Open-heart surgery for CMS

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 webcast where our experts answer your top questions:
