CERN engineer to go to space on Tuesday – don’t miss the launch!

Selected in 2022 from over 22 500 applicants to be one of the 11 members of the European Space Agency (ESA) 2022 astronaut class in the reserve pool, Sławosz Uznański, former CERN engineer, will go to space next Tuesday.

Sławosz and his colleagues from the Axiom Mission 4 (Ax-4) crew will take off on 10 June 2025 at 2:22 pm CEST* from NASA’s Kennedy Space Center in Florida aboard a SpaceX Dragon spacecraft. Dragon and the crew will dock the day after with the International Space Station (ISS), where they'll be spending up to 14 days.

Watch the live webcast of the launch here (from 12:15 am CEST): axiom.space/live. We also plan to show the live broadcast on the screens installed in CERN's restaurants and cafés.

More information on the Ax-4 live events here: https://www.axiomspace.com/mission-blog/ax4-mission-coverage

Settle in, reach out: a new space for CERN spouses and partners to connect

Settle in, reach out: a new space for CERN spouses and partners to connect

Have you recently arrived in the area and are looking for ways to help your spouse or partner settle in, find work or connect with others? You’re not alone – and now there’s a dedicated space to help you and your family navigate life around CERN.

To support the transition for new arrivals and strengthen community ties, HR has teamed up with the Diversity and Inclusion Officer (DIO) for the Theoretical Physics (TH) department to launch the CERN Spouses & Partners Forum.

Created by the community, for the community, this forum is designed to foster connections and the exchange of experiences, tips and advice on topics related to integrating, job hunting and more.

The forum includes several categories:

  • General discussions
  • Job search advice and opportunities
  • Information for those preparing to join CERN
  • Meet-up and networking opportunities
  • Schools and childcare resources

You are warmly invited to take part: post information, reply to questions or simply explore the discussions already going on. The more the community participates, the richer and more useful the forum will become!

As the forum is community-driven, the advice and information shared there reflect personal experiences rather than official CERN positions. For any formal guidance, please reach out directly to the relevant CERN administrative services.

On the road to rapid growth, the forum already has over 500 members – and the number keeps rising. We hope this new space will become a valuable and welcoming resource for new CERN personnel and their loved ones.

You can also find this forum and other useful resources to support spouses and partners on the Social Affairs Service website: https://hr.web.cern.ch/spousepartner-job-search-and-integration.

The May/June 2025 issue of the CERN Courier is out

Thu, 22/05/2025 - 10:45
The May/June 2025 issue of the CERN Courier is out (Image: CERN Courier)

Should a Higgs factory be a linear or circular electron–positron collider? Intriguingly, the key strategic technology may be the same in either case. Klystrons consume the majority of power at electron–positron colliders of all mature designs. The trouble is that they are typically only 60% efficient. In our cover feature, Igor Syratchev and Nuria Catalan Lasheras describe CERN’s pursuit of 90% efficiency – a feat that would have major implications for the environmental sustainability and cost effectiveness of any Higgs factory.

Klystrons date back to the development of radar in the run-up to World War II. Remarkably, astroparticle physicists are now trying to use radar to detect not enemy aircraft but ultra-high-energy neutrinos. The technology is different, but the underlying principle is the same.

This is just one facet of the ambitious global strategy described by Lu Lu of the University of Wisconsin–Madison in her feature on future neutrino observatories. Only one ultra-high-energy neutrino has been observed so far. Lu describes plans for a worldwide network of observatories offering full-sky coverage. The reward will be cosmic messengers that slice through dust and magnetic fields to point to the most extreme environments in the universe – and energies that are inconceivable in terrestrial colliders.

Elsewhere in these pages: CERN’s Verena Kain explains why AI-based automation is the future of accelerator operation; Beate Heinemann describes her strategy for DESY’s future; LHC researchers debate an unexpected pseudoscalar excess at the top–antitop threshold; DESI suggests dark energy may be evolving; an analysis of community inputs to the European Strategy for Particle Physics; how to get a job in machine learning; and much more.

Ready for heatwaves

Tue, 20/05/2025 - 13:15
Ready for heatwaves


As spring gives way to summer, we must stay prepared for whatever the season brings – especially when it comes to periods of intense heat. MeteoSwiss declares a heatwave when average temperatures exceed 25 °C for at least three consecutive days.

