CERN Accelerating science

A word from the Deputy Head of the EP department - December 2021

Welcome to this year’s final issue of our EP Newsletter, featuring a series of stimulating articles on a wide range of activities across the department. After almost three years of intense maintenance and consolidation, and several months of preparation the first pilot beams were injected into the LHC earlier on the morning of 27th of October. Read the brief stories from the control rooms of the major LHC experiments, discussing the value of the pilot beams and the challenges of restarting these complex systems.

The sight of the first test beams validates the upgrade work undertaken by the collaborations and sets the LHC experiments on course for Run 3 and the collection of more data to continue the exploration. In the issue you can also read about ongoing and planned upgrades of the LHC experiments including an article for the installation of a new GEM at CMS, progress with the installation of the VELO in LHCb. Furthermore, as the LHC experiments prepare to address the challenges of future runs of the LHC you can learn more about ATLAS plans for a new High-Granularity Timing Detector and ALICE proposed ITS3 upgrade.

Beyond LHC, this year has also been busy for the fixed target experiments. In this issue you can find a detailed discussion of the NA62 detector upgrades preparing to fully exploit its potential during the 2022 data-taking, as well as the gearing up of activities in the North Area and upgrade work for the ND280 detector that will be shipped to J-PARC facility in Japan and become part of the upgraded T2K later in 2022. 

Following the cautious reopening of activities and easing on travel restrictions, 2021 allowed for more meetings in hybrid format. Learn more about the discussions that took  place during the recent General Meeting of the Physics Beyond Collider group and the progress on both the experimental and accelerator fronts. A recent workshop at CERN focused on the intriguing flavour anomalies following the recent announcements by the LHCb experiment at CERN and the g-2 experiment at Fermilab. Moreover, the 5th PHYSTAT workshop brought together different communities to address key topics and develop new tools needed for future analyses in particle physics. Finally, 2021 has been a busy year for detector R&D activities with a wealth of results presented during the EP R&D days as well as the preparation of ECFA’s future roadmap also presented/covered in this issue.

As ever, in this issue, there is something for everyone to explore over the holiday season. Wishing you all the happiness your holiday can hold. We hope you and your families have a safe and relaxing holiday season and we are looking ahead to an even more inspiring new year.
