    Entry number 158799

    keyword=MCC called: compton lock was OFF; we request compton lock ON

    at 0428, MCC informed us that the "compton lock" is OFF and asked us if we wanted it ON. we weren't sure if we wanted it ON or OFF b/c the Compton people had just done a vertical scan during day shift and presumably had everything just as they like it.

    however, according to the compton data taking guide, the compton lock "is a slow feed-back on the vertical beam position in the compton chicane" and should be ON.

    since compton run 12627 was almost over, we decided to let it finish with the compton lock OFF.

    at 0447, we asked MCC to turn the compton lock ON. at 0450, MCC called back saying that they had done so and subsequently we started compton run 12628.
