In spite of the perturbation related to the COVID-19 pandemic, the civil engineering works is progressing well.

The HL-LHC IT String is a major, intermediate milestone for the HL-LHC project ahead of the installation of the first cold powering systems in the LHC tunnel during LS3.

The 8th Beam Gas Curtain (BGC) Collaboration Meeting was held at CERN in early April.

This collaboration concerns the cryostat devices that will house and connect the HTS REBCO current leads to the MgB2 Superconducting Links powering the HL-LHC magnets.

The HL-LHC WP5 activities started in LS2 with some important upgrades in preparation to the full deployment of HL-LHC in LS3.

In the framework of HL-LHC AUP in the US, last year two prototype RF Dipole Crab Cavities manufactured in Italy by Zanon Research & Innovation were validated successfully at FNAL through cold tests at 2K.

CERN, STFC Daresbury Laboratory (STFC-DL) and Lancaster University have collaboratively designed a pre-series cryomodule to house 2 “RF Dipole” type Crab Cavities, with the aim of assembling the module at Daresbury Laboratory and testing at CERN in 2023.

The magnet program has reached several milestones since the last annual meeting: in the following we summarize the main achievements of our collaborations.

In May 2022, HL-LHC AUP project successfully completed an endurance test on an individual magnet (MQXFA05) in vertical position.

The HL-LHC Project is entering the series construction phase and therefore most of the collaboration agreements are now focused on the production of final elements that will have their destination in the LHC tunnel and in the set of operational spares.
