Tag: luminosity
Luminosity is an important indicator of the performance of an accelerator: it is proportional to the number of collisions that occur in a given amount of time. The higher the luminosity, the more data the experiments can gather to allow them to observe rare processes.

Accelerator Report: Focus on 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

Accelerator Report: The LHC wraps up its first 2025 physics block
The proton physics run has now been paused for the first block of machine development studies, a technical stop and short oxygen- and neon-ion physics runs. Protons will be back in the machines on 12 July

Accelerator Report: LHC on track despite disruptions throughout the accelerator complex
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
