Mechanical engineering

The major design work which received attention over the year was: the SSC injection and extraction collimators; the EP1 and EP2 probes; the septum magnet SPM2; the buncher; heads for the multi-head probes; supports for switching magnets; beam stops for the experimental beamlines; and a rotary target-handling system for isotope production. The major components that were manufactured, tested and installed during the past year were: the injection and extraction collimators; septum magnet SPM1 inside the SSC resonator; septum magnet SPM2 on the SSC extraction valley chamber; the electrostatic extraction channel on the SSC injection valley chamber; multi-head probes for the SSC; the high-energy beamline cooling water distribution system; the pneumatic system for the high-energy beamline diagnostic equipment; braces between SSC magnets; and axial graphite collimators. 5 figs
