ABSTRACT
We built and operated a new kind of Compton polarimeter to measure the electron beam polarization of the Thomas Jefferson National Accelerator Facility (Virginia, USA) to 3% total error within an hour. The heart of this polarimeter is the coupling of a High Finesse monolithic Fabry-Pérot cavity to the particle accelerator. Its purpose is to amplify a primary 300 mW laser beam to increase the luminosity at the Compton interaction point. The measured Finesse and amplification gain of the cavity are F = 26000 and G = 7300. We have used this facility during the HAPPEX (April-July 1999) experiment.
