Abstract:

The Compact Muon Solenoid (CMS) detector is described. The detector operates at the Large Hadron Collider (LHC) at CERN. It was conceived to study proton-proton (and lead-lead) collisions at a centre-of-mass energy of 14 TeV (5.5 TeV nucleon-nucleon) and at luminosities up to 1034cm -2s-1 (1027cm-2s-1). At the core of the CMS detector sits a high-magnetic-field and large-bore superconducting solenoid surrounding an all-silicon pixel and strip tracker, a lead-tungstate scintillating-crystals electromagnetic calorimeter, and a brass-scintillator sampling hadron calorimeter. The iron yoke of the flux-return is instrumented with four stations of muon detectors covering most of the 4π solid angle. Forward sampling calorimeters extend the pseudo-rapidity coverage to high values (|n | ≤ 5) assuring very good hermeticity. The overall dimensions of the CMS detector are a length of 21.6 m, a diameter of 14.6 m and a total weight of 12500t. © 2008 IOP Publishing Ltd and SISSA.

The MICE diffuser system

EPAC 2008 - Contributions to the Proceedings (2008) 2761-2763

Abstract:

The Muon Ionization Cooling Experiment (MICE) [1] at the Rutherford Appleton Laboratory [2] will measure the performance of a cooling channel in a variety of configurations of momentum and initial emittance. Coverage in emittance-momentum space relies on the MICE diffuser, a system with five different thickness lead degraders, remotely operated in a high magnetic field. Degrader optimisation for beam matching and technical issues are discussed.

Abstract:

This paper describes the evaporative system used to cool the silicon detector structures of the inner detector sub-detectors of the ATLAS experiment at the CERN Large Hadron Collider. The motivation for an evaporative system, its design and construction are discussed. In detail the particular requirements of the ATLAS inner detector, technical choices and the qualification and manufacture of final components are addressed. Finally results of initial operational tests are reported. Although the entire system described, the paper focuses on the on-detector aspects. Details of the evaporative cooling plant will be discussed elsewhere. © 2008 IOP Publishing Ltd and SISSA.
