Interior Vector Magnetic Field Monitoring via External Measurements for the SNS Neutron EDM Experiment

ORAL

Abstract

A prototype of a magnetic field monitoring system designed to reconstruct the vector magnetic field components (and, hence, all nine of the $\partial B_i/\partial x_j$ field gradients) within the interior measurement fiducial volume solely from external measurements is under development for the SNS neutron EDM experiment. A first-generation room-temperature prototype array has already been tested. A second-generation prototype array consisting of $12$ cryogenic-compatible fluxgate magnetometer probes will be deployed within the cold region of the experiment's $1/3$-scale cryogenic magnet testing apparatus. We will report progress towards the development of this second-generation prototype.
