The Hall-C Moller Polarimeter measures the polarization of the electron beam arriving in Hall-C. It does so by observing the rate of production of Moller electrons at 90 degrees in the center of mass when the beam strikes a thin iron target. The outer shell electrons in the iron are polarized parallel (or anti-parallel) to the beam direction by a 4 Tesla magnetic field. The Moller electron production rate differs when the beam and target electron spins are aligned parallel or anti-parallel to one-another. Measurement of this rate difference provides a measure of the beam polarization.

Project Progress Summary
10 July 1990
Injector & Front-End Test
-Injector tests during the past week have been fairly successful. We have delivered good beam to WBS 3 for their evaluation of the RF control system, and to WBS 5 for tests of the beam position monitors. Improvements to the control software have brought us to the point where setting up a good 5-MeV beam is (almost) routine. (C. Sinclair)
