July 2, 2008 online meeting minutes

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

EC: gamma (EC mip)

     gamma(EC) x gamma(EC) (2 sectors)

     e (ECmipxCC)

     h+- (ECmipxTOF)

IC threshold will be 300-500MeV

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 ?)
