Presentation Transcript

  1. ECAL H4 TB 2006 Status report Vladlen Timciuc, Caltech CMS Group

  2. Overview • Software framework • Analysis and preliminary results • To do list Vladlen Timciuc, Caltech CMS Group

  3. Software framework • CMSSW • CMSSW Tutorial • http://caltechcms.wikispaces.com/space/showimage/20060428-CMSSWTutorial.ppt • CMS Software Page • http://cmsdoc.cern.ch/cms/cpt/Software/html/General/ • In WebCVS subsection one can find complete overview of software classes. Vladlen Timciuc, Caltech CMS Group

  4. Software framework • ECALTBH4_0_1_0 – is the official CMSSW release for H4 TB. • Description of release as well how to install it can be found here: • https://twiki.cern.ch/twiki/bin/view/CMS/ECALTBH4 • Some ECALTBH4_0_1_0 tips: • https://twiki.cern.ch/twiki/bin/view/CMS/ECALTBH4Tips Vladlen Timciuc, Caltech CMS Group

  5. Wikipage • I created a small wikipage for ECAL H4 TB 2006. • http://caltechcms.wikispaces.com/ • By far it contains the information mentioned in previous slides. • I plan to make an eLog on this page. Vladlen Timciuc, Caltech CMS Group

  6. Analysis and Preliminary Results • I am working with simulated data. • Data simulated by Patrick Jarry for crystal # 1104. • Energies: 10, 20, 30, 50, 80, 120, 150, 180, 250 GeV. • Data contains 10k events per energy. • Hodoscope ±3 mm. (x-y). • Files can be found from your lxplus account at: castor:/castor/cern.ch/user/j/jarry/Simulation_1104/ Vladlen Timciuc, Caltech CMS Group

  7. Analysis and Preliminary Results • Reconstruction is done in ECALTBH4_0_1_0 • Weight method is used for reconstruction of the amplitude of the signal. • Analysis: • Look for the crystal with the highest energy deposit. • Fit energy distribution for 5x5 crystals around that crystal. • Double fit with Gauss, first to get approximate sigma and mean, second fit within range +2sigma -1sigma from previous fit mean. • Get energy resolution Sigma/Mean. • Do it for all listed energies.

  15. To Do List • Check the gain switch for reconstruction algorithm. • Receive resolution curve and fit it. • Perform the same for 3x3 and 1x1. • Try to apply different energy resolution fit procedure. • Try to reconstruct and analyze TB Data for SM22. • Perform again resolution task with simulated data for another crystal with different hodoscope cuts.
