    keyword=Switch to LH2 target and 3uA beam

    Due to high dead time we currently taking data with only 2uA beam. I would like to switch to LH2 target and raise the beam current to 3uA. According to Friday swing shift experience the dead time will be around 17%. I am going to do that at the end of run 8733. Of course we will keep eyes on the dead time.

    My plan is that we keep taking data with LH2 and 3uA till Tuesday, when there will be a beam study. On the other hand, we will try to solve the dead time issue. Once this issue solved, we will run a few days with LD2 to compensate the statistics.
