Reflecting on the Life of a Superconductivity Giant

Award-winning engineer and physicist Alvin Tollestrup, who played an instrumental role in developing the Tevatron as the world’s leading high-energy physics accelerator at Fermi National Accelerator Laboratory and founding member of the Collider Detector at Fermilab collaboration, died on Feb. 9 of cancer. He was 95.

Tollestrup led the pioneering work of designing and testing 1,000 superconducting magnets used in the Tevatron, which operated from 1983 until 2011 and for 25 years was the world’s most powerful particle collider. This was the first large-scale application of superconductivity worldwide.
