Scroll through the photo diary to relive the repair of the LHC

Despite challenging working conditions, the vacuum leak caused by the quench that occurred on 17 July was repaired in less than 10 days

Plasma accelerator AWAKE has tested scalability and is all set to begin its second phase of data taking with an upgraded plasma source

On Monday, 17 July, the LHC beams were dumped after only 9 minutes in collision due to a radiofrequency interlock caused by an electrical perturbation

On Friday, 30 June, an exciting milestone was reached: the much-awaited antiproton physics season finally commenced

On Monday, 19 June, LHC operation was paused for one week to allow the technical teams to carry out preventive and corrective maintenance on the machine and its subsystems

The AD operations team received on Friday, 1 June – 12 days earlier than rescheduled – the green light from the AD injection kicker expert: beam could be injected again in the AD ring

On 11 May, four days before the original schedule had set a target of 1200 bunches per beam, the LHC made its final intensity ramp-up step to 2400 bunches per beam

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

Another important milestone was achieved in the LHC beam commissioning: on 21 April, the LHC Engineer in Charge declared “stable beams” at 6.8 TeV, the first time in 2023
