Trigger efficiency
- Gas Cerenkov efficiency - 3 % inefficency - Accuracy of measurement
- S2m efficiency - Some paddles were less efficient - Shift of one S2m paddle ( pedestal update )
- Analysis of single arm data
Normalization/deadtime
- logic module output
- logic module bit patterm
- scalers
- bit pattern TDC working
- Random trigger understood ?
Helicity
- Ring buffer errors - recoverable ?
DAQ
- Buffering seems to work - Sync ADC deployed - Would like access to add the VME ADC front end busy, need ECL cable, NIM fan. Crate synchronzation seems ok so far.
- additionnal sync signal in ARS
- ARS spares
- Pedestal noise issues seems by Ben - Is it in the data ?
- Full setup in DAQ room
- Calibration of trigger module failed , reason still unclear - Missing Mezannine board
- Add multiple triggers ?
Run list
- How much data was taken ? Data quality
Low current vs high current
Calorimeter
- calibration : pi0 ( Eric out of town )
- radiation damage
BCM calibration

continue Kin3 4 pass until VME320 work
switch to Kin 2 low to test VME320 with H and D, low current, high current, buffered and unbuffered ( might be ready tomorrow or Wednesday )
Trigger ( still not clear how long it will take, Ben will start looking at the code maybe tomorrow , rough estimate one week)
in parallel full setup in DAQ room for logic module check.
single arm data with trigger readout to check trigger efficiency
try coincidence ( middle of Kin2 H or D )
pass change ( 3 pass or 5 pass ? )
- complete Kin I low and optics data
Go to 5 back to 5 pass ?
