MWGRs & CRUZET Analysis Merve Ince Emine Gurpinar Shuichi Kunori, Isa Dumanoglu Bayram Tali, Yalcin Guler, Serdal Damarseckin HCAL analysis Meeting 19. 03. 2015 1

Introduction • We have analyzed all CRUZET (23 February – 8 March, 2015) runs longer than 60 minutes. • We have used two different set of samples. – “/eos/cms/store/data/Commissioning 2015/Cosmics/RECO/Prompt. Reco-v 1” applying “L 1_Single. Mu. Open” trigger – “/eos/cms/store/data/Commissioning 2015/Minimum. Bias/RECO/Prompt. Reco -v 1/” applying “L 1_Single. Jet 16” and “L 1_Single. EG 5”. We will show 2 – Rec. Hit. Energy, ieta-iphi distributions and Calo. Jet. Energy for HB, HE, HO. •

Conclusion • We have checked the control plots (enerji, eta, phi vs. ) using the CRUZET runs (23 February – 8 March, 2015). • We compared MWGR 10 and CRUZET looking by Calojet enerji plots including HAD enerji, EM enerji distrubitions. We will add franction of them. • We report about some bad HBHE channels in MWGRs and CRUZET at Operation Meeting (16. 03. 2015) https: //indico. cern. ch/event/370930/contribution/3/material/slides/0. pdf • Most of individual channels in HB and HE are stable with rms ~ 0. 2 Ge. V and mean ~ 0. 15 Ge. V. • Some channels misbehave in ieta versus iphi plots for HBHE because of wrong pedestal used in the offline reconstruction ? ? (Ted’s comment) 22

Why does the CMS take Cosmic Runs? ? 31

§ Detecting cosmic rays need different techniques (synchronization, reconstruction, …) § Cosmic rays arrive at the detector at random time random direction. 32
