Fermilab shuts down Tevatron Injector

The Tevatron, the second highest energy particle collider in the world after the Large Hadron Collider (LHC),has finally ceased its operations at the Fermi National Accelerator Laboratory, Illinois on Friday.

The “energy doubler” accelerates protons and antiprotons in 6.28 km ring to generate energy of up to 1 TeV. Set up in 1983, the $270 million unit added its main Injector in 1994.

The Main Injector can accelerate particles up to 980 GeV. It uses 774 niobium-titanium superconducting dipole magnets cooled in liquid helium to hold the particles on track.

However, it said the unit had to shut down as it was made obsolete by the LHC which began operations last year. Tevatron is planning to use components in its main ring in other particle accelerators.
