Design and operation of the low-momentum beam are discussed. In the normal operating mode, the beam acceptance is calculated to be 21 msr percent $delta$P/P at 1 GeV/c. At 0.8 GeV/c, enriched kaon fluxes of 2940 K$sup -$ or 16,390 K$sup +$ are expected for 10$sup 11$ 12.3 GeV/c incident protons, while 420 anti p are expected at 1 GeV/c. In the reversed-polarity operating mode, the maximum beam acceptance is calculated to be 15.2 msr percent $delta$P/P; excellent momentum resolution is available in pion and proton beams which are run in this mode. Results indicate that the beam operates as predicted, with the exception of separator rejection factors. (auth
