A study program was carried out to evaluate the desirability for a 300- to 1000-Bev accelerator, to analyze various known detection and particle separation techniques and to develope techniques applicable at these energies, to estimate beam kinematics and the properties of the secondaries produced in a target, to design the experimental area and shielding required for such a machine, and to consider specific experiments that would be of specific interest in this energy region. It was found that, in application of such an accelerator, a good share of the experiments would involve secondaries of various energies up to the maximum energy of the machine. By extending the current techniques to the highest possible momentum, it would be possible to detect and identify particles in the 200-Bev/c region by means of a differentinl gas Cherenkov counter of approximately 100 ft in length. Developments were made on techniques for identifying and separating particles at high energies using the relativistic rise characteristics in ionization loss and the small angle strong interactions. Using kinematical considerations and assuming isotropy of the secondaries in the center of mass system, it was calculated that half of the secondaries produced would be contained inside a cone of half-angle of 4.5 deg at 300 Bev and of 2.5 deg at 1000-Bev incident energy.
