    keyword=Compton elec. det.

    Took 45 min of beam time around 4pm for the commissioning of the Compton electron detector.
    Although we started with a nice flat tune in the straight hall A beam line, very large vertical offsets (>5mm) were observed after turning On the Compton dipoles.
    When in beam position the electron detector trips the eP ion chamber.
    Vertical correctors were used to correct the positions but didn't allow the electron detector to be set in beam position.
