Geneva, 16 April, 2018. A groundbreaking ceremony on 15 June 2018 will officially mark the beginning of the work to upgrade the Large Hadron Collider (LHC) to the High-Luminosity LHC (HL-LHC). This milestone project for CERN will improve the LHC’s performance to bring out its full potential. As the number of places for media representatives at this event is limited, we recommend that you save the date and send us your pre-accreditation if you plan to attend. More details about the programme will be made available at a later date.


High Luminosity-LHC kick-off event:

Date: Friday, 15 June 2018

Time: 10.00 a.m. to 2.00 p.m.

Locations: Globe of Science and Innovation, worksites at LHC Points 1 and 5

Programme: Press conference from 10.00 a.m. to 11.00 a.m., followed by the ceremony which will last until 2.00 p.m. More details to come.


The HL-LHC project is an international endeavour that began in November 2011 and was announced as the top priority of the 2013 update of the European Strategy for Particle Physics. Since the approval of the design report in 2015, prototypes have been tested at CERN, and the time is now ripe to start racing towards new physics.

The upgraded machine will deliver a higher number of proton-proton collisions per second, thanks to the increased luminosity. More collisions means more chances for physicists to investigate rare phenomena and collect more accurate measurements. 

If you are interested in attending this event, please send your pre-accreditation to by Wednesday, 25 April.
