The Large Hadron Collider (LHC) accelerates and collides protons and heavy lead ions. Some may expect the Large Hadron Collider to need a large source of particles, but the proton beams used in the 27 km ring come from a single bottle of hydrogen gas that is replaced twice a year.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Particle_detector\"><\/span><span style=\"font-size: 14pt; font-family: tahoma, arial, helvetica, sans-serif;\">Particle detector<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-size: 12pt; font-family: tahoma, arial, helvetica, sans-serif;\">Accelerators in CERN increase the speed of particles to high velocities and energies before they collide within the particle detector. The particle detector identifies information about particles including speed, mass and charge. Scientists use this information to identify these particles.<\/span><br \/>\n<span style=\"font-size: 12pt; font-family: tahoma, arial, helvetica, sans-serif;\">Most of the particles resulting from the collision move in straight lines. The magnetic field causes it to move through the curvature of the path, The electromagnetic fields within the detector work to erase that effect and maintain the straight paths of the particles.<\/span><br \/>\n<span style=\"font-size: 12pt; font-family: tahoma, arial, helvetica, sans-serif;\">Modern detectors consist of successive layers of sub-detectors.

Both methods rely on measuring the radiation emitted from the charged particles.<\/span><\/p>\n<p><span style=\"font-size: 12pt; font-family: tahoma, arial, helvetica, sans-serif;\">When a charged particle passes through a medium faster than light, it emits the Chernikov radiation at an angle dependent on its velocity.

And by measuring the momentum, we can calculate the mass of that particle and identify it.<\/span><\/p>\n<p><span style=\"font-size: 12pt; font-family: tahoma, arial, helvetica, sans-serif;\">When a fast charged particle crosses the boundary between electrical insulators with different resistance, it produces radiation that enables us to recognize its energy and identify it.<\/span><\/p>\n<p><span style=\"font-size: 12pt; font-family: tahoma, arial, helvetica, sans-serif;\">PraxiLabs provides you with the latest in <a href=\"https:\/\/praxilabs.com\/en\/blog\/2018\/01\/31\/past-present-future-virtual-reality\/\" target=\"_blank\" rel=\"noopener\">virtual reality<\/a> to enhance your teaching and learning experience.
