    Entry number 168704

    keyword=EPR-NMR calibration

    Performed an NMR-EPR calibration at 13:30. The beam had been off of the target for 1/2 hour before we returned the target to the 3He position and took our calibration

    Results:

    First NMR

    UP x=129.4 y=4.165 R=129.5

    DOWN x=127.8 y=3.703 R=127.9

    Second NMR

    UP x=125.6 y=3.932 R=125.7

    DOWN x=124.4 y=3.508 R=124.4

    The EPR measurement give a magnetic field that is consistant with our previous measurements.

    First transition: \delta \nu = 57169 Hz

    Second transition: \delta \nu = 56752 Hz

    The ratios of lower/upper coils for the NMR sweeps: before EPR UP: 72.9 before EPR DOWN: 72.2 after EPR UP: 72.6 after EPR DOWN: 71.4
