Plenary Talk "Plans and Dreams for New Accelerators" Peter Limon ICMC Conference, Portland, OR, July 30, 1997

Plans are well advanced to build the Large Hadron Collider (LHC) at CERN, in Geneva, Switzerland. This proton-proton colliding beam storage ring has an energy of 7 TeV per beam. Hundreds of U.S. high-energy physicists will perform experiments at this facility, and a consortium of U.S. DOE national laboratories is collaborating in developing and building the challenging magnets for the experimental areas. A description of the machine and our work on it is presented.

At the same time, many plans are being developed for high-energy physics machines that will extend the anticipated results of the LHC. Such a large undertaking will have to be built in the context of a world-wide collaboration of scientists, industries and governments, and will have to take advantage of new technologies and new ideas to reduce its cost to acceptable levels. Studies of Very Large Hadron Colliders of about 50 TeV per beam, using superconducting magnets of high, moderate and low field strength are presented. A new and speculative type of machine, a Muon Collider could, in principle, be used to study the same phenomena as electron linear colliders in a more compact design. This machine presents many challenges, including high-field superconducting magnets that must operate in high radiation areas. Some of the features and design issues of a Muon Collider is discussed.
