I'm glad to see there are more data to be found in the run 2 datasets! It will also be interesting to see what comes out of the HL-LHC project. It has already been in the making for years.

I did my 2.5 year fellowship on it in 2017 to 2019, but I'm not very familiar with the interactions they're studying here. W and Z were discovered at CERN in the early 80s though using the LEP accelerator, the LHC's predecessor.

Pioneering #CERN scheme will pay publishers more if they hit #openscience targets
#Physics funder will provide financial incentives to encourage practices such as data sharing and transparent #peerreview.
Journals publish work from field openly and at no cost to authors, in exchange for bulk payments. Under initiative, CERN will pay more to publishers that adopt polices such as public or open peer review and linking research to data sets, and less to those that don't.

The Compute Group in #CERN IT is hiring a #Kubernetes engineer! Join us and help shaping the cloud native infrastructure at CERN, the largest particle physics laboratory in the world! jobs.smartrecruiters.com/CERN/ #K8s #OpenStack

CERNKubernetes Service Engineer (IT-CD-PI-2025-18-LD)Company Description: At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature. Find out more on http://home.cern. Job Description: IntroductionInterested in supporting and helping shape the evolution of the cloud native infrastructure at CERN?

Experience:We are looking for someone with the following demonstrated experience/skills:* Demonstrated experience in developing and supporting Kubernetes platforms and services to end users with distinct use cases; * Extensive knowledge of containers and container orchestration systems, in particular Kubernetes, Prometheus, Harbor, Argo and other tools in the cloud native ecosystem; * Familiarity and previous experience with DevOps practices; * Additional experience in the following areas would be an asset; * Experience in operating and optimising large scale infrastructures; * Experience with private cloud computing platforms, such as OpenStack, or public cloud providers, such as AWS, GKE, or Microsoft Azure, would be an asset; * Previous experience collaborating with projects and communities in the Cloud Native Computing Foundation (CNCF). Technical competencies:* Knowledge of operating systems; * Knowledge of system configuration tools; * Architecture and design of ICT systems; * Identification and selection of relevant emerging ICT technologies; * Knowledge and application of software life-cycle tools and procedures. Behavioural competencies:* Working in teams: working well in groups and readily fitting into a team; participating fully and taking an active role in team activities. Cooperating constructively with others in the pursuit of team goals; balancing personal goals with team goals. * Solving problems: addressing complex problems by breaking them down into manageable components. Recognizing what is essential; discriminating between important and peripheral information and being able to see the whole picture. Testing solutions for long-term suitability, cross-checking with all concerned before implementation. * Managing self: taking initiative beyond regular tasks and making things happen. Working well autonomously; taking on activities and tasks without prompting. * Building relationships: showing appreciation for the ideas and contributions of others and encourages others to express their views, even if controversial Being able to put self in the shoes of others in order to understand their needs and interests. Language skills:Spoken and written English: ability to understand and speak the language in professional contexts.

Tim Berners-Lee created the first website info.cern.ch at CERN in 1990. It was a simple page explaining what the World Wide Web was and how to set up a web server. Along with it, he also built WorldWideWeb (renamed Nexus), the first-ever web browser, which only ran on NeXT computers. This is not to be confused with the "World Wide Web" aka: the internet, which seems to be a common mistake. Unfortunately the browser is no longer available that I have found.

The second browser? That was Line Mode Browser, released in 1992. Unlike WorldWideWeb, it could run on multiple operating systems and was the first browser many people used to access the web. You can still get the source code for Line Mode Browser, or launch the simulator line-mode.cern.ch

The internet was never the same again.

CERN ends cooperation with Russian institutes

Following the full-scale #invasion, the #CERN Council in 2022 declared its intention to terminate its International Cooperation Agreements (ICAs) with #Russia and #Belarus after their expiration in 2024. The Council affirmed the decision in fall of 2023

Here are a few pictures of a work project I have been developing and assembling in the past weeks.
It's a SiPM (SiliconPhotoMultiplier) with a pre-amplifier intended for detecting really small amounts of light.
It will get used at #CERN for quality control of GEM detectors.

The SiPM was placed with a 'Fine-Placer' that has a nice camera system to easily align the part to the PCB.

Closeup of the SiPM assembly process. A 6x6 grid of solder paste has been printed on the PCB. The paste amount on each pad is not exactly the same. Above the board, the SiPM is hovering on a vaccum pickup.
Two overlaid pictures. In red, the bottom of the SiPM In the background, the PCB where the SiPM needs to be placed. They are not aligned yet.
Fully assembled board. SiPM on the left. The size of the PCB is 9x35mm. That is rather small.
Backside of the same PCB. * a JST-PH connector for power * a trim-pot to set the bias voltage with a red calibration dot * two keystone SMT test points below the pot * a single mounting hole * a MCX connector for the output signal

Mysteries of the universe revealed? Hardly. But CERN still fascinates, discovers on its 70th anniversary.

From @AssociatedPress: "Over the last seven decades, CERN, the sprawling research center on the Swiss-French border at Geneva, has become a household name in Europe, the West and beyond, but its complex inner workings remain a puzzle to many people. Here’s a look at CERN and how its discoveries have changed the world and our view of the universe — and could change them more in coming years."
