Second mock-up coil for the MQYY magnet after winding and polymerization. 

Tests being carried out on the superconducting power line. 

For the HL-LHC Collider-Experiment Interface Work Package, their LS3 started last January with the manoeuvres to remove the ATLAS end cup toroid (JTT) shielding (Image: F. Sanchez Galan, CERN). Full details in Accelerating News | Issue #28

The first TCLD collimator produced in industry arrived at CERN on January 30th. This is the first of four dispersion suppressor collimators that will be installed around IP2 and IP7 to improve the collimation performance. This is one of the first HL-LHC devices to see the LHC beams: installed in LS2, the TCLD will already be operational for the Run III from 2021. Around IR7, two TCLD will be installed together with the 11 T dipoles that will replace one LHC dipole per side.

Excavation of the two new shafts for the HL-LHC at points 1 and 5 of the accelerator has been completed, CERN Bulletin.

The WP8 team successfully extracted the JTT from the ATLAS detector on 11 January!

Tests carried out in 2018 on two crab cavities in the SPS validated their technical principle and many operating parameters, CERN Bulletin.
