How to verify the BCM trends:

1. Navigate to the FSM node ALI_DCS\LHC\DCS_BCM\BCM_TELL1\myTell1_BCM ( A) and double click on it to open the panel: . Open the "Sensors" ( B) tab. Use four buttons ( C) to display the BCM trends one by one.

  • For the RS32 trends: check if there is a peak of values on the plots that exceed the level of 20 nA (you should see a peak like D which corresponds to the time of the dump). Note the values of peaks

  • For the RS2 trends: check if there is a peak of values on the plots that exceed the level of 1000 nA. Note the values of peaks.

2.

  • If there is NO peak above 20nA on the RS32 plots and NO peak above 1000nA on the RS2 plots and ALICE dumped the beam (the beam permit was removed) then write an email to alice-dcs-support.PNG
  • If there is a peak above 20nA on RS32 plots OR a peak above 1000nA on RS2 and the beam permit was NOT removed then write an email to alice-dcs-support.PNG.

3. Note in the shift report the values of the all the peaks.

4. Change the panel (do not keep open the ALI_DCS\LHC\DCS_BCM\BCM_TELL1\myTell1_BCM -> Sensors panel - see Known Issues section in TWIKI Hot Topics)
