    keyword=Target: EPR/NMR calibrations for Dolly

    Around 2000 hrs we did an EPR-NMR calibration. Two-coil NMR followed by two EPRS followed by another two-coil NMR. We used the 85Rb resonance for EPR. Here are the results:

    first NMR : x/up = 76.46 mV; x/dn = 76.16 mV

    first EPR : 32.57% falling edge; 31.45% rising edge second EPR : 31.998% falling edge; 30.56% rising edge

    second NMR : x/up = 74.23 mV; x/dn = 73.44 mV

    These give calibration constants as: (%/mV) 0.431, 0.411 (last sweep) 0.428, 0.411 (first sweep)

    Avg: 0.4203 %/mV

    Average polarization now: 31.5% (EPR)
