- dvcs trigger
racks will be in final destination today
all discriminators have test inputs connected ( 6 groups 5-6 boards each), signals looks fine; width must be more then 25ns, otherwise built-in scalers can miss them (40ns will be fine)
one pulser (from FC)
measure cables to test inputs of discriminators, then run existing 34-pair cable from SF to FC and look signals at CLAS trigger module and in ADCs, then decide on desired length of 34-pair cable and run it when FC is in normal position; propagation through detectors still must be estimated
software: GUI is done, under testing, plan test for Friday; scripts and EPICS TO BE ADJUSTED; need some trigger logic test; need to make sure everybody have the same map, ADC and TDC and trigger; Pawel will prepare lookuptable procedures; Hovanes may need to modify EPICS GUIs, Sergey B. need to fix EPICS stuff
- adcs/tdcs/scalers
mini-VME64X borrowed from Chris and installed in the rack with splitters; mvme6100 CPU, TI and 4 v1190 TDC boards are installed; may need DAQ scalers, for example OR outputs from discriminators
CC1 and EC2 swapped contents; CC1 has IC and Hodoscope ADCs (8 total); gate signals to be swapped
