50. Measuring the Neutron-to-Mercury Gyromagnetic Ratio and Investigating nEDM Systematics

Wenting Chen (PSI - Paul Scherrer Institut)

Oral Presentation

on behalf of the nEDM collaboration

Understanding the spin-precession behavior of ultracold neutrons and cohabiting mercury atoms in a magnetic field is essential for the neutron EDM analysis. In this work, we present an improved determination of the neutron-to-mercury gyromagnetic ratio using the n2EDM apparatus at PSI. A global-fit method is applied to investigate gravitational frequency...

46. LANL nEDM Double Arm Neutron Simultaneous Spin Analyzers

Katherine Zine (University of Illinois Urbana-Champaign)

Oral Presentation

Two double armed spin analyzers (DSAs) will be used for the Neutron Electric Dipole (nEDM) experiment at Los Alamos National Laboratory (LANL). These DSAs are meant to count the populations of high and low field seeking neutrons at the end of the experiment in order to calculate whether an nEDM is seen. Each arm will count a different population of neutron (i.e. high-field seeking vs low-field...

14. Performance of a new UCN detector developed for the TUCAN EDM Experiment.

TUSHAR TUSHAR (University of Manitoba)

Oral Presentation

The TRIUMF Ultra Cold Advanced Neutron (TUCAN) Collaboration has commissioned a new spallation-driven ultra cold neutron (UCN) source that provides unprecedented UCN density for conducting the next generation of precision nEDM measurements. A UCN Detector System capable of efficient operation at high UCN flux and with low backgrounds will be important for completing this precision...
