This week and next see a series of meetings looking at the future of CERN, and indeed of particle physics, says Director-General Rolf Heuer
Radiofrequency cavities built for the Large Electron Positron Collider are finding use on the SESAME project
As the LHC’s first long shutdown, LS1, enters its second calendar year, it’s a good time for a mid-term report on how things are progressing
This week LS1 successfully passed an important milestone: the first pressure test of a complete sector, sector 6-7
There’s much to look forward to in 2014 – let’s make it another safe and successful year at CERN, says Director-General Rolf Heuer
Higgs boson decays, a Nobel prize for Higgs and Englert and a huge Open Days event were among the big stories at CERN this year
The excellent progress of the maintenance work on CERN's accelerators, which is overwhelmingly on schedule, was praised by the CERN Council last week
ATLAS is improving its trigger system to be able to select even more collision events with potentially interesting physics
Updates from the EuCARD, TIARA, and HiLumi projects in Issue 8 of Accelerating News. Now available online
Testing on the LHC’s replacement RF cryomodule was completed last week in SM18
The Compact Linear Collider (CLIC) study is looking at silicon capacitors to help with power pulsing
When night falls over CERN, a team of X-ray experts go underground to perform tests on the Large Hadron Collider
