    keyword=Target polarization

    Steffen checked the polarization for the transverse pumping after 14 uA beam on.
    Study shows that there is a difference in the measured polarization with lasers off and
    with lasers on. The measured polarization with lasers off is about 31% and with lasers on is about 33% (using 2.6 %/mv). The difference is due to the temperature change.
    The measurement with lasers on should be the number to be compared with the longitudinal case. So the conclusion is that it has about the same polarization as in the longitudinal case (about 33% with 14 uA beam).
