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
The 2025 run was successfully completed on 8 December at 6.00 a.m., signalling the start of the year-end technical stop for the LHC and the injector complex
So far the summer run has seen solid progress in luminosity production, but also some unexpected beam and machine behaviour. Careful monitoring revealed a hardware issue, now being closely watched as the LHC continues to perform at full capacity.
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
Soon, CERN personnel will take a well-deserved winter break, just like the accelerator complex. Following a successful year, the remainder of the accelerator complex was stopped on 2 December, marking the official start of the year-end technical stop
The year-end technical stop (YETS) officially started on 30 October, with promising performance tests in Linac4. The injection of the first 2024 LHC beam is scheduled for 11 March 2024
The beam commissioning of the Antiproton Decelerator will start on 12 June, and the aim is to deliver antiprotons to the eagerly waiting AD-ELENA experiments on 30 June
On 7 March, beams were circulated in the SPS for the first time this year. In this article, we reflect on the successful commissioning of the accelerator’s new beam dump
