    keyword=Target - EPRs at gradient coil current L=2.5A T=5.0A

    2:00am, set longitudinal gradient coil to 2.50 A
    overall conditions for EPR:
    cell position = pickup coil, 3 lasers on, grad coil current L=2.5A T=5.0A
    2:01am, EPR, freq 1/2 = 47.46/47.06 KHz, P1/2=46.49/46.09;
    2:10am, EPR, freq 1/2 = 46.87/46.89 KHz, P1/2=45.92/45.93;

    comments: did not observe masing.
