“Shape memory” material provides a solution for the HL-LHC

A collaboration between CERN and the University of Calabria is developing a new connection device for vacuum chambers based on Shape Memory Alloy (SMA) rings, for future use in the High-Luminosity LHC (HL-LHC). The unique characteristics of these materials, able to memorise different shapes at high and low temperatures, are being exploited to create a high-tech solution for sealing the vacuum chambers of the upgraded accelerator. >>

The IR Sector – Opening new horizons for CERN

Last week saw the CERN family grow by one, as we welcomed Cyprus as an Associate Member in the pre-stage to Membership. This gives me a good opportunity, three months into the job, to share the vision for the new International Relations (IR) Sector. CERN is and always has been an incredible example of successful, inclusive international collaboration and exchange in the pursuit of common goals. The IR Sector continues and builds on that tradition and spirit. >>

LHC Report: machine commissioning - looking good

Since first beam was injected on Friday, 25 March, the recommissioning of the LHC has made good progress. >>

Prototype HL-LHC magnet undergoes testing

Lighting the way: how emergency lights survive radiation

 LHC tunnel emergency lights are part of an essential safety system if you ever need to evacuate. >>

Computer Security: Mac security – nothing for old versions

A fundamental pillar of computer security is the regular maintenance of your code, operating system and application software – or, in computer lingo: patching, patching, patching. >>

Ombud’s Corner: defeating unconscious bias

Do you have a tendency to switch off at meetings every time a particular colleague starts to speak? Is it obvious to you that your colleagues will never accept a peer as a project leader? And doesn’t that candidate from your own alma mater clearly have a definite edge over the others? >>

Our dear colleague and friend, Sylvestre, has gone suddenly from our lives leaving us in great sadness and disbelief.  >>

The Globe reopens its doors

After a year of work, the newly renovated Globe of Science and Innovation will open its doors again at 10 a.m. on Tuesday, 19 April. >>
