IIHE Tracker DQM meeting - Friday 04/09/2009
========================
Minutes by Pascal
Tracker DQM for Muon HLT
------------------------
ACTION: Volker starts to work with Muon HLT expert (Jean-Roch Vlimant)
and Eric during the Bologna physics week to understand what is needed
from the Muon HLT side. To be understood first:
- what kind of tests should be run to make a diagnostic of the
tracker performance when the Muon HLT does not work well
- what kind of data can be used to test the tests: CRAFT ?
Simulated events ?
Quality Test (QT) tuning
------------------------
Nikita showed the change in expected average occupancy per module
with jet events (QCD pThat 80-120 at 10 TeV c.m. energy). The change in occupancy
reflects the detector geometry, but does not give a clue of the occupancy
in early beam conditions (beam-gas interactions, minimum bias events).
Also, the use of the QT flag is unclear: is it meant to automatically flag
noisy runs, or is it only a help for online shifters ?
ACTION: Pascal writes a mail to Suchandra and the tracker DPG conveners
(Didier Contardo and Thomas Speer) to better define the aim of this work.
Depending on the outcome of this discussion, more or less manpower from IIHE
will be devoted to this topic.
Timing of DQM modules
---------------------
This task consists in evaluating the time taken by the Tracker DQM modules
in order to evaluate the rate of events that can be logged online.
Gregory will be at CERN for 1 month from September 7 with 1 week break
(see availability table). Gregory will follow up this task from
Brussels afterwards.
Offline run certification
-------------------------
Otman, as offline shift leader, is validating the run quality
manually by looking at a number of histograms. It appears that
good scripts existed, initially developped by Volker, that
allowed this validation to be done automatically. By lack
of manpower, the scripts are not maintained anymore.
ACTION: Volker proposes to Suchandra, Didier and Thomas
that the IIHE takes over the update and maintainance
of these scripts, that would save a lot of time of
the offline shiftees and be an objective test rather
than a subjective judgment of the shiftee.
This work package would be taken in charge by Otman
and would be worth 6 weeks of service.
Work organisation and stays at CERN
-----------------------------------
According to the progress done, Volker calls for reports from people of the IIHE team
at the relevant Tracker DQM and Tracker DPG meetings.
Eric will go to CERN from September 20 until October 30.
Alexis and Vincent will go to CERN from September 28 until October 30.
Thierry will go to CERN as soon as possible and stay until October 30.
ACTION: Volker will set up an availability table on the web, to ease
the management of the group which is fairly large and where people
will move a lot.
ACTION: Pascal books the flats.
Dates of next meetings
-------------------------------
The IIHE tracker DQM working group will meet weekly on wednesdays 10h30-12h30. Next meeting will be the week after the CMS physics week in Bologna.
There are minutes attached to this event.
Show them.
