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.

The WP8 team successfully extracted the JTT from the ATLAS detector on 11 January!
A 'loaded' start to the year for HiLumi. Before the JTT extraction next week in the ATLAS cavern, a WP8 team performs load tests (18.4 tons) in the SX1.

During a public visit, the HL-LHC collaborators saw the progress on the civil engineering works, where in that moment the excavations had reached 30 metres at Point 1 and 25 metres at Point 5, Accelerating News | Issue #27.

The beam screen for the High-Luminosity LHC will be installed by 2024 in the aperture of the inner triplet superconducting magnets near ATLAS and CMS, CERN Updates.
After having undergone several high intensity beam impacts at the HiRadMat facility in August, the TDIS HRMT-45 module was disassembled in November by the EN/STI-TCD and EN/SMM-MRO teams in the bunker 867-R-P58 for the post-irradiation analysis. The ultimate goal is to verify that all the equipment components remain fully functional after the high thermomechanical loads they were subjected to during the experiment. Such loads were equivalent to those likely to occur inside the TDIS during future operation with HiLumi beams. Given the significant radioactivity of the module, some dismantling activities are to be performed by means of robots in order to minimize the dose taken by personnel. The robot appearing in the picture is the in-house developed CERNbot, which was able to unfasten the tank upstream and downstream transitions while being operated remotely from another room. This was possible partly thanks to some robot-friendly solutions implemented in the TDIS HRMT-45 design agreed with MRO. The next step following to the tank opening is the metrology of the jaws, which flatness level measurement is expected to return similar values with respect to the pre-test condition. More pictures are available in CDS.
Developed as an upgrade of the current TDI (target dump injection) located at point 2 and point 8 of the accelerator, the TDIS will provide a higher intensity absorption capability for the High-Luminosity LHC, CERN News.
The HL-LHC annual meeting, held on 15 October, had a particular significance this year: we’re halfway between the beginning of the project in 2010 and the scheduled start-up of the machine for physics in 2026..., CERN Opinion.
