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

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

SM18 is one of the largest magnet test facilities in the world. Dedicated to testing superconducting magnets and radiofrequency cavities, it is now waiting for the first HL-LHC components

The SPS accelerated its first LHC-type beam in May and is now sending beams to the North Area, where the physics season has started

The experiment successfully accelerated electrons with plasma wakefields generated by protons, a world first

The use of superconducting material has enabled the development of more powerful accelerating cavities

The first new PI-Mode Structure (PIMS) cavity for Linac 4 is under assembly at CERN

The switch - a test for a longer proton-lead run scheduled for January to February 2013 - presented numerous technical challenges

Linear accelerator 4 will deliver particles to the Proton-Synchrotron Booster at more than triple the energy the current linac achieves
