sensitivity Cherenkov detector for prompt gamma timing and time imaging
TOF distributions obtained with the thick PMMA target and with detector A (in blue) placed at 157\(^{\circ }\) and detector B (in red) placed at 90\(^{\circ }\) from the beam direction. The relevant signal is in the region between 0.5 and 3 ns. Outside this region, the background is mainly due to random coincidences caused by the limited size of the beam monitor. The two bumps located at (−1.0 \(\div\) 0.5) ns and (2.9 \(\div\) 4.1) ns for detectors A and B distributions, respectively, are associated to protons scattered in the beam detector.
