Abstract

The proton gyromagnetic ratio (γ'_P) plays a fundamental role in achieving highly accurate magneticfield measurements. At the KRISS complex for the determination of the proton gyromagnetic ratio, we have improved a magnetic-field standard based on the value of γ'_P and related techniques. The standard for measuring DC magnetic flux density is intended to cover the range from 20 µT to 2.5 T, with an uncertainty ranging from 4·10^-6 to 6·10^-5 T.

Keywords
