Cg. Kim et al., LOW-FIELD METHOD FOR MEASURING PROTON GYROMAGNETIC RATIO, IEEE transactions on instrumentation and measurement, 44(2), 1995, pp. 484-487
A measurement of the proton gyromagnetic ratio in water by the low-fie
ld method is in progress. The earth's magnetic field is compensated do
wn to 1 nT at the center of Helmholtz coils in the constructed nonmagn
etic facilities. The solenoid former of fused silica has been fabricat
ed by the screw grinding and lapping within the dimensional variations
of a few micrometers.
