    Entry number 165093

    keyword=Moving beam DURING run 2624

    Beam was off for a while at the start of the run, and then the rates were much higher than when we ran on H2 earlier (HALOG 165701). So we're checking to see if it's better at the old beam position.

    Going back to the old x position (-1.0,-1.0) --> MUCH better rates.
    Going back to old y position (-1.1,-0.6) --> no real difference.
    Try moving x to (-1.2,-1.2) --> rates somewhat lower.

    We'll stay here, since the idea is to get clean data for big bite (drift chambers, I believe). Start up run 2625 with this beam position.

    (details on rates/positions in a seperate entry)
