The HL-LHC magnets and cold powering systems are planned to be tested individually on dedicated test benches in the SM18 test facility at CERN or at the collaborators test facility (e.g. at Fermilab in the USA).

The 2018 Chamonix workshop featured three sessions for the HL-LHC project. The sessions at Chamonix provided the first chance for a technical and performance review of the project following the re-baselining in 2016.

The 3rd Cost & Schedule Review of the projects HL-LHC and LIU was held at CERN on 26th – 28th of March 2018. As usual, the panel is composed by the CMAC (CERN Machine Advisory Committee) members with the addition of a few other international experts

The construction of the 5.5-m long 11T dipole prototype was completed in May this year after several years of intense work dedicated to the development and optimisation of the special tooling, and of the related manufacturing and inspection procedures.

Two contracts for the civil engineering works were adjudicated by the Finance Committee of March 2018 to a consortium MARTI TUNNELBAU, MARTI ÖSTERREICH and MARTI DEUTSCHLAND for the Point 1 works

Following the re-baselining exercise for the HL-LHC project in June 2016, the HL-LHC project implemented several scope changes ith respect to the PDR that was issued at the end of the EU funded HiLumi Design Study.
