keyword=NMR Frequency/Field Sweep Cross Calibration for Vertical PumpingA Frequency/Field Sweep Cross Calibration was performed for vertical
pumping. However, a glitch occurred before we rotated the field back to
vertical direction. Therefore the second NMR frequency sweep results has
quite large polarization loss compared to the first one and not reliable.
We will try to another one at a later time.
12:21 NMR Frequency Sweep@He3, Vertical+ Field, NMR Amplitude:
28.17(27.54)mV -> Polarization: 68.31(66.78)%
12:46 NMR Field Sweep@Pickup Coil, Longitudinal+ Field, NMR Amplitude:
286.5+284 mV -> Polarization: 69.60%
12:48 A small glitch occurred.
13:11 NMR Frequency Sweep@He3, Vertical+ Field, NMR Amplitude:
24.95(24.33)mV -> Polarization: 60.50(59.00)%
