This Møller Polarimeter is used in Hall A of Jefferson Lab (former CEBAF) in order to measure the polarization of the electron beam. It consists of a polarized target, a magnetic channel consisting of 4 quadrupoles and one dipole and of a detector consists of a sandwich-type electromagnetic calorimeter and an aperture detector made of plastic scintillator.

This page resides in JLAB and is regularly updated. A good page on this polarimeter with a lot of details on the design is residing in University of Kentucky
