An imaginary-/spl gamma//sub t/ lattice with dispersion-free straights for the 50 GeV high-intensity proton synchrotron

摘要

The 50 GeV proton synchrotron, proposed by the Institute of Nuclear Study of Japan (INS), requires zero-dispersion straight sections for polarized-beam operation. A new preliminary lattice that contains two straight sections with nonzero dispersion and two with zero dispersion is presented. The /spl gamma//sub t/ of the whole ring remains imaginary. Some analysis of the lattice is discussed.
