The inner tracker slow control system now has an automatic error recovery implemented. This does however not mean that no alarms occur. It means that inner tracker alarms are recovered by the internal error recovery system first.
The switching on of the Inner Tracker right now is safe. So
once "LUMINOSITY RUN" appears on the HERA monitor, switch the
inner tracker to "READY". The ITR is included in the
common slow control, just switch it on with everything else.
If you have any questions call
the inner tracker chamber
expert.
Remember that you will have to switch it off BEFORE the wires are
extracted.
If you don't understand any of the instuctions or don't know what to do
call the on call
expert
The inner tracker is switched off together with the all other detectors by
changing the state of the Central Slow Control (CSC) from "READY" to
"SAFE".
To see, if the detector is in the right state, check all inner tracker slow
control processes. If all are ON respectively READY-state and none are excluded
from control, the system is ready.
The Inner Tracker part of the "Process State Display" should look like this:
If you have further questions, call the on-call expert.
Check in the DQ histos in the global section of the histograms: There is a page with eight correlation plots the two on the right are showing the correlation between inner tracker and VDS (upper plot) and OTR (lower plot). If you see a correlation, the inner tracker is running synchronous.
The inner tracker has a number of DQ histogram in the DQ system that can be checked. Right now we are still waiting for the training to be finished, so that we can publish some reference histograms for the shift crew to compare. If you are in doubt about the quality of the data taken, please call the inner tracker expert.
If you feel it could adversely affect the quality of the data being taken, contact the on-call expert. In any case, send an e-mail to the responsible for this page.
