Last update on Aug. 18,1997 Hodoscopes and Cerenkov history ------------------------------- General information. 1) ADC gates: 135 ns. It applies to all the counters throughout the 1996-97 data taking. 2) TDC set: Number of TDC hit recorded: 3, bit resolution: 1 ns. These apply to all the counters throughout the 1996-97 data taking. Time window: a) from the start thru run 725: offset 0 ns, gate width 512 ns b) from run 726: offset 160 ns, gate width 300 ns. ====================== start of H1 ======================================= HV: from the very beginning of the run (9/30/96 run 276) values have never been changed. The values are listed here.
