CERN’s Swiss post office is moving

Mon, 13/09/2021 - 18:49
CERN’s Swiss post office is moving thortala Mon, 09/13/2021 - 17:49

As of Friday, 1 October 2021, the post office located in Building 500 on the Meyrin site will move to the Kiosk operated by Novae, opposite the current branch, which will close permanently. The new office will take the form of a partner branch in the Kiosk, a system that eliminates certain constraints while maintaining an equivalent level of postal services and allowing customers to simultaneously access services provided by the Kiosk.

The vast majority of postal services will still be offered at the new postal branch at the Kiosk, including sending letters and parcels abroad, buying stamps and making withdrawals with the PostFinance card or payments with any debit card. In addition, the convenient opening hours will facilitate your operations – the branch will be open from 8 a.m. to 4 p.m. from Monday to Friday, just like the Kiosk.

This organisational change was prompted by a continuing decline in business volume due to a shift in consumer habits towards digital transactions. The new model of partnered branches, which exists at more than 1200 locations throughout Switzerland, will be better suited to these new practices. The staff of the current post office will be relocated to another post office in the region.

The current CERN postal branch will remain open until Wednesday, 29 September 2021.

When: 6 September 16:30
Speaker: Maurizio Conti, PET Physics and Reconstruction, Siemens Healthineers
Where: The seminar will take place on Zoom
For more information, please visit:

A brief historical review of time-of-flight (TOF) positron emission tomography (PET) will be presented, including the recent developments in silicon photomultipliers (SiPM), which have resulted in improved TOF performance. The principles of TOF PET physics and a discussion of the technical and clinical advantages of TOF PET compared to conventional PET will be presented, including the concept of time resolution and its effect on TOF gain in signal-to-noise ratio (SNR), as well as properties such as reconstruction robustness to inconsistent data, convergence, and convergence speed. Other advanced reconstruction methods and innovations will be discussed, such as resolution recovery methods, data-driven methods for motion correction and the recent introduction of deep learning in various aspects of PET.

From the hardware point of view, we will review the most recent and exciting developments towards long axial field-of-view – or total-body – PET/CT scanners: design trade-off, characteristics and performance, challenges and advantages, including new applications enabled by very high-performance TOF PET scanners in the field of low-count imaging, theranostics and monoclonal antibody imaging, and dynamic and parametric imaging with simultaneous coverage of multiple organs.

Finally, we will briefly comment on the near future of PET and TOF PET in terms of possible technology developments and the need for fundamental research to push the field forward.

Online “lightning talks” from the 2021 CERN openlab summer students CERN openlab anschaef Thu, 08/26/2021 - 11:02

On Monday, 6 and Tuesday, 7 September, the 2021 CERN openlab summer students will present their work at dedicated public “lighting talk” sessions (session 1, session 2).

In five-minute presentations, each student will introduce the audience to their project, explain the technical challenges they have faced and describe the results of their investigations. It will be a great opportunity for the students to showcase the progress they have made so far and for members of the audience to be informed about these cutting-edge IT projects, the solutions that the students have come up with, and the potential future challenges they have identified.

Due to the pandemic, this year’s CERN openlab Summer Student programme is taking place online, with the selected students participating remotely from their homes across the globe. Over nine weeks (June–August 2021), the CERN openlab summer students have been working – via remote connection – with some of the latest hardware and software technologies, as well as learning about how advanced IT solutions are used in high-energy physics. This year, 28 students from 16 different countries were selected for the programme. They have also participated in a series of lectures given by IT experts on advanced CERN-related topics.

Join us on 6 and 7 September to discover the exciting work the students have carried out, bringing innovative ideas and fresh perspectives to the IT challenges faced at CERN. The presentations are free and open to all. On both days, the sessions will begin at 4.00 p.m. CEST and will last under two hours. Follow the live webcasts via the links below:

Changes in the Swisscom mobile coverage on the CERN Meyrin site thortala Wed, 08/11/2021 - 11:27

Following the re-allocation of mobile telephony frequencies in France, the Swisscom site providing 3G coverage for the western part of the CERN Meyrin site (from the water tower to Gate E) will be switched off permanently by the telecommunications operator on 21 August 2021. A replacement Swisscom 4G service will be made available by the telecommunications operator as soon as possible.

Consequences (until the new Swisscom 4G service is established): 

  • Only Orange (French) mobile telephony coverage will be available in this area as of 21 August 2021.
  • People with restricted CERN mobile phone subscriptions cannot connect to Orange and will hence not be able to use mobile data services in this area as of 21 August.


Please note that 3G networks are being gradually phased out by telecommunications operators and 3G services will be entirely discontinued in the medium term. Consequently, 3G-only mobile phones can no longer ensure good connectivity. The mobile phones available in the CERN store are all 4G-capable.

CERN Alumni are invited to come together on 1-3 October for the second major reunion since CERN’s alumni programme launched in 2017. The event will take place online, enabling alumni from across the globe to participate. Today, CERN’s alumni network – also open to those currently working at CERN – includes more than 7000 people located in over 100 countries.

