Uncovering the fundamental laws and constituents of the universe is not just a source of fascination for particle physicists. Engineers, chemists and materials scientists draw similar motivation in meeting the challenging and strange requirements of cutting-edge accelerator and detector technologies. The interdisciplinary materials, metrology and non-destructive testing section at CERN supports projects such as the HL-LHC magnet development with state of-the-art equipment and analysis, and its services are increasingly in demand from projects outside – including the ITER fusion experiment (p37).
Also explored in depth in this issue are the next steps for the AWAKE plasma-wakefield experiment (p25), the new-physics implications of neutrino masses (p29) and a lesser-known approach to quantum gravity called asymptotic safety (p43). Advanced triggers for the HL-LHC experiments (p8), the selection of the SHiP experiment for CERN’s North Area (p7) and DESI’s first cosmology results (p11) are among other highlights, along with the latest LHC results (p15), conference reports (p19), news in brief (p13), opinion (p49), reviews (p52), careers (p55) and more.
anschaef Mon, 05/13/2024 - 12:49 Publication Date Mon, 05/13/2024 - 12:46Following damages caused by a car accident on 10 April, the opening hours of Entrance C (Route Maxwell, on the Meyrin site) had been adapted in the past weeks, and the presence of a security guard was required.
Unfortunately, the repair requires parts that will take 13 weeks to arrive. As a result, Entrance C will be inaccessible to incoming vehicles as of Monday, 13 May 2024.
Entrance C remains open for outgoing vehicles during the usual hours from 7 a.m. to 8 p.m., and for pedestrians and bicycles 24/7.
The SCE and EN departments thank you for your understanding.

katebrad Wed, 05/08/2024 - 10:37 Publication Date Wed, 05/08/2024 - 12:48The central heating at the Meyrin and Prévessin sites is usually turned off around mid- to late May each year. Reducing the number of days of heating on campus was one of the measures included in CERN’s Energy Savings campaign launched in 2022.
In line with the Organization’s long-term strategy for sustainability and its energy-saving policy, it has been decided to turn the heating on and off according to the weather forecast instead of a defined regular calendar.
The weather forecast this year, particularly the overnight temperature, allows us to turn off the central heating on 7 May.

The CERN Relay Race, organised by the Running club and the Staff Association, is back on Thursday 30 May for its 52nd edition.
The main race will start at 12:15 in front of Building 40, closely followed by the walkers’ race and the kids’ race, organised with the support of the Jardin des Particules.
Just like last year, the CERN Alumni network will be part of the event with their online relay race challenge: teams composed of CERN alumni from across the globe will be able to run the CERN Relay Race distances in their different locations.
Various CERN clubs will be presenting their activities and there will be a professional DJ to liven up the event. As always, runners are more than welcome to participate in fancy dress and compete in the costume contest.
Registrations open on 1 May on the CERN Running club webpage (you can also scan the QR code on the poster).
Let’s beat last year’s record in terms of participants: 156 teams and over 1000 runners and walkers in total!

katebrad Fri, 04/26/2024 - 18:33 Publication Date Mon, 04/29/2024 - 12:58The LHC Early Career Mentoring Committee and CERN’s Women in Technology group have teamed up to launch a new and unique mentoring programme: Mentoring@CERN.
The pilot phase of this initiative, which aims to promote professional development and support within the CERN community, is set to commence on 15 April.
Who can participate?
If you're associated with CERN through a contract, whether as staff, fellow, student, user, PART, or external contractor, you're eligible to join. You don't have to work for the LHC experiments or be a woman to take part.
There are no age or career level restrictions, ensuring that anyone can apply to be a mentor or mentee. We carefully pair mentors and mentees on a case-by-case basis with personalised matches.
Timeline for 2024
Registration for the pilot round opens on Monday 15 April 2024 and closes on Wednesday 15 May. By the end of May, you'll receive news about your match.
A kick-off meeting will take place in June, where we will share more information about mentoring best practices and helpful tools to jumpstart your mentorship experience.
How to participate?
Applying here will take less than 5 minutes.
Simply fill out the registration forms for mentors and/or mentees and attach your CV and a short cover letter. Your application will be carefully reviewed to find the perfect match for you.
Behind the scenes
The WIT mentoring programme, established in 2018, focused on pairing mentors and mentees with a special emphasis on female mentees. Meanwhile, the LHC Early Career Mentoring Programme, launched in 2020, connected mentors and mentees working on various LHC experiments.
Inspired by our shared vision, we are combining forces to merge the programmes, uniting our strengths to provide mentorship opportunities to the whole CERN community.
Information session
Whether you want to share your expertise or seek guidance to navigate your career path, we hope Mentoring@CERN will offer a unique experience.
If you are not sure what the programme can provide or if have questions you would like to ask, we invite you to attend our information session on 25 April at 12:30 CET: https://indico.cern.ch/event/1403801/

Taking part is easy: first form a team of four, give your team a name and register it on the Bike to Work website. No team? No problem: you can also request to join an incomplete team.
There are no registration fees or minimum distance requirements, and part of your journey can be undertaken by public transport. Non-cyclists are not left out: one team member is allowed to commute on foot, by skateboard or by any other means of non-motorised transport.
This year, CERN’s participation in the Bike to Work challenge takes on a new dimension. We will be participating alongside the Canton of Geneva and more than 40 other local entities, including municipalities, autonomous public establishments and other international organisations in Geneva.
This means several tens of thousands of us will be coming to work by bike, which will send a strong and positive message in favour of active mobility, physical activity and good health in Geneva. The “big winners” will be rewarded with a special prize offered by the Canton of Geneva.
You can find more detailed information about the general event and our very own “Bike to CERN” initiative, which runs all year round, on the Bike to Work and Bike to CERN webpages.
Safety first: don’t forget to check out the Safety rules for cycling and the Road safety pages and to complete the online course Road Traffic – Bike Riding before getting in the saddle.

While further work is to be done, no technical showstoppers have been found. From the perspective of the technical schedule alone, operations of the Higgs, electroweak and top factory FCC-ee could start in the early 2040s.
In China, a technical design report for the Circular Electron–Positron Collider demonstrates significant progress towards a facility that could operate in the second half of the 2030s, along with excellent prospects for approval and funding (p39). Meanwhile in the US, there is renewed interest in colliding muons, for which major technology challenges remain (p45).
All proposed future colliders have a rich physics case rooted in deeper investigation of the Higgs sector, and Europe needs to move fast to minimise the gap between the LHC and the next collider at CERN (p43). If the feasibility study shows that the FCC can be afforded, then it represents the best available option for the future of CERN and particle physics.
