In 1976 he was the first to propose to make colliding beams of protons and antiprotons using the large synchrotrons at Fermilab and at CERN. This work led to the discovery of the weak bosons at CERN in 1982. He developed several techniques for cooling intense beams of antiprotons. In 1980 he was awarded an IR100 award for the invention of a technique for high- efficiency collection of intense electron beams. Dr. McIntyre is an A.P. Sloan Foundation fellow, a Fellow of the American Physical Society, and he is listed in Who's Who in America.
