From Hall A Wiki
- Updates
- hodoscope
- working on pathlength correction
- values for RF timing bunch number, check with Mark
- Provokar looked at RF timing , there is an EPICS variable which might have RF bunch - Sebastian
- HCal
- Sebastian met with Mark and Maria for RF time, looked at plots paddle vs RF
- GRINCH
- 8 ns structure still puzzle
- GRINCH using VETROC, need to correct with trigger time - Might need TI trigger correction -
- hodoscope
- HCal timing
- Sebastian looked at FADC time : include time walk, TOF, trigger jitter, best cluster selection
- timewalk not applied to FADC data
- TOF from MC
- trigger jitter : FADC - hodoscope
- wide cut on adctime 5 sigma
- need physics module
- from highest energy block from cluster
- timing improves with amplitude ?
- possible improvement -
- Victoria will look at intrisic timing resolution with tdc and fadc
- Sebastian looked at FADC time : include time walk, TOF, trigger jitter, best cluster selection
- SBS firmware developement : Ben could start working on some SBS developement
- Hydra : need to generate pictures and do training
- CCDB and RCDB : setup locally on laptop, seems to work , need to insert data to test
- missing TDC HCAL study
- low amplitude less than 10 mV are missing
- check width from discriminator - 50 ns expected - checked a few channels - 1 channel with 20 ns and 3 have 40 ns - one channel gives 80 ns if signal big -
- check bandwidth of discriminator
- data missing large amplitude signal missing - could be because of width
- look at FADC signal for missing TDC high signal -study from Sebastian
- missing TDC HCAL study
