This detector is part of the ALICE experiment's Time Projection Chamber (TPC). With incredible precision, the TPC records the thousands of tracks of charged particles spraying out from the collision, allowing each particle to be identified. In such a dense, electronics-filled environment, it is rare to find a relatively empty space - yet most of the TPC's 88m3 volume is filled with just gas, with read-out detectors, like this one located on the outer surface.

A half shell of the barrel CMS Pixel Phase-0 that was installed at the start-up of the Large Hadron Collider (2009-2016 in operation) and has been involved in the discovery of the Higgs boson.

The Gas Electron Multiplier (GEM) is a state-of-the-art particle detection technology utilized in the CMS experiment at CERN. It enhances the accuracy and resolution of muon measurements, playing a pivotal role in advancing our understanding of fundamental particle physics.
