Shift Duties
- Take Production data
- Log all issues, alarms and questions.
- Perform shift checklist.
- Log target status twice per shift.

Beam Energy | 8.5 GeV |
Target | LH2 (Loop 2) |
Raster | ON (2x2mm2) [MCC units h=2, w=3] |
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... |
