List of tasks:

    Test beam calibration and on-line monitoring.

  1. Develop methods how to calibrate modules of HCAL(+ECAL) at the beam. - A.Gribouchine, A.Erchov, V.Kolosov
  2. Establish the scale in 'GeV' for each calorimeter cell (ECAL+HCAL+HF). - A.Krokhotine, A.Oulianov
  3. Creation and maintenance of dynamical database with calibration coefficients used for online calibration.- A.Oulianov
  4. Slow control e.g. monitoring of signal from HF (LED/LASER/Source). Control for the variation of calibration constants due to radiation damage. - A.Gribouchine, A.Erchov
  5. Monitoring of radiation fields using signal from radiation monitors - A.Gribouchine, A.Erchov
  6. Program support of geometry and calibration database for off-line reconstruction:

  7. Model of radiation damages (HF/HE) - A.Gribouchine, A.Erchov
  8. Update of HF geometry in CMSIM - V.Kolosov
  9. Creation and maintenance of the database with calibration constants in ORCA.- A.Oulianov
  10. Algorithms development for calibration and monitoring in situ:

  11. Develop algorithms to do calibration using benchmark processes (gamma+jets, Z+jets, isol pi etc.) - I.Vardanian, O.Kodolova, I.Lokhtin
  12. Develop algorithm for pile-up subtraction (event by event) - I.Vardanian, O.Kodolova
  13. The study of a possibility to use the radial Et distribution inside jet at L1 trigger. - A.Krokhotine
  14. Jet and MET energy scale correction in dependence from the type of the object or process. - A.Krokhotine.
  15. Determine the set of calibration constants for L1. - A.Krokhotine
  16. Optimization of weights (k1,k2) in k1*ECAL+k2*HCAL weighted sum to improve jet energy resolution - A.Oulianov
  17. Monitoring of variation of calibration constants using pile-up events. In particular based on the fact that average response of Ķells having one and the same eta have to be equal. - S.Petrouchanko, K.Teplov
