4. Ursula Bassler, LPNHE Paris4Collaboration Meeting - 13 Sept. 2001 Pedestal Calibration  Tools being developed for calibration validation  Mrinmoy left  latest version delivered with many improvements, but not working correctly yet pedestal comparison between 2 calibration runs

5. Ursula Bassler, LPNHE Paris5Collaboration Meeting - 13 Sept. 2001 SCA-behavior  all faulty channels were changed for ICD ( ~ 15%)  bad SCA chips labeled for detailed studies at SUNY

6. Ursula Bassler, LPNHE Paris6Collaboration Meeting - 13 Sept. 2001 Pulser Calibration  measurement of pulse shape:  validation of signal simulation model  determination of optimal calibration timing for various channel types  linearity studies of gain paths:  linearity with respect to linear fit  preliminary studies at 0.2% level time (ns) ADC counts ADC (meas-fit/max) pulse height em channel pulse height ADC (meas-fit/max) gain x8 gain x1

8. Ursula Bassler, LPNHE Paris8Collaboration Meeting - 13 Sept. 2001 Hot Cell Killing  Hardware improvement: replacement of bad SCA-Cards  apply “Hot Cell Killer” on remaining bad channels  improvement of calibration validation procedure  online Hot Cell identification in CalExamine  database modification

9. Ursula Bassler, LPNHE Paris9Collaboration Meeting - 13 Sept. 2001 Trigger Studies  slow rise of trigger signal not understood  trigger threshold w.r.t. precision read- out:  2 difference  behavior of hadronic veto not clear  studies on signal shape in the electronics chain, understanding of ADC/GeV conversion w.r.t. trigger signal  L1 trigger Read Out needed

12. Ursula Bassler, LPNHE Paris12Collaboration Meeting - 13 Sept. 2001 Calorimeter Run Information This web page is for the use of shifters and experts for updating and viewing the Calorimeter Runs database. The database uses MS Access 2002. It is fully viewable and active IF you use MS Internet Explorer ver 5.5 or above. That means you are screwed if you use Netscape - sorry. The links at left will link you to various live database views: D0 Calorimeter Run Database Web  News - new developments and update  All Runs - A summary of fields for all runs in database  All Runs Day - A summary of fields for all runs sorted by day  All Runs Type - A summary of all fields for all runs sorted by run type  Static Database Reports - these reports are NOT dynamic, but need to be refreshed by hand to remain current, however they are visible to all.  Input Data - A page that takes you to the data input pages FOR EXPERTS ONLY \\D0server4\projects\CalorimeterElectronics\Tuts\Cal_Runs_Database\index.htm

13. Ursula Bassler, LPNHE Paris13Collaboration Meeting - 13 Sept. 2001 What can you do?  sign up for some shifts:  3 every month or two months will make a great difference for us!  non-experts are demanded!  look at the data:  feed-back for hot cells or dead regions, strange effects “useful run information” will depend on the input we get! some problems have been seen offline first!!  allows to develop better online tools  trigger debugging, efficiencies, turn on curves  studies related to the energy scale  help to develop tools  TASK LIST on commissioning web-page! Talk to Nirmalya, Andre, Lee or me!
