A review of accelerators beyond 2000

Abstract

The development of the synchrotron, and later the storage ring, was based upon the electrical technology of the turn of this century aided by the microwave radar techniques of World War II. This method of acceleration seems to have reached its limit. Even superconductivity is not likely lead to devices which will satisfy physics needs into the 21st century. Unless a new principle for accelerating elementary particles is discovered soon, there is little hope high energy physics will continue to reach out to higher energies.
