George Kalmus (1935–2026)
George Kalmus (1935–2026) — It is with great sadness that we learned that George Kalmus passed away on 27 May at the age of 91. George had a long and distinguished career in experimental particle physics, not only at CERN, where he played a leading role in many experiments, but also at the Rutherford Appleton

Accelerator Report: Excellent performance at the LHC
The LHC has successfully reached the nominal performance required for Run 3, marking an important milestone in the 2026 physics programme. It has now entered a special run with a reduced number of collisions per bunch crossing

Accelerator Report: We reached 100!
On 6 October, the total integrated luminosity passed the symbolic mark of 100 fb⁻¹, exceeding the forecast curve. This allowed the bunch intensity to be increased to explore the intensity reach and limitations in view of the HL-LHC era

Accelerator Report: Good performance for some, swift recovery for others
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

Particles are back in the accelerators
The four accelerators that feed into the Large Hadron Collider have all been restarted, while the LHC itself will receive its first particles in April

Accelerator Report: Recommissioning on track as the first beams progress through the complex
The recommissioning of the accelerators is progressing according to schedule. Unsurprisingly, some issues have arisen, but they have been swiftly addressed by equipment experts. First physics in the PS East Area and n_TOF is scheduled to start next week

Accelerator Report: Preparing the LHC and its injector complex for the 2024 lead-ion run
The physics run for the SPS North Area will start on 4 November, followed by the LHC lead-ion physics run on 6 November, and the PS East Area on 11 November

Bringing black hole jets down to Earth
The Fireball collaboration has used CERN’s HiRadMat facility to produce an analogue of the jets of matter and antimatter that stream out of some black holes and neutron stars

Accelerator Report: Exploring potential performance increases
The LHC injector chain has been switched to a new beam production scheme to explore its potential to produce more collisions in the LHC and to compare its performance to that of the standard LHC beam

Accelerator Report: Already a fifth of the way there
The LHC is performing well and the injector complex is treating its experimental users to a high level of beam availability
