- CPP and NPP Run Conditions
- Electron beam energy expected = 11.7 GeV based on the planned Experimental Schedule
- Microscope will cover the range of [0.301-0.514] of the beam energy or [4.57-6.01 GeV]
- Pair Spectrometer magnet will be scaled down by 6/9 = 0.67 of its nominal field (569.4 A = 0.67x849.9 A)
| Activity | Duration (PAC Days) | Current | Target | Collimator | Radiator | Comment |
|---|---|---|---|---|---|---|
| Full target (Production) | 20 | 27 nA | Pb (0.3 mm) | 3.4 mm | JD70-103 or JD70-107 | Alternate 0/90 deg diamond configuration |
| Empty Target | 1.5? | 27 nA | - | 3.4 mm | JD70-103 or JD70-107 | Run at higher current? |
| Diamond Alignment | 0.5? | 20 nA? | Pb (0.3 mm) | 3.4 mm | JD70-103 and JD70-107 | |
| Trigger Commissioning | 1.3? | 100 nA? | Pb (0.3 mm) | 3.4 mm | JD70-103 or JD70-107 | |
| Lead Shield Alignment | 0.1? | 100 nA? | Pb (0.3 mm) | 3.4 mm | JD70-103 or JD70-107 | |
| Beam Energy Calibration | 0.1? | 100 nA | Pb (0.3 mm) | 3.4 mm | JD70-103 or JD70-107 | Collimator Blocking for 5 min, periodically |
| TAC Runs | 1.5? | <2 nA | - | 3.4 mm | AMO (2x10-5) |
Draft Commissioning Steps
- Setup photon beam operation at 50 nA.
