As we prepare to implement the High-Luminosity LHC and secure approval of a flagship collider to follow it, we must work together to create the best possible environment for success

This technical stop is particularly intense, being both shorter than usual, to maximise the limited time for physics, and very busy, to make essential preparations for LS3, which begins in June

A look back at a year of advances in science, technology and benefits to society

The first large refrigerators for the High-Luminosity LHC have been installed

The extraordinary performance reflects decades of accumulated expertise, a culture of continuous development and improvement, and a sustained collective effort across all technical and operational domains

The software managing CERN’s compute workload has handled a massive stress test, far beyond normal operating conditions, designed to simulate the needs of the future

The accelerators that feed into the Large Hadron Collider are ready to supply more intense beams

Oliver Brüning, who has led the HL-LHC project since 2020, is handing the position of HL-LHC project leader over to Markus Zerlauth

The delivery of two huge compressors kicks off the installation of the new helium refrigerators for the High-Luminosity LHC

The LHC pre-injectors delivered excellent availability throughout recent weeks, while an SPS electrical fault and an LHC collimator vacuum leak have been overcome, allowing a successful return to full luminosity production

Following the successful oxygen and neon ion runs, protons are back in the LHC, delivering luminosity at a high rate and slowly catching up with the forecast production rate. In addition, a slight increase of the bunch intensity is being considered

The teams are making the final interconnections in the chain of magnets that will be used to test the components of the LHC's successor
