    keyword=HV problems

    at 22:05 the GUI for the HV gave an alarm and only showed empty boxes
    T1 and T2 were close to 0 (0hz/10hz), counting rate around 30, high deadtime (15%)
    reset of Lecroy HV IOC did not help
    on the portserverscreens on adaql2 , one screen showed HV off
    switching it on again: normal trigger rates
    so we continued in data taking
    still no output of the HV with the GUI
