Abstract
A new Compton polarimeter is built on the CEBAF Hall A electron beam line. Performances of 10% resolution and 1% calibration are required for the phot on calorimeter of this polarimeter. This calorimeter is built with lead tun gstate scintillators coming from the CMS electromagnetic calorimeter R&D. B eam tests of this detector have been made using the tagged photon beam line at MAMI, Mainz, and a resolution of 1.76%+2.75%/root E+0.41%/E has been me asured. (C) 2000 Elsevier Science B.V.
