Towards the challenging Dynamic Aperture goals of Run 4
The recent IPAC’23 conference was an ideal opportunity to present and discuss within our community the status of the beam dynamics simulations for Run 4, marking the start of HL-LHC operation. At top energy, proton beams will circulate in the machine for about 10 hours, covering inside the LHC ring about half the distance of…

Access conditions to new HL-LHC galleries during Run3
This year, it will finally become possible to descend to the underground areas of the HL-LHC by lift, at Point 5 before the summer season and at Point 1 in November. From these dates onwards, different teams will enter these areas on a regular basis to commence the installation of technical services such as lighting…

WP3 contribution
INFN collaboration: High order correctors and D2 recombination dipole The last batch of the 54 high order corrector magnets was successfully tested in LASA by the end of 2022, and all correctors have been delivered at CERN. In February 2023, a celebration was held to mark the end of the first series production of HL-LHC…

Status of infrastructure installations for HL-LHC
Following the handover of the civil engineering buildings and structures in the period from May 2020 until January 2023, the installation of the general services and technical infrastructures has started at the HL-LHC worksites of P1 (ATLAS) and P5 (CMS). The two worksites are in the so-called worksite Category 1 and will remain closed and…

Crystal collimation for the operational ion run in 2023
While the HL-LHC era for proton collisions starts in 2029 with the operational Run 4, the aim is to achieve the target HL heavy-ion performance already in Run 3 following the upgrade of the ALICE experiment during LS2. Thanks to the LHC injector upgrade program successfully completed during LS2, and in particular due to the…

HL-LHC IT String advances
As highlighted in the latest report on the HL-LHC IT String, the installation and operation of this test stand marks a very significant milestone for the High Luminosity LHC (HL-LHC) project. Most of the state-of-the-art technologies developed within the scope of the project will prove that they can effectively work in harmony, simulating diverse operational…

Assembly of RFD crab cavity module for delivery to CERN in September
The Cavity-String beamline and Fundamental Power Couplers were assembled in the ISO4 cleanroom jointly with STFC and CERN staff. After the successful leak check of the beam vacuum, RF checks and the final alignment, the cavity string was moved to the cryostat assembly area and is currently being equipped with the tuning system and RF…

Update on the HL-LHC Project Status
The project reached several key milestones since the last Newsletter. Among the many achievements I would like to highlight here the celebration for the completion of all Civil Engineering work in January at CERN. The new underground structures have been completed by the end of 2022 and the new surface buildings at P1 and P5…

Start of Series production of DFHX/M by RFR
The HL-LHC Cold Powering Systems transfer the current from the power converters, located in the new underground galleries, to the superconducting magnets of the HL-LHC Inner Triplets and Matching Sections at Point 1 and Point 5. Eight systems of two different types will be installed in the HL-LHC underground as from mid-2027. Each of these…

Planning of the CSR’23
The now annual Cost & Schedule review 2023 will take place between the 13th and the 17th of November. As requested by the ATS management, this will be an extended edition, alternating with the ‘light’ version held in 2022. This year, most work-packages will be asked to present their budget, schedule, and changes therein, as…
