The D2 prototype magnet, developed and manufactured in Italy, has been integrated and tested in the longest HL-LHC cold mass with corrector magnets from China and CERN

In about a week, lead ions will be sent from the SPS into the LHC to collide in the accelerator’s four big experiments

The LHC resumes beam production, following the repair of the inner triplet vacuum leak, and gears up for heavy ion collisions

The many CERN-developed sensors and software programs of the FRAS (Full Remote Alignment System) have been successfully tested on a prototype magnet in preparation for the HL-LHC

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
