keyword=EPR Calibration @ Transverse PumpingAfter changing to EPR pumping, an EPR measurement if performed:
D2 Output : ~-30mV
RF Amp : -10 dB
Gain : 0.9
Int Gain : 1.7
3 EPR FM sweep resonance is observed. The K39 resonance is screen shot
below. Then there was an successful EPR AFP sweep, which showed that
Pol. = 28.2%
An NMR field sweep is followed, which give a 13mV NMR signal from
Vertical Pickup Coil. So calibration constant is
Pol. = 2.17%/mV * Vertical pickup NMR @ empty target position
