• FT - Ben

• FTOF - Sergey, Ben

• stage2, stage 3 - Ben

3. Simulation:

• GEMC fadc mode1 digitization - Rafo

• stage 1 (except FT) - Sergey

• stage 1 (FT) - Andrea

• stage2, stage 3 - Rafo

• validation 1 (cosmic vs C++) - Sergey, Rafo

• validation 2 (GEMC vs C++ vs CLARA) - detector groups ? ( Cole, ..)

• geometrical match tables - Andrea

4. Configuration:

• trigger config files, configuration manual - Ben, Sergey

5. Monitoring:

• trigger results in data stream - Sergey

• histogramming, messaging, EPICS - ?

6. Cosmic commissioning (with plan) - Ben, Sergey, Cole, ...

7. Beam commissioning plan (starting configuration, parameters to be changed etc) - Valery, ...

Progress since last meeting:

• 12 VTP boards installed in Hall (Ben, Sergey): 10 in DC and 2 in FTOF sectors 5 and 6. Five more VTPs needs repair - in progress. Cabling under way, should be mostly ready in few days, but new fiber trunk installation may take 2 weeks - not enough ports on SF (Chris, Mark, Armen). All VTP installation may take couple of weeks because of needed repairs.

• HTCC from GEMC is included into trigger validation (Rafo, Sergey), we have now PCAL, ECAL and HTCC, FT (Andrea) and FTOF(Sergey) are in progress.

• Andrea sent first version of FTOF-PCAL geometry table, PCAL-ECAL to go

Ben's presentation on trigger stage2/3

stage 2 timing diagram and FT/HODO

to do

• monitoring screens - epics_server-URGENT

• GUI - Valery will provide layout

• evio banks decoding - Gagik, Andrey Kim

• beam commissioning plan - Valery

• next week turn everything installed on

• HTCC trigger will be modified: 36bit mask -> 48bit mask
