When you start your Operation Manager task
-- Add your name and contact informations to all the different expert lists (IFR, IR2 ...).
-- Subscribe to IFR-ops and Det-ops HyperNews
-- Check your safety training and JHAM status with Henry Band. If needed attend safety orientation, courses, etc...
-- Learn the babarifr account password
-- Add your e-mail address to the .forward file in ~babarifr (don't move or rename the file, just edit it).
Detector status (daily)
-- Click on the LV button in the IFR detector control panel. All
the power supplies should be green.
-- Check the LV currents and voltages in the summary page with reference
values in the IFR Epics panel.
- You can find
here typical readings
-- Click on the HV button in the IFR detector control panel. All
the crates should be green.
-- Check that all channels are connected except for the masked ones in
this page .
-- Check in the Configuration Panel that the HV settings correspond
to the ones of the reference.
-- Click on the Gas and Gas interlock buttons in the IFR
detector control panel. Checks for differences with reference values.
-- Click on the Gas interlock button in the IFR detector control
panel and check for SIAM trips
4.Bubblers status for Fwd Endcap:
-- Click on the Dbubl button in the IFR detector control panel.
Checks for differences in Fwd Endcap East, West and Belt with reference values.
-- Check for new channels that are dropped near to 0
-- Click on the Chillers button in the IFR detector control panel.
-- Check that everything is green.
-- If something is red, click on SIAM ctl button
and note which interlock channels show problem
6. Check the Trigger Status
-- Click on the Trigger button in the IFR detector control panel
-- Check if some readings are 0
7. Check the DAQ and I/O crates
-- In the IFR_ODC main page the contours of the IFR-Mon, IFR-HV and FEE-DAQ buttons should be green.
-- If not, click on the buttons to look for the problem.
8. Check the IFR Archiv Status
-- Click on the Archiv button in the main
-- Check that the number of channels alive and the number of channels configured
is the same for the IFR. If not report the difference configured-alive
-- Check if the time of the last flush is within aproximately an hour for
-- Check if IFR is alive (last column)
History plots (twice a week)
1.History plot of the ratio of dark current over single rate for Forward
-- Check any departure from a flat history over the time in
Fwd Endcap East and
Fwd Endcap West .
2. Silent and Hot FECs from offline
-- You find this informations in the summary of the FEC status updated for every new run.
-- In pages 1-3 you can find the number of silent/hot FECs compared to 1, 10 and 50 runs ago
-- In pages 6-9 you find these numbers for the last 200 runs compared to a series of reference runs (straight lines)
-- In pages 10-13 these numbers are plotted again without comparison
If you think you have found new silent or hot FECs:
-- Look at last file in the directory /nfs/bbr-nfs03/detector/ifr/calib/central/ps/.
The last calibration should be more or less 24 hours old.
-- Histograms on page 17 give you the number of hot/dead FECs:
blue top histogram -> silent/dead FECs
red bottom histogram -> hot FECs
-- The response of every single FEC is plotted in the green histograms in the previous pages. Check for silent
or hot chains (large areas of 8 bins empty or too high).
3. Check Efficiency history:
Check any departure from a flat history over time in the IFR
4. Check Bubbler history:
Check any departure from a flat history (gas leak) or crazy behaviour (electronic reading problem) over time in the
REMEMBER: Whenever if you find anything out of normal or you have any question,
inform the Operations Manager.
