    keyword=Target Vacuum Much Better with Beam

    The target vacuum level seems to recover pretty well once we get beam. My fear is that as we thermal cycle we begin to make some leak worse, which seals again when we heat the target can up. My conclusion is: don't stop running 50uA production on lead until the end of the experiment.
