Remember how #CERN banned Russian scientists after the invasion of Ukraine? I wonder if US scientists will get the same treatment.

(I have my money on US dollars being more valuable than roubles.)

Breakthrough in antimatter production

In a paper published today in Nature Communications, researchers at the ALPHA experiment at CERN’s Antimatter Factory report a new technique that allows them to produce over 15 000 antihydrogen atoms – the simplest form of atomic antimatter – in a matter of hours. “These numbers would have been considered science fiction 10 years ago,” said Jeffrey Hangst, spokesperson for the ALPHA experiment. “With larger numbers of antihydrogen atoms now more readily available, we can investigate atomic antimatter in greater detail and at a faster pace than before.” To create atomic antihydrogen (a positron orbiting an antiproton), the ALPHA collaboration must produce and trap clouds of antiprotons and positrons separately, then cool them down and merge them so that antihydrogen atoms can form. This process has been refined and steadily improved over many years. But now, using a pioneering technique to cool the positrons, the ALPHA team has increased the rate of production of antihydrogen atoms eightfold. This spectacular advance in the production rate is all down to how the positrons are prepared. First, the positrons are collected from a radioactive form of sodium and contained in what is known as a Penning trap, where fine-tuned electromagnetic fields hold the antiparticles in place. However, they do not remain still. Like a tiger in a zoo, the positrons circle their cage, causing them to lose energy. This cools the cloud of positrons, but not enough for them to efficiently merge with the antiprotons to form antihydrogen atoms. So, the ALPHA team recently tried a new approach, which was to add a cloud of laser-cooled beryllium ions to the trap so that the positrons would lose energy in a process called sympathetic cooling. This got the positron cloud down to a temperature of around -266 °C, making it much more likely to form antihydrogen atoms when mixed with the antiprotons. This approach allowed over 15 000 antihydrogen atoms to be accumulated in under seven hours. To put this into perspective, it took a previous experiment 10 weeks to accumulate the 16 000 antihydrogen atoms required to measure the spectral structure of antihydrogen with unprecedented precision. “The new technique is a real game-changer when it comes to investigating systematic uncertainties in our measurements.  We can now accumulate antihydrogen overnight and measure a spectral line the following day”, said Niels Madsen, deputy spokesperson for ALPHA and leader of the positron-cooling project. Using this approach for cooling positrons, the ALPHA experiment produced over 2 million antihydrogen atoms over the course of the experimental runs of 2023–24. And this year, the researchers are making use of the unprecedented numbers of antihydrogen atoms to study the effect of gravity on antimatter as part of the ALPHA-g experiment. This technique will allow even more precise measurements to be made and make it possible to probe deeper into the properties and behaviour of atomic antimatter.

"Vor 10 Jahren noch Science-Fiction": Antimaterieproduktion am CERN beschleunigt

Dauerte die Produktion größerer Mengen von Antiwasserstoff vor Jahren noch wochenlang, reicht inzwischen eine einzige Nacht. Das hilft der Grundlagenforschung.

@heiseonline Huuuh, cool 🫩😴😉😅

Weiß noch, wie das losging mit CERN, #Kernfusion sollte verstanden sein, verbesserte Materialien sollten ermöglicht werden, das #Energieproblem der Menschheit sollte gelöst sein. Leider ist nix davon eingetreten, oder?!

Was hat das bisher so gesamt gekostet, mindestens 10 Milliarden €?

Ich glaube ja, die größte Errungenschaft des CERN ist das #worldwideweb 😂 und das verschlingt eher Unmengen an Energie.

Today, our CEO, Adriana Groh, is at #CERN for their annual #OpenSource event, where she spoke and was on a panel with @zendis @openuk, as well as CERN and Red Cross representatives on how international organizations can proactively strengthen software they depend on.

We are glad to be able to support CERN—the birthplace of the World Wide Web—with our expertise and experience in increasing the resilience of critical open technologies.

It’s the kind of action we want to see more of: organizations like #CERN taking an active role in supporting the open source technologies they depend on.

We’re excited to also highlight that with our support, CERN is commissioning a new #SecurityAudit of @ente Auth, the open source two-factor authentication tool used across their internal IT systems. The audit will help ensure the tool remains secure, resilient, and reliable. 2/2
