Nab Magnet Installed

Nab setup at SNS
Nab magnet installed at the FnPB at SNS
The Nab experiment is the next experiment to run on the Fundamental Neutron Physics Beamline (FnPB) at the Spallation Neutron Source. The experiment will make precise measurements of the angular correlation between neutron beta-decay products, and the beta energy spectrum, both stringent tests of the Standard Model of Particle Physics. The Nab magnet (7m long, superconducting, 4T maximum field) passed all acceptance tests and has been installed the SNS target hall. Installation of shielding (radiation and magnetic), access platforms and utilities is underway.
