Superconductivity applications in high energy physics

During the past five years, several very large superconducting bubble chamber and spark chamber magnets have become operational. The economic and other factors which have led to the construction of large superconducting solenoid magnets for high energy physics research are discussed, and the technological development which made these magnets possible is summarized. Much of the recent development work on superconducting magnets for high energy physics has been directed toward the next generation of accelerators and beam storage rings. Here the goal is to develop dipole and quadrupole magnets of high field precision, low cost, high reliability, capability for slow pulsing, and minimal sensitivity to radiation heating. The status of this work and its application to future accelerators is described. Also, the application of superconducting rf cavities for linear accelerators and particle separation is reviewed briefly.
