    I do not get the comment on this-  could you elaborate -
    
    It is not obvious from logbook why system could not come back
    - my suspision is that the detectors tripped
    due to a large dose of beam (T2, T3,T4 T5 dump) and Brahvo program does not
    always
    handle trips nicely. I will like to remind shifters to pay particular
    attention to background rates
    and record these when un-usual events take place.

    That is pretty clear - I discussed with Ramiro and at an opening we will
    attempt
    to isolate the plane in question (need 1-2 hour at an appropriate time).
    Until then we will focus on physcis measurements where the DC's  are not
    needed.
