Super-Energy Accelerators

Alternating gradient synchrotron design can be extrapolated in a relatively straightforward way to larger circumference and higher particle energy. This means of increasing available energy is more attractive economically than any other accelerating system that has been suggested. Since increased energy makes it possible to uncover new phenomena as well as extend knowledge of effects presently known, a number of groups in the United States and Europe are intensively developing design studies of synchrotrons up to as large as 1000 GeV. This paper is a review of the work of these various groups, with particular emphasis on a 200-GeV study at the Lawrence Radiation Laboratory which will soon be presented to the Atomic Energy Commission.
