Nuclear-resonance magnetometer with flowing liquid for superstrong inhomogeneous fields measuring

Abstract

Multichannel nuclear-resonance magnetometer for remote monitoring of induction and heterogeneity of a magnetic field in different areas inside and near a charged particle accelerator is considered. The maximal distance between the nuclear magnetic resonance signal detector and the magnetometer is 50 m. Measurement error is 0.5%, sensitivity of the magnetometer is 10 −10 T/Hz 1/2 , measurement time of the magnetic field parameters in 24 control points is no more than 4 minutes.
