-IV-l- IV. MEDIUM MOMENTUM, HIGH RESOLUTION BEAM (7.5 mrad) TM-223 2254 Description: The beam described is an unseparated charged beam with a maximum momentum of 120 BeV/c and a resolution of +0.04% proposed by the 1969 Aspen Summer Study 4 and designated as the 7.5 mrad beam in SS-37. A "Y" in the second section provides for two independent experimental areas. By using a tune, called tune 1, with a single intermediate focus and all bending magnets of the same polarity and another, called tune 2, with two intermediate horizontal foci and bending magnets of the second section in opposite polarity, momentum is recombined for both branches of the "Y" (SS-41). The element positions, lengths, excitations, and principal trajectories are given in Table I and Table II, The beam currently used for Area II studies employs more bending magnets than this one in order to fit it into the experimental area. been employed: The following principles of optimization have A. Copper coil front end quadrupolesof four- inch aperture and twelve-inch width described in SS-37 were assumed. The target to front end doublet distance is fixed to permit the mix of beams proposed in SS-37, B. The primary design goal is maximum resolution. 3
