Revision as of 08:46, 18 October 2010
Status :
- Top crate works ok
- move to other crate improved : can take full calorimeter data
- trigger read out, firmware being checked - test during access
Issues :
- ARS empty FIFO message and synchronization [[1]]
- data still shifts in the buffer
- ARS initialization - not clear if we start shifted by one
- spares : no spare left - one crashing - one loosing synch
Requirements for production :
- now
- check ARS mapping with calorimeter
- Dead time calculation
- sync check
- helicity
- ARS trigger efficiency - data taking efficiency
- calorimeter calibration
- short term
- trigger
- logic module with triggers and bit pattern, on board scaler for dead time
Data to be analyzed :
- elastic data
- sync data
- optics data
- BCM calibration
- Pion rejector calibration
Possible plan :
- During access :
- check trigger
- test sync checks, scalers, dead time
- trigger power cycling
- EPICS crate - HV cratea power cycling
- ARS mapping check with LED
- continue elastic calibration Monday owl, update ARS firmware , Tuesday, Wednesday - trigger commissioning
- polarity change Thursday - take DVCS production single and coincidence - check consistency between S2 trigger and S2 trigger in logic module - Question stay at 5 pass or go to lower pass ?