To help protect personnel during such events, CERN introduced its dedicated Heatwave Action Plan in 2023. This plan is only activated when an official heatwave is declared by MeteoSwiss, whose forecasts are closely monitored by the HSE unit. It sets out a range of preventive and corrective measures aimed at reducing the risks associated with prolonged high temperatures. Some of these measures may be adapted according to the operational needs of individual services.

When a heatwave is forecast, the activation and deactivation of the Heatwave Action Plan will be communicated via:

  • the home.cern and hse.cern websites
  • the CERN campus app
  • posters and messages displayed on restaurant and entrance screens.

Full details of the Heatwave Action Plan are available on the dedicated webpage.

In addition, the Beat the heat” tips offer helpful advice on staying comfortable and safe in hot conditions – both during heatwaves and in everyday warm weather.

At CERN, safety is always a priority – whatever the season.

Early-career researcher input for the European Strategy for Particle Physics

Tue, 20/05/2025 - 11:34
Early-career researcher input for the European Strategy for Particle Physics

Thanks to the involvement of many early-career researchers (ECRs) over the past few months, the organisers of the ECR white paper for the European Strategy for Particle Physics update (ESPPU) were able to coordinate a collective effort that resulted in the ECR input for the Strategy update – formulated as 55 actionable recommendations to improve our future and the future of the field.

These recommendations cover such key topics as career development, well-being, recognition, science communication and the future of both collider and non-collider projects. In parallel, the organisers released a 100-page ECR white paper (arXiv:2503.19862) detailing the arguments behind those recommendations, grounded in a community-wide survey of over 800 ECRs across Europe.

Don’t miss the hybrid event on Tuesday, 27 May (1.00–4.00 p.m. CEST) to explore and discuss these recommendations and to reflect together on how to move forward as a community. The event is open to all, regardless of career stage or affiliation. We warmly welcome your participation and input.

Geneva: Traffic disruptions due to roadworks on Avenue Appia and Nations Tunnel (Image: SIG)

Work related to the GeniLac thermal network will be carried out around the Appia intersection over the coming months by Geneva Industrial Services (SIG).

Traffic will continue to flow, but some lanes, cycle paths and pedestrian crossings will be temporarily closed, affecting all road users. It should be noted, however, that the main changes to the intersection will only come into effect after a preparatory phase scheduled to last until 3 June. 

Please find here information for residents and a notice of roadworks, including a detailed map of the area and the diversion in place.

The Swiss Mission would like to thank road users in advance for complying with the signs in place to keep traffic flowing as smoothly as possible.

Due to the CERN Relay Race, organised by the Running club and the Staff Association and taking place on Wednesday 14 May, traffic arrangements will be in place on Meyrin site from 12:00 onwards.

For everyone's safety during the race, which will last until 2:00 p.m., drivers and cyclists must give way to runners and carefully follow the instructions of guards and race organisers.

As the Staff Association is inviting all staff members and their families, as well as retired staff, to take part in its 70th anniversary celebrations on the esplanade of Restaurant 1 just after the race, Route Bell and Entrance A will be closed to vehicles until later in the afternoon.

The Security service therefore asks everyone to be extremely vigilant during these events.

Keep up to date with live traffic information and find the best itinerary on CERN Campus App or on the dedicated CERN map.

Arrêt du chauffage central le 28 avril

Fri, 25/04/2025 - 13:02
Central heating to be turned off on 28 April

The central heating will be gradually switched off throughout CERN from Monday 28 April. This date is determined mainly by the weather and night-time temperatures, in order to rationalize our energy consumption.

The environmental and financial impact of heating is substantial. Reducing the number of days of heating on campus was one of the measures included in CERN’s Energy Savings campaign launched in 2022 and part of the ISO 50001 measures.

However, the operating schedule is not the only lever for SCE department to reduce energy consumption linked to infrastructure heating. In addition to modernising facilities, a detailed inventory of equipment is being conducted to optimise power and automation systems and adjust settings as precisely as possible.

We thank you for your understanding and efforts.

Find out who won the Spring Biodiversity Scavenger Hunt

Thank you to everyone who participated in the Spring Biodiversity Scavenger Hunt!

We hope you enjoyed exploring the site’s biodiversity. Maybe it even inspired you to take your own nature walks on the site, too.

