Description
"In the framework of the High Luminosity – Large Hadron Collider (HL-LHC) project, the
accelerator’s collimation system will be upgraded. Thirty-six new collimators of 5
different designs will be produced in industry, including units of completely new
designs, as well as replacements for existing collimators and spares. The production of
these collimators is taking place in two stages: starting with a pre-series of three units,
to validate the production of the 33 series units (second stage). This paper describes
the production and testing process of the three pre-series collimators, from the
production of the collimator jaws, through vacuum vessel manufacturing and collimator
assembly, to delivery at CERN. It details relevant production methods, including
electron beam welding, vacuum brazing and bending of cooling pipes. The extensive
testing campaign carried out on the pre-series units is described, including both Quality
Assurance tests at the contractor’s premises during production as well as the Site
Acceptance Test campaign taking place at CERN upon reception of the collimators. The
goal is to validate both the collimator functionality and the contractor’s production capabilities.
