    keyword=Compton Polarimeter

    Took some data for the Compton polarimeter.
    Need to go to very low threshold because of the 1.1 GeV beam energy.
    Signal/Bkg level in the photon detector occurs to be quite good (see compton spectrum below). Beam optics is good enough for Compton polarimetry.
    Polarization "estimate" not available yet because of software problem to read the helicity signal.
