A new neutron polarimeter and measurement of {sup n}{sub E} from the {sup 2}H(e [downward right arrow] e' n [downward right arrow]){sup 1}H reaction

In a continuing effort to improve the quality of measurements for extracting the neutron electronic form factor (G{sup n}{sub E} from the {sup 2}H[downward right arrow]e'n[downward right arrow]) {sup 1}H reaction, one of us (RM) proposed a new configuration for a neutron polarimeter (NPOL) to measure G{sup n}{sub E}from the {sup 2}H (e[downward right arrow], e'n[downward right arrow]){sup 1}H reaction in Bates E89-04 and CEBAF E93-038. Substantially higher count rates with this new neutron polarimeter reduce the uncertainties in G{sup n}{sub E}. A description of the new NPOL is given here followed by an outline of the experiment with projections of uncertainties in G{sup n}{sub E}.
