Aperture determination and operation simulation in large storage rings

Dynamic aperture is a well known and much used tool for collider design. However, for the SSC with its strong magnetic nonlinearities it is necessary to examine the nonlinear behavior of the beam more closely to minimize cost while assuring essentially linear behavior during routine operations. Thus the concept of linear aperture has been developed, and extensively applied in the design of the SSC. In order to explore this concept in a realistic situation, accelerator experiments have been proposed at the Tevatron which will test the parameters of the linear aperture definition chosen
