Summary

On September 27, 1993, the American Society of Mechanical Engineers conferred the designation "International Historic Mechanical Engineering Landmark" on the cryogenic system of the Tevatron, the world's highest superconducting synchrotron, developed at the US Department of Energy's Fermi National Accelerator Laboratory (Fermilab). Text of talk delivered at the designation ceremony by Dr William Fowler, Fermilab physicist and a significant contributor to the Tevatron's pioneering cryogenics, in which all the challenges faced by the cryogenic designers are recalled: scale of capacity, keeping the magnets all at the same temperature to within a fraction of a degree, etc. Years of design and field testing were necessary (from 1971 to 1983). From 1984 to 1989 the 24 expanders of the Tevatron accumulated one million hours of operation, with a mean time between failure of 8,300 hours, a remarkable result. J.V.
