    keyword=Ice in acceptance (?) & Collimator check

    I went into Hall A to check if everything was okay with the collimators. They appears to be fine.
    I also check for ice. I found some that was possibly getting into the acceptance. However it is difficult to say. See fig for a drawing of the ice. The measurements put in the fig are VERY ROUGH since it is very delicate to put any instrument there.
    I removed entirely the ice.
    I noticed also that the ice was not on the green foam but on the black insulant surrounding the septum entrance.

    We should check for ice from time to time.