The event has the title “CERN Alumni Second Collisions: Research Matters”. It will be run using an online platform that facilitates serendipitous interaction between participants, as well as providing a broad choice of activities. Participants will be able to go on virtual tours of CERN’s infrastructure, play fun games and access exclusive talks – both from leading figures at CERN and from alumni with fascinating stories to tell. Alumni speakers will include Shannon Towey of NASA’s Jet Propulsion Laboratory; Michael Feindt, founder of the software and consultancy company Blue Yonder; Kitty Liao, founder and CEO of Ideabatic, which has designed an innovative system for transporting vaccines; and Grzegorz Wrochna, president of the Polish Space Agency. Participants will also be treated to a special talk by Oliver James, the chief scientist at Double Negative (DNEG), one of the world's leading studios for visual effects and animation. He will speak about the fascinating process undertaken by DNEG, in collaboration with Nobel-Prize-winning physicist Kip Thorne, to create the special effects for the film Interstellar, earning them an Oscar for best visual effects.

The event will be a celebration of you, the diverse range of people who have made – and continue to make – CERN the unique place it is. We also want to recognise the impact that CERN Alumni have on the wider world, adapting skills, knowledge and values developed at the Laboratory to tackle a broad range of challenges faced by society. For the first time ever, special prizes will be awarded to alumni who have made a major positive impact on the development of this vibrant community.

Just because the event is taking place online, this does not mean you have to attend alone. Alumni are encouraged to come together in their regional groups – with full respect for the local COVID-19 restrictions in place at the time – to connect to the event. There will be prizes and challenges as well as special packages – filled with CERN- and Geneva-themed goodies – sent out by the CERN Alumni team.

“Whether you’re a member of CERN’s Alumni community or you’re working at CERN today, join us for a weekend like no other,” says Rachel Bray, Head of the CERN Alumni programme. “Wherever you are in the world, whatever your background, we have talks and activities guaranteed to both inspire and entertain you, as well as opportunities to reconnect and develop your network.”

CERN has committed to a general policy geared towards protecting the environment and developing technologies to minimise the Laboratory’s impact on the climate and the local area.

In this framework, the Mobility Centre has launched a pilot scheme for the deployment of electric scooters and bicycles. The scheme will be operated in partnership with Urban Connect, which will provide the mobile app. To find out more, consult the terms and conditions or go to the Bike Sharing website.

The 10 scooters and 30 bicycles, which supplement the traditional bicycles already available, can be easily reserved using the Urban Connect app and can be picked up on the Meyrin and Prévessin sites. They are available free of charge for use on the CERN sites and between stations during CERN’s opening hours.

They may not be taken outside CERN, and any user going beyond the authorised perimeter will receive a notification. Each scooter and bike is equipped with IoT technology that allows it to be located and a maintenance record to be kept.

Charging stations are available at each collection point to ensure that the whole fleet is continuously operational. The necessary safety and security accessories, including helmets, antitheft devices and fluorescent jackets, are also provided.

We encourage as many of you as possible to make use of this pilot scheme and enjoy the benefits of environmentally friendly transport.

Blood donation: urgent appeal to blood donors Medical Service anschaef Tue, 07/20/2021 - 11:08

The summer has arrived, and the blood donation campaign in France and Switzerland has started. Until the context allows us again to organise a campaign here at CERN, we would like to inform you of the different places where you can donate blood alternatively.

In June, the numbers of blood donations was lower than expected. Therefore, The HUG Blood Transfusion Centre (CTS) initiated an urgent appeal to blood donors. Dr Sophie Waldvagol, the doctor in charge of CTS, warned that “during the first six months of the year we narrowly obtained the number of donations necessary to treat HUG patients. The situation is very tense at the beginning of summer. The vast majority of collections within companies have been cancelled and, after a year of pandemic, fewer donors are in number.”

Blood donation is an act of solidarity to save lives. We encourage you, if possible, to do it.

Who can donate blood?

  • Be between 18 and 60 years old for the new donors. Up to 75 years old for regulars donors in Switzerland and up to 70 years old for regular donors in France
  • Weigh at least 50 kg
  • Be in good health and feeling well

Donate blood in Switzerland

If you have been vaccinated in Switzerland with the Pfizer/Moderna or BioNTech vaccine, you have to wait 48 hours before donating blood. If you have been vaccinated with any other vaccine, please show on your donation day your vaccine attestation with the name of the vaccine. If you had any symptoms after your vaccine, please wait 7 days after the symptoms have gone away to donate blood.

You can answer an online questionnaire to see if you can donate blood, and the available places to do so.

Here are the next available collection spots in Switzerland:

  • HUG Centre of Blood Transfusion, Monday, Tuesday, Wednesday and Friday from 7h30 until 15h / Thursday from 11h until 19h / 1st and 3rd Saturday of the month from 8h30 until 12h00.
    Make here your appointment online to donate blood
    Rue Gabrielle-Perret-Gentil 6, 1205 Genève
  • Salle des fêtes de Vernier, the 25/08 from 15h00 until 19h00
    Route de Vernier 200, 1214 Vernier

Donate blood in France

In France, you do not need to wait after your vaccination. But here are some restrictions: you cannot donate blood if you do not feel well or not in good health, if you have any symptoms of flu or loss of smell and taste in the last 2 weeks, if you had any close contact with someone infected with the coronavirus in the last 2 weeks, or if you were tested positive for the coronavirus in the last 4 weeks.

In France there is also an online questionnaire that you can answer and see where and if you are eligible to donate.

Here are the next available collection spots in France:

  • Salle du Levant, the 03/08 from 14h30 until 19h00
