The response of the CMS barrel calorimeter (electromagnetic plus hadronic) to hadrons, electrons and muons over a wide momentum range from 2 to 350 GeV/c has been measured. To our knowledge, this is the widest range of momenta in which any calorimeter system has been studied. These tests, carried out at the H2 beam-line at CERN, provide a wealth of information, especially at low energies. The analysis of the differences in calorimeter response to charged pions, kaons, protons and antiprotons and a detailed discussion of the underlying phenomena are presented. We also show techniques that apply corrections to the signals from the considerably different electromagnetic (EB) and hadronic (HB) barrel calorimeters in reconstructing the energies of hadrons. Above 5 GeV/c, these corrections improve the energy resolution of the combined system where the stochastic term equals 84.7±1.6% and the constant term is 7.4±0.8%. The corrected mean response remains constant within 1.3% rms. Abstract.

CMS Technical Design Report for the Phase 1 Upgrade of the Hadron Calorimeter

This report describes the technical design and outlines the expected performance of the Phase 1 Upgrade of the CMS Hadron Calorimeters. The upgrade is designed to improve the performance of the calorimeters at high luminosity with large numbers of pileup events by increasing the depth-segmentation of the calorimeter and providing new capabilities for anomalous background rejection. The photodetectors of the CMS Barrel and Endcap Hadron Calorimeters, currently hybrid photodiodes (HPDs), will be replaced by silicon photomultiplier (SiPM) devices. The single-channel phototubes of the Forward Hadron Calorimeter will be replaced by multi-anode phototubes operated in a dual-anode configuration. The readout electronics for all three calorimeter systems will also be replaced. A new charge-integrating ADC, the QIE10, with an integrated TDC will be used along with a 4.8 Gbps data-link. The off-detector electronics will also be substantially upgraded to handle higher data volumes and improve the information sent to the calorimeter trigger system. The expected performance of these upgrades is discussed, including a detailed study of several Higgs and SUSY analyses. The planning for the implementation of this upgrade is presented, including construction, testing, and installation. AcknowledgmentsWe would like to thank the technical staff from the various institutions for the design, R&D and testing of the many components of this upgrade.We also wish to thank the LHCC for their oversight and crucial advice during the development of the HCAL Phase 1 upgrade project. We also acknowledge the warm support received from the CMS management team. The important feedback from following CMS internal reviewers greatly helped in the development of this technical design report: Finally, we dedicate this technical design report for the phase 1 upgrade of the HCAL subdetectors to the memory of our colleague
