Preparing for the first beam "splashes"

After a two-year hiatus, proton beams will soon start to circulate in the LHC and, in a couple of months from now, we will have the first collisions at 13 TeV, nearly twice as much as in the first run of the LHC back in 2010-2012. Many things have improved in the LHC, to allow this higher energy, but many things have also happened in the CMS detector too. Some changes and repairs of hardware have been made, along with many improvements to "firmware" - the computer programs embedded in the custom-made electronics that control the detector - and software.

The CMS detector is now wheelchair accessible

One of 2014’s important milestones at the CMS experimental site was the successful installation of a lift for providing wheelchair access to the deep-underground detector cavern.

The CMS experimental site, located in the French commune of Cessy, hosts one of CERN’s major scientific instruments and is a popular visit point.

“We estimate around 50,000 visitors will have been to the CMS experimental cavern during the current shutdown (December 2012 – March 2015),” says Austin Ball, CMS Technical Coordinator.

CMS open for Virtual Visits, from your school, science festival or exhibition centre

“Welcome to the CMS Experiment. We are 100 metres underground and I will now pass by the eye scanner to take you for a virtual tour and show you our massive scientific machine,” said CMS physicist, Abdollah Mohammadi, to 200 enthralled students sitting in the hall in the Sharif University of Technology in Iran last Tuesday.

LHC data brought to life through music

Guest post by Chiara Mariotti


I first studied music at the Conservatorio di Torino when I was in high school but stopped during my university studies. I returned to music maybe 25 years later, when my kids started to play instruments (they play the trumpet and the saxophone). I felt great joy when I resumed playing and I discovered that I was still able to; my fingers were playing even without my conscious control of them. I soon joined the Thoiry harmony group (L'Echo du Reculet) and then enrolled at the local municipal school to take flute lessons again.
