Revision as of 10:32, 2 July 2008
present: Sergey Boyarinov, Pawel Turinski, Hovanes, Stepan, Sergey, Ben, Valery
1. one e in CLAS (ECxCC)
2. one pi0 (2 gammas) DVCS 2 clusters standalone
3. neutral trigger (2., or one in IC, one in CLAS)
4. one e in DVCS x Hodoscope [x something in CLAS, if rate too high]
Logic:
IC: gamma (IC only, or HbarxIC)
e (IC only, or HxIC)
multiplicity (one cluster, two clusters, ... - need more outputs)
cluster identification algorithm (central tower, 3x3 window with any number of towers etc)
EC: gamma (EC mip)
gamma(EC) x gamma(EC) (2 sectors)
e (ECmipxCC)
h+- (ECmipxTOF)
IC threshold will be 300-500MeVas ADC value, we'll have discriminators so it will be amplitude, not charge
Q: how far lvds signal can be send ? we need at least 4 outputs from HxIC logic (2 for ICxH and 2 for IC)
Q: do we need HbarxIC ?
Q: cluster finding algorithm in IC (high thres and one tower, or low thres and cluster ?)
Q: trigger timing ?????
Schedule: Ben may start in 2 weeks, will ask Chris if it is possible; we'll finilize our requirements during those 2 weeks;
system must be ready by the end of August; old CLAS L1 trigger logic can be removed if reproduced in new system without losing and functionality
