Owl Shift, Monday, August 26, 2002 Aram. Dan S. Dan D./Eric Dave 00:00 Bruno, Dan & David still in hall. 12:25 we figured out relative negative number moves tac beam right, positive-- beam left (units on expert gui are centimeters). absolut position of TAC center is x=18.373 12:30 Dan, Dave and Bruno are out from hall, we asked for 100pA beam. 12:50 we have 100 pA beam 01:00 TAC trips, we asked for 80 pA beam 01:10 putting radiator C in. 01:30 looked at relative timeing of triggers(MOR & TAC), MOR is coming 100ns later need to add delay cables to TAC in order to have MOR gate in time TAC ADC signals 01:40 asked for controled access to add delay cables 02:00 people are back from hall waiting for a beam at the same time short test run(only TAC trigger) with no beam 02:45 tagger harp scan gui failed 02:55 run #775 TAC in, beam current 70 pA, no radiator C in, no converter run ended with about 1 000 000 events 03:20 run #776 TAC in, beam current 80 pA, radiator A in, 5% converter in MOR prescale 100, TAC prescale 1000 03:50 run #778 TAC out, beam current 80pA 04:05 run#779 TAC out, beam current 230pA, PS trigger prescale 300, MOR trigger prescale 25. 05:20 run#784 100nA, PS trigger prescaled 30000, MOR trigger run ended with about 1 000 000 events (need to change TAGE LIFO depth) 05:40 run#787 100nA, TAGE LIFO depth changed from 15 to 8, beam triped for short time, lost beam for about 20 minutes. just got a call from MCC there is some kind of phase drift problem in the machine and to correct that they would need to go tune beam mode and they are not authorized to do so(they been told by P.D. not to) So I assume we will not have beam for at least a couple of hours.
