Following the achievement of 2460-bunch stable beams on 24 May, the accelerator complex experienced an SPS magnet failure, a central timing glitch and a complex-wide power disruption. Yet the LHC remains on track to achieve its 2025 luminosity goal

On 19 May, the LHC reached 1200 bunches per beam, a level that is considered meaningful for physics. The full intensity of 2460 bunches per beam could be achieved before the end of the week

“Stable" particle beams are back in the LHC machine, marking the start of the 2025 physics data-taking campaign

The LHC operations team and many other experts have been working hard to set up and validate the accelerator for safe beam operation, leading to the first stable beams for physics of 2025 on 5 May

The LHC has restarted and both beams have been circulating in the machine since 8 April, meaning that the start of the LHC beam commissioning during Easter is apparently not a constant of nature

The first beam-based physics of 2025 has started and more will follow soon. However, some unexpected challenges will cause a small delay in the restart of the LHC

Near-miss collisions at the Large Hadron Collider are shedding light on the dynamics of gluons, which contribute 99% to the mass of protons and neutrons

The Chamonix Workshop is in full swing, and the initial outlines of the 2025 LHC configuration and operational scenarios are beginning to take shape

Although the much-appreciated winter break is well behind us and most of us are back at work, the accelerator complex is still in hibernation – but not for much longer
