Characteristics of a double gap resistive plate chamber for the endcap region of CMS/LHC : Data vs simulation in avalanche mode / Ahn, S H ; Bahk, S Y ; Hong, B ; Hong, S J ; Kang, D H ; Kang, T I ; Kim, K H ; Kim, T J ; Kim, Y J ; Kim, Y U et al.
We present the detailed analysis of the time and charge signals of a prototype double gap resistive plate chamber for the endcap region of the compact muon solenoid detector at CERN LHC. We demonstrate that the operating high-voltage plateau can be extended at least up to 400 V with the present design. [...]

Readout and control of optical alignment devices in the ATLAS muon endcap / Rothberg, Joseph E
Optical devices have been used to monitor the positions and deformations of the ATLAS Endcap Muon chambers in real-time during data-taking in a muon beam at CERN. A part of an octant of the ATLAS Muon endcap spectrometer has been set up in a test beam to study particle tracking precision. [...]

The CMS crystal calorimeter / Lustermann, W
The measurement of the energy of electrons and photons with very high accuracy is of primary importance far the study of many physics processes at the Large Hadron Collider (LHC), in particular for the search of the Higgs Boson. The CMS experiment will use a crystal calorimeter with pointing geometry, almost covering 4p, as it offers a very good energy resolution. [...]
