Abstract
Different support posts for the Large Hadron Collider (LHC) prototype superconducting magnets have been designed and manufactured. They have been evaluated both mechanically and thermally. The posts are made of a tubular section in composite materials, i.e. glass- or carbon-fibre and epoxy resin, with glued metallic heat intercepts and connections. Mechanical tests have been carried out with both radial and axial loads, before and after cooldown to working temperature. The design considerations and future developments concerning dimensions and other materials are also discussed in this paper. Thermal performance has been evaluated at 1.8 K, 5 K and 80 K in a precision heat leak measuring bench. The measurements have been carried out using calibrated thermal conductances (“heatmeters”) and boil-off methods. The measured performances of the posts have been compared with analytical predictions.
