A new neutron polarimeter and measurement of GnE from the 2H(e↘,e′n↘)1H reaction

In a continuing effort to improve the quality of measurements for extracting the neutron electronic form factor (GnE) from the 2H (e↘,e′n↘)1H reaction, one of us (RM) proposed a new configuration for a neutron polarimeter (NPOL) to measure GnE from the 2H (e↘,e′n↘)1H reaction in Bates E89‐04 and CEBAF E93‐038. Substantially higher count rates with this new neutron polarimeter reduce the uncertainties in GnE. A description of the new NPOL is given here followed by an outline of the experiment with projections of uncertainties in GnE.
