SUPER SLOW EXTRACTION AT THE SSC USING CHANNELING IN A BENT CRYSTAL

The Possibility of a high-precision B-physics experiment in a fixed target configuration has stimulated considerable interest in the extraction of a low-intensity proton beam from the SSC during collider operation. The candidate scheme which has received the most attention uses a bent crystal of Si to deflect protons into the extraction line. In this paper, we present results on deflecting efficiency of Si(110) planes and on the feeding of the crystal by controlled injection of noise into the collider rf system. These results are important in establishing the viability of simultaneous collider and fixed target operation.
