    Entry number 44089


    keyword=target status changed

    During a beam trip, something happened and the temperature started rising too much so it was necessary to open the JT valve to a value of 40.46.
    Unfortunately this made the pressure sensor PT83 read 51.8, so I had to change the HIGH limit back to 52.00.

    As the target was stable before with a HP heater value of ~40kW and a beam of 71uA, and as it is stable again now, with the same values of HP heater and beam current, I cannot explain such a change in the JT valve value.
