keyword=EPR Measurement before Hall A accessCell: Maureen Oven Temperature: 230C Laser Power: 75 W(Comet 25Wx3) Target Position: He3 Field Direction: Transverse - NMR RF Field: Longitudinal NMR Pumping Chamber Pickup Coil: Vertical Pumping Direction: Anti-Parallel
First Measurement: Integration Gain: 1.6 Calibration Constant: 2.95 %/mV Polarization: 62.6%
Second Measurement: Integration Gain: 1.0 Calibration Constant: 2.92 %/mV Polarization: 59.7%
The second measurement clearly has a better lock and accuracy, so I put
that number to be our new calibration constant
