Video: LHC experiments prep for restart

02/23/15

Engineers and technicians have begun to close experiments in preparation for the next run.

The LHC is preparing to restart at almost double the collision energy of its previous run. The new energy will allow physicists to check previously untestable theories and explore new frontiers in particle physics.

When the LHC is on, counter-rotating beams of particles will be made to collide at four interaction points 100 meters underground, around which sit the huge detectors ALICE, ATLAS, CMS and LHCb.

In the video below, engineers and technicians prepare these four detectors to receive the showers of particles that will be created in collisions at energies of 13 trillion electronvolts.

The giant endcaps of the ATLAS detector are back in position and the wheels of the CMS detector are moving it back into its “closed” configuration. The huge red door of the ALICE experiment is closed up ready for restart, and the access door to the LHC tunnel is sealed with concrete blocks.
