October 1, 2008 online meeting minutes

present: Sergey Boyarinov

• dvcs trigger

clean AC power for dvcs racks installed, power strips installed, will be connected as first occasion

all discriminators connected to TDCs, all cables checked and good; one trigger-related 34-pair cable seems bad, will be repaired

Ben prepared maps, need to incorporate them into existing map tables; DVCSTRIG firmware was modified to allow 4 reference signals into discriminators

new 34-pair cable was run between DVCSTRIG and CLASTRIG2 and new signal propagation measurements were conducted; results looks promising, we need to gain another 30-40 ns to be in time, one more please to look is the gate cables between clastrig2 rack and fastbus crates, they can be shorter, Chris is arranging new cables layout; forward carrage will be moved into final position soon and final measurements will be conducted then

software: both DVCSTRIG and CLASTRIG2 GUIs are operational, more tests will be performed; Ben provided header files so we can adjust our scripts and EPICS, work is in progress

Pawel is working on lookup table procedures

other activity discussed on previous meetings still to me conducted: need some trigger logic test; Hovanes may need to modify EPICS GUIs, Sergey B. need to fix EPICS stuff
