1968 Week 5

SUPERCONDUCTING MAGNETS

(Fifth Week)

Chairman: W.B. Sampson, Brookhaven National Laboratory

Bill Sampson’s week on superconducting magnets was the most popular of the Summer Study. Superconducting magnets were described, from the huge affairs under construction for large bubble chambers to miniature units suitable for transport of particle beams. It was during this week that Peter Smith of the Rutherford laboratory brought forward his suggestions for stabilizing superconducting magnets and for reducing ac losses. These ideas already have inspired programs in a number of laboratories; thus far Smith appears to have been correct in all of his predictions.
