The 9,300 magnets inside the 27 km (approx. 17 miles) circumference of the Large Hadron Collider are designed to be refrigerated for operational use. 10,080 tonnes of liquid nitrogen are needed to cool them down to just -193.2 C, before they are filled with nearly 60 tonnes of liquid helium, which cools them further to just -271.3 C.
