Having previously recorded that the LHC re-started on Crystal Day, April 5, 2012 after the winter shut-down, I now find that it also restarted on the same date in 2015 after having been shut down for 2 years for the … Continue reading →
ATLAS (A Toroidal LHC Apparatus) is one of four detectors receiving high-energy particles from the LHC at CERN. The detector is shaped like a barrel lying on its side in a cavern about 100 metres below the ground near the … Continue reading →
The LHC is currently the world’s largest and most powerful particle accelerator. It is the main accelerator at CERN, and consists of an underground tunnel 27-kilometres long (shown here in yellow) containing superconducting magnets, cooling systems and other infrastructure surrounding … Continue reading →
CERN (the European Organisation for Nuclear Research) is an international collaboration of scientists and engineers seeking to understand the fundamental nature of matter by using the world’s largest accelerator (the Large Hadron Collider or LHC) to create beams of high-energy particles travelling … Continue reading →
The “Review of the Safety of LHC Collisions” by the LHC Safety Assessment Group, 2008, (see references below) studied the possible production at the LHC of hypothetical objects such as vacuum bubbles, magnetic monopoles, microscopic black holes and strangelets, and … Continue reading →
