Dec 2017
- Dec 7 2017 : NIM modules for setting the pulse width of S1X,S1Y,S2X and S2Y before the HODO 3/4 trigger changed to 758 from 752 in SHMS and HMS Log Entry
- Dec 8 2017 : HMS/SHMS HODO thresholds at 30mV. Log Entry
- Dec 8 2017 : Oscilliscope pictures of HMS trigger using EDTM Log Entry
- Note that this quickly changed and use later pictures.
- Dec 8 2017 : Oscilliscope pictures of SHMS trigger using EDTM Log Entry
- Note that this quickly changed and use later pictures.
- Dec 12 2017 : Oscilliscope pictures of HMS trigger using beam. Log Entry
- In HMS HODO 3of4 S1X is now sets the timing. All widths are 50ns.
- In HMS EL_LO which is a 2/3 from PR_LO,STOF and HODO 3of4, the STOF sets the timing.
- All other signal widths at 50ns.
- Dec 19 2017 : Oscilliscope pictures of SHMS trigger using beam. Log Entry
- In SHMS HODO 3of4 S1X is now sets the timing. All widths are 100ns.
- In SHMS EL_LO which is a 2/3 from PR_LO,STOF and HODO 3of4, the STOF sets the timing.
- All other signal widths at 50ns.
- Dec 21 2017 : Oscilliscope pictures of SHMS/HMS coincidence using beam. Log Entry
- Signal widths at 50ns.
- HMS sets timing.
- Elastic data with SHMS p = -1.816, theta = 25.01 and HMS p = +0.957, theta = 53.3
Jan-July 2018
- Jan 15 2018: Shift the STOF by 15ns in the SHMS and HMS EL_LO triggers. Log Entry
- Jan 18 2018 : Adjusted HMS timing in the coincidence trigger for having both spectrometers with beta near 1. Log Entry
- Oscilliscope picture of trigger. Log Entry
- Jan 23 2018 : Removed the HMS STOF from reference time singal. Log Entry
Aug 2018 =
- Aug 9 2018 : Removed El_CLEAN from SHMS/HMS reference time Log Entry
