A refrigerator inside CERN’s Large Hadron Collider (LHC) that cools helium from room temperature to 4.5 K (-268.65°C) has undergone major improvements in preparation for a new project.
The LHC is the world’s largest and most powerful particle accelerator designed to produce some of nature’s tiniest and most exostic subatomic particles by smashing protons together.
Housed underground, deep beneath the international border separating France from Switzerland, the LHC accelerates protons in a ring of superconducting magnets almost to the speed of light before they collide and explode, giving rise to particles possibly never seen before.
