Abstract :
We measured the analyzing power and the efficiency of a new neutron polarimeter that was designed to measure G
En, the neutron electric form factor. The polarimeter calibration was performed as experiment E377 at the Indiana University Cyclotron Facility (IUCF) with the
14C(p&oarr;,n&oarr;)
14N reaction at proton beam energies of 124.0, 164.6, and 199.7 MeV without any shielding material ahead of the polarimeter; in addition, at 164.6 MeV we measured the analyzing power
y> with 10 cm of lead, sandwiched between 3.5-cm iron plates, ahead of the polarimeter.
