Tevatron particle collider retired

Guardian : After a 26-year career, Fermilab’s Tevatron collider is being retired. Completed in 1983 at a cost of $120 million, the Tevatron was the highest-energy collider in the world for 25 years. It lost that standing, however, when CERN’s Large Hadron Collider began operations in early 2010. In an article for the Guardian, Mark Lancaster, a member of the High Energy Physics Group at University College London, reflects on his 15 years working on the Collider Detector at Fermilab (CDF) experiment at the Tevatron. He discusses how the Tevatron made novel use of superconducting materials in its magnets and how it required the construction of the world’s largest cryogenic facility.
