- 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)
