Table II.
Performance characteristics of PMTs evaluated. PMTs 1–5 were manufactured by Hamamatsu Photonics; PMT 6 was manufactured by Photonis. Performance characteristics of the Hamamatsu PMTs were measured and reported by the manufacturer [31], while the XP20D0 characteristics were measured and reported independently in [32]. PMTs bias voltages were set according to manufacturer’s recommendation.
