• 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 -

• 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

• • 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