Congratulations to Felix Schlepper (EP-AIP), who answered each question correctly and was selected in the prize draw. The CAGI Choco Pass will allow him and a plus one to spend a day sampling chocolate from shops all over Geneva.

Many thanks to the Site and Civil Engineering department, who developed the biodiversity walk website, and the CAGI Cultural Kiosk at CERN and Geneva Tourism who provided the prize.

You can find the solutions below.

Solutions

  1. Eighteen species of which type of plant can be found across the CERN sites?
    A: Orchid. 18 different species were observed during the inventory conducted in the spring of 2022.
  2. Which snake can be seen slithering near LHC Point 6? No need to worry, it is harmless and, if threatened, will play dead.
    A: Grass snake. Recognisable by its light collar located on the back of its head, the grass snake is a harmless snake that is often found near bodies of water.
  3. Which species has yellow translucent wings and can be found near Crozet? It is not a dragonfly, even if it may look like one.
    A: Sulphur Owlfly. The Sulphur Owlfly is typically found in meadows and grassy areas where it preys on small insects, thus playing a crucial role in controlling arthropod populations.
  4. Which bird, found on the Prévessin site, has the impressive multitasking skills of eating, sleeping and even mating in mid-flight?
    A: Common Swift/Black Swift. Observed at the Prévessin site, black swifts are known to spend most of their lives in flight.
  5. Which common bird sings alongside a beautiful experiment?

Special opening hours in restaurants and cafeterias during CERN holidays

Spring is often an opportunity to enjoy a long weekend. CERN has several official holidays in April and May, during which campus services may adjust their opening hours.

During the Easter weekend, the CERN restaurants and cafeterias will be closed. From 18 to 21 April 2025, only Building 40 will offer a catering service from 08:00 to 21:00.

On 1 May, all catering services will be closed, but the many vending machines will remain available if needed.

During the Ascension holidays, Restaurant 1 (Meyrin) will be open all week, including Thursday 29 and Friday 30 May. Òdélices (Prévessin) will only be closed on Ascension Day (29/05), while all other restaurants and cafeterias will be closed throughout the long weekend.

Please check the Campus App for updated opening times and detailed maps of the catering facilities.

Register now for the 2025 CERN Relay Race!

 

The CERN Relay Race, organised by the Running club and the Staff Association, will be back on Wednesday, 14 May for its 53rd edition.

The main race will start at 12.15 p.m. in front of Building 40, closely followed by the walkers’ race and the children’s race, which is being organised with the support of the Jardin des Particules.

Like last year, the CERN Alumni Network will be taking part in the event thanks to an 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 to compete in the costume contest.

Special information: this year, the relay race will be followed by the celebration of the 70th anniversary of the Staff Association. Festivities will continue in front of R1 in the afternoon.

Registration opens on 14  April  on the CERN Running club webpage (you can also scan the QR code on the poster).

Let’s beat last year’s record participation: 156 teams and over 1000 runners and walkers in total!

Password no longer needed to sign EDH documents from May 2025

Mon, 07/04/2025 - 16:36
Password no longer needed to sign EDH documents from May 2025

The electronic document signature for EDH documents will change in May 2025. Members of the personnel will no longer need to remember and type their EDH password. Instead, they will be asked to enter their CERN computer account username to show their intent to sign the document.

If the entered username matches the one that the person used to log in to SSO, then the document will be considered signed by that person.

An information notice will be displayed on the sign screen to remind you of this change.

The change will reduce the number of support requests relating to EDH password resets and simplify the signing process for end users.

Disruption of the Storage, Recuperation and Sales service (B133)


As a precautionary measure, access to Building 133 has been temporarily suspended following diagnostics in preparation for future refurbishment work. This closure involves a temporary reorganisation of the activities normally carried out on site. A move is currently underway, and the new area is expected to be operational during the week of 21 April.

Unfortunately, this new location will not allow the full range of activities to be maintained.

The new area will not be able to accommodate suitable storage or visitors. Only the collection of materials, batteries, lighting, electronics and IT equipment, and the sale to enterprises will be able to continue for the moment.

Storage, internal reuse (including furniture) and sales to individuals have been temporarily suspended. An online solution is being considered for IT equipment.

If you have any questions or specific requests, please use the dedicated contact form.

Thank you for your understanding.

The Storage, Recuperation and Sales service
