Open-heart surgery for CMS

3 Mar 2017

This week the CMS collaboration is replacing the heart of its detector: its tracking system. The system determines the trajectories of charged particles and it is made of two components, the Pixel Tracker and the Strip Tracker.

The Pixel Tracker is being replaced with a brand-new one: its upgrade is among the most important EYETS activities for CMS and another feather in the cap of a busy but productive period for the collaboration.

The second-generation Pixel Tracker will operate until the early stages of the High-Luminosity LHC, when it will itself be replaced with a third-generation device.

With the replacement happening throughout the week, more news to come, including our Facebook Live where our experts answer your top questions:

CERN, the European Organization for Nuclear Research, is one of the world’s largest and most respected centres for scientific research. Its business is fundamental physics, finding out what the Universe is made of and how it works. At CERN, the world’s largest and most complex scientific instruments are used to study the basic constituents of matter — the fundamental particles. By studying what happens when these particles collide, physicists learn about the laws of Nature.

The instruments used at CERN are particle accelerators and detectors. Accelerators boost beams of particles to high energies before they are made to collide with each other or with stationary targets. Detectors observe and record the results of these collisions.

Founded in 1954, the CERN Laboratory sits astride the Franco–Swiss border near Geneva. It was one of Europe’s first joint ventures and now has 22 Member States.
