The Future of HEP Computing Considered
The Future of HEP Computing Considered We are well-used to long lead times in particle physics. Detectors that are commissioned often rely on technology that was in an R&D phase decades before and now, as the CERN community, we now plan for new accelerators that will still be operational at the end of this century.

Reducing the greenhouse gas emissions from particle detection systems at CERN: status and perspectives.
Reducing the greenhouse gas emissions from particle detection systems at CERN: status and perspectives. At CERN experiments, some particle detector systems are operated with gas mixtures containing fluorinated gases. These gases are essential for achieving the specific detector performance required for data taking (e.g., long-term stability, time resolution, rate capability). However, these fluorinated gases (tetrafluoromethane

Truly non-destructive: Antimatter under the microscope during the 2024-YETS
Truly non-destructive: Antimatter under the microscope during the 2024-YETS Early in the morning, on the 13th of November 2023, the AD/ELENA facility delivered its final antiproton bunch to the users at the antimatter factory. Most of the particles annihilated a few minutes later in antihydrogen formation and its spectroscopy, and most of the AD/ELENA users
