Abstract :
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.
igh-dimensional stability, minimization of the material and ability of operating 10 years in a high radiation environment are the key design requirements.
oposed 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.
sign has proven to successfully fulfil the requirements. The extensive prototyping and testing program to fully qualify the design and release the production are discussed.
