Return to List of Daily Run Plans
Shift Duties
- Take Production data
- Log all issues, alarms and questions.
- Perform shift checklist.
- Log target status twice per shift.

VDC HV (both arms) | ON |
DVCS Calo HV | ON |
DVCS Kin_60_1
DVCS Calo Angle | 15.89° |
DVCS Calo Distance | 1.5 m |
LHRS Polarity | Negative |
LHRS Momentum | 3.594 GeV/c |
LHRS Angle | 24.564° |
LHRS Q1 Current | 749.67 Amps (regulator OFF) |
LHRS DAQ Config | DVCS |
prescaleL | PS9=1 (all others zero) |
GMp 4th Pass "Parasitic" Kinematics
RHRS Polarity | Negative |
RHRS Momentum | 1.804 GeV/c |
RHRS Angle | 53.475° |
RHRS DAQ Config | RHRSadaq2 |
prescaleR | PS1=PS2=PS3=1, && PS8=100 (all others zero) |
Compton runs
DVCS Trigger efficiency runs: instructions from Carlos
1) With the same CODA, target and beam configurations as production, bring the DVCS prescales GUI from adaq1 by typing: | prescale_DVCS | 2) Set the prescales as follows: | - 103kHz Clock: "Disabled" | - S0 & S2M: "1" | - S0 & CER: "Disabled" | - S2M & CER: "1" | Click the "Save" button to load the new settings. There is no need to restart or download the CODA configuration for these changes to be taken into account. | 3) Take a 15 min run. | 4) Set the prescales as follows: | - 103kHz Clock: "Disabled" | - S0 & S2M: "Disabled" | - S0 & CER: "1" | - S2M & CER: "Disabled" | Click the "Save" button to load the new settings. There is no need to restart or download the CODA configuration for these changes to be taken into account. | 5) Take a 15 min run | 6) Restore the production prescales: | - 103kHz Clock: "16384" | - S0 & S2M: "Disabled" | - S0 & CER: "Disabled" | - S2M & CER: "1" | Click the "Save" button to load the new settings. There is no need to restart or download the CODA configuration for these changes to be taken into account. | Exit the DVCS prescale GUI by cliking the "Exit" button | 7) Resume production... |
