Some bad HBHE channels in CRUZET Runs Merve Ince Shuichi Kunori, Isa Dumanoglu Bayram Tali, Yalcin Guler, Serdal Damarseckin, Emine Gurpinar 1 HCAL analysis Meeting

We have analyzed some CRUZET (23 February – 8 March, 2015) runs longer than 10 hours. We have used only one data sample “/eos/cms/store/data/Commissioning2015/MinimumBias/RECO/PromptReco -v1/” applying “L1_SingleJet16”. We are investigate the bad HBHE channels looking at run by run for CRUZET runs.(for 6 runs which more than 10 hours) 2 Introduction

Run Information for CRUZET 3

4 ieta vs iphi in GeV for HB Run Run Run Run Run Run HB(ieta= -4,-9, -11, -14, iphi=2) Ieta= 15, 16, iphi=46 Ieta= 15, 16, iphi30 Ieta= 15, 16, iphi=26 Ieta= -14, -15, iphi=27 Ieta= 15, 16, iphi=46 Ieta= -14, -15, iphi=27 Ieta= 15, 16, iphi30 Ieta= 15, 16, iphi=26

5 ieta vs iphi in GeV for HE Run Run Run Run Run Run Ieta= -15, -16, iphi=50 Ieta=-15, -16, iphi=54 (ieta=16, 17, iphi31) Ieta= -15, -16, iphi=50 Ieta=-15, -16, iphi=54 (ieta=20, iphi21)

Conclusion 8 We have investigated misbehaviour channels using the CRUZET. Run by run are analyzed and channels are listed here: Most of channels in HB and HE are stable with rms ~ 0.2 GeV and mean ~ 0.15 GeV. Some channels in ieta versus iphi plots for HBHE have wrong pedestal used in the offline reconstruction HE channels ietaiphi HB channels ietaiphi HB channels ietaiphi

To do lists: We would like to check also bad channels depending on depth for HE and HB We will send mail to Salavat and Umesh to inform with regard to bad channels. CRAFT runs were taken between 12, March and 30 March, 2015 so they need to be analyzed and presented for next meeting. Comments and suggestions are welcome 9
