• HV recovery channel L2.C.HVREC (e-log, e-log)
  Tripped three times. First, i0 increased to first 90uA, then to 100uA and then moved to v1 = 8500V instead of 9000V.
  
  
• ADC board Y_2904_X7_C2/H1/br02/crate0/slot08 (e-log)
  Stopped working on 16/08, then power cycled by Stelian on 20/08, now has stopped working again since 24/08. This time, to be replaced.
  
  
• HV channel BML.B.09.CO.Ly1 (e-log)
  Increasing channel current. All gas gaps moving, Icalib not set properly. Icalib moved to 300uA and i0 to 280uA.
  BML1A09.CO.DP2.Ly1.DZ1 gas gap driving ~50uA.
