A gaseous-helium cooling system for silicon detectors in the Nab experiment
Love Richburg, Noah Birge, Nadia Fomin +40
The Nab experiment aims to extract the neutron beta decay correlation coefficients 'a' and 'b'. This will be accomplished using a 7 m tall electromagnetic spectrometer which measur…

A Novel, Steerable, Low-Energy Proton Source for Detector Characterization
Nicholas Macsai, August Mendelsohn, David Harrison +7
We report on the conversion of the Manitoba II mass spectrometer into a versatile low-energy proton beam facility. This infrastructure is adaptable to any detector-under-test (DUT)…

A Method for Proton Detector Efficiency Measurement with Applications in Neutron Beta Decay and Lifetime Experiments
Grant V. Riley, Nadia Fomin, Jaideep Taggart Singh +4
This article proposes a new method to measure the proton detector efficiency for use in "beam" determinations of the free neutron lifetime. There is currently a 4σ disagreement bet…
