After two years of planning, one year of implementation, and two million CHF worth of investments, the Tracker project has achieved its most important goal to enable the “Tracker Going Cold”.
Building robots, using 3D printers and testing chemical reactions is an excellent way to spend your Saturday.
CMS has many different safety systems installed in the underground experimental area. These are designed to protect the detector and all the associated electronics as well as the cavern itself. In case of fire, the last line of defence is the High Expansion Foam System.

The first part of the CMS endcap calorimetry, as seen by particles coming from interactions in the centre of the detector, is the "ECAL Preshower" or "ES" for short.
Former Deputy Spokesperson became head of the CMS experiment this month as Joe Incandela’s term came to a close.
Building and operating the CMS Detector is a complicated endeavour! Now, more than 20 years after the detector was conceived, the CMS Bologna group proposes to follow the steps of this challenging project by playing "The Higgs Boson Goose Chase" game, illustrating CMS activities and goals.
The central hadron calorimeter (HCAL) of CMS consists of the barrel (HB), the endcap (HE), and the outer (HO) regions. The HO consists of one or two scintillator layers and uses the metal of the magnet system as an absorber.
A fourth station –– called RE4 –– will be added to the CMS endcap muon system during the ongoing LHC Long Shutdown (LS1).
