The crystals used in CMS’s electromagnetic calorimeter may look like simple bricks of glass, but they are in fact mostly metal and are heavier than steel! Lead tungstate crystal with a touch of oxygen in this crystalline form is highly transparent and scintillates when electrons and photons pass through it. This means it produces light in proportion to the particle’s energy. CMS contains nearly 80’000 such crystals, each of which took two days to grow. This technology developed at CERN has applications in medical imaging, for example improving cancer diagnosis. The Compact Muon Solenoid (CMS) is a general-purpose detector at the Large Hadron Collider (LHC).

120 tonnes of liquid helium in use at the Large Hadron Collider, cooling 36'000 tonnes of superconducting magnets to just 1.9 degrees above absolute zero. The cryogenic valves were designed for the needs of CERN to develop valves for use with the very low temperature of liquid helium.

The CERN computer centre has hundreds of racks like these. They are over a million times more powerful than our first computer in the 1960's. This tray is a 'dual-core' server. This means it effectively has two CPUs in it (eg. two of your home computers minimised to fit into a single box). Also note the copper cooling fins, to help dissipate the heat.

The items of this collection were created for and from the sessions of the Council and Committee of Council. The usual documents are lists of participants, agenda, minutes, progress reports and drafts of all these documents. The collection also contains a large selection of reports concerning CERN's policy in scientific, technical and administrative matters.
