Today’s #PhotoOfTheWeek features the first series of cryogenic lines built at CERN for the High-Luminosity LHC. The #HiLumiLHC will rely on several key innovations in accelerator technology. These stainless steel lines are designed to bring liquid helium into the crab cavity cryomodules.

📣 CERN scientists find evidence of quantum entanglement in sheep 🐑 ​​Quantum entanglement is a phenomenon where two particles’ states are tied to each other, no matter how far apart the particles are. These findings could now help to explain the species’ fascinating flocking behaviour.

Last Friday, we asked you the question.. Today, we hear the answer from Oscar, who works in the Mechanical Measurements Laboratory at CERN. #CERNMechlab There, scientists take the measurements of a wide range of components and devices for present and future high-energy physics projects.

Symmetry between up and down quarks is more broken than expected Surprising results from the NA61/SHINE collaboration #AtCERN show that this so-called isospin asymmetry could point to gaps in physicists’ understanding of how quarks and gluons combine. Find out more: home.cern/news/news/ph...

Did you know that a Telescope Project Division was based #AtCERN? Today we #ThrowbackThursday to August 1973. Here we see the control system that was to be fitted to the 1m photometric @eso.org telescope. It was believed to be the most advanced built at that time.

Making a splash: cosmogenic candidate lights up KM3NeT #ICYMI: on 13 February 2023, strings of photodetectors anchored to the seabed off the coast of Sicily detected the most energetic neutrino ever observed at an estimated energy of 220 PeV, smashing previous records. 🎥 made available by #KM3NeT

Piece by piece, the High-Luminosity Large Hadron Collider is taking shape. Its improved performance will partly be the result of the new so-called “inner triplet” magnets, which will focus the proton beams prior to collision, increasing their overlap, and thus the probability of collisions.

The High-Luminosity Large Hadron Collider (#HiLumiLHC) will rely on several key innovations in accelerator technology. One such technology is this pre-series cryomodule, which will be tested in the Super Proton Synchrotron (SPS) in the coming year.

#ThrowbackThursday to a warm day of July in 1974, when the boring of the tunnel that would house the Super Proton Synchrotron (SPS) – the second-largest machine in CERN’s accelerator complex – was completed.
