The design of an ultra light structure, the so-called “stave”, to support and cool the sensitive elements of the Barrel Pixel detector, the innermost part of the ATLAS detector to be installed on the ...new Large Hadron Collider at CERN (Geneva), is presented.
Very high-dimensional stability, minimization of the material and ability of operating 10 years in a high radiation environment are the key design requirements.
The proposed solution consists of a combination of different carbon-based materials (impregnated carbon–carbon, ultra high modulus carbon fibre composites) coupled to a thin aluminum tube to form a very light support with an integrated cooling channel.
Our design has proven to successfully fulfil the requirements. The extensive prototyping and testing program to fully qualify the design and release the production are discussed.

The Ring Imaging Cherenkov detectors of DELPHI represent a large-scale particle identification system which covers almost the full angular acceptance of DELPHI. The combination of liquid and gas ...radiators (C
4F
10, C
5F
12, and C
6F
14) provides particle identification over the whole secondary particle momentum spectrum at LEP I and LEP II. Continuing optimisation on the hardware as well as on the online and offline software level have resulted in a stable operation of the complete detector system for more than five years at full physics performance.
Nucl.Instrum.Meth.A531:481-514,2004 A full azimuthal phi-wedge of the ATLAS liquid argon end-cap calorimeter has
been exposed to beams of electrons, muons and pions in the energy range 6 GeV
<= E <= ...200 GeV at the CERN SPS. The angular region studied corresponds to the
ATLAS impact position around the pseudorapidity interval 1.6 < |eta| < 1.8. The
beam test set-up is described. A detailed study of the performance is given as
well as the related intercalibration constants obtained. Following the ATLAS
hadronic calibration proposal, a first study of the hadron calibration using a
weighting ansatz is presented. The results are compared to predictions from
Monte Carlo simulations, based on GEANT 3 and GEANT 4 models.
