Explore the CERN accelerator complex, filmed during the exceptional #CERNOpenDays visits. Each Sunday evening, we will release a new video. Watch the final episode where physicist Freya Blekmann and Accelerator Director Frederic Bordry answer questions such as: Do Dark Matter and Dark Energy really exist? What is exactly the Standard Model and can you blow up the accelerator with your experiments? | CERN

The LHC tunnel and that of its successor, the High-Luminosity LHC, are now connected. This week, the civil engineering companies made the junction between the underground facilities at Points 1 and 5 of the accelerator. Lucio Rossi, Leader of the HL-LHC project, Frédérick Bordry, Director for Accelerators and Technology, Fabiola Gianotti, CERN Director-General, and Oliver Brüning, Deputy Leader of the HL-LHC project, met this morning in the LHC tunnel to celebrate the breakthrough.

The ATLAS Experiment at CERN has recently finalised the upgrading of one of the experiment’s sub-detectors, called the Small Muon Wheel (in spite of its 10m size, which is nothing but small!). In this teaser, announcing a live event featuring the detector, the new Small Muon Wheel is seen at the LHC surface hall, being finalised before being lowered 100 metres underground.
