NMR signal to He3 polarization relation is calibrated by water cell test.

Introduction

Sept 28, 2008 measurement

Coil Position Survey

All error below is 65% CL static error

Up Stream:
Cell Diameter = 19.27 +/- 0.05 mm
Distance between 2 pick up coil inner surface : 21.31 +/- 0.14 mm
Cell to left Coil Inner Surface = 0.34 mm (Preliminary, could come with high Error)
Cell to right Coil Inner Surface = 1.70 mm (Preliminary, could come with high Error)


Down Stream:
Cell Diameter = 18.62 +/- 0.03 mm
Distance between 2 pick up coil inner surface : 20.87 +/- 0.07 mm
