A SQUID magnetometry system for a cryogenic neutron electric dipole moment experiment

Abstract:

Precision magnetometry is an essential component of any neutron electric dipole moment experiment in order to correct shifts in the neutron precession frequency due to changes in the magnetic field. We have developed a magnetometry system using 12 SQUID sensors, designed to operate in 0.5 K superfluid helium. The pick-up loops located near the neutron cell are connected to the SQUID sensors by ~2 m twisted wire pairs. The SQUID readout cables are run via an intermediate stage at 4.2 K. The sy...
