Tender requirements change V. Kulikovskiy

Tender vs Tests at Dark. Box Tender Acceptance test Prepulses between -100 ns and -10 ns: 1% max. Delayed pulses Early after-pulses between 10 ns and 60 ns (i. e. pulse arriving late with no pulse at correct time): 3. 5% max. between 10 ns and 100 ns: 2% max. (-60 ns; -10 ns) AVG 0. 05%, more than the 80% under 1% between 15 ns and 60 ns 5. 5% max AVG 3. 75%, more than the 80% under 3. 5% Not measured Late after-pulses between 100 ns and 10 us: 10% max. Dark counts at 20 deg C and 0. 3 spe threshold within 12 hours Between 100 ns and 10 us AVG 12. 5%, more than the 80% under 10% PMT and the rates are monitored for 9 hours. The mean dark count rate is computed by an average over the last 100 s of the run. More than 80% under 2 kcps
