Mechanical Engineering Department quarterly report, April--June 1976. [Overview of MX engineering program; magnet system, injection system, vacuum system, and facility]
The proposed magnet system for MX will provide a minimum-absolute value B magnetic well with a 2-T central field, a vacuum mirror ratio of 2, and a mirror-to-mirror length of 3.4 m. The system will consist of a superconducting magnet in a displaced Yin-Yang configuration. Final design of the system requires analysis of the confinement field and the magnetic field and forces; development of the superconducting coil; and consideration of magnetic structure, fabrication, and installation. The MX injection system consists of the neutral-beam sources and beamlines, to build up and sustain the plasma, and the target-plasma generator, to create the initial plasma. The neutral-beam system is based on a design proved in 2XIIB, with modifications to provide increased extraction potential, ease of maintenance, and flexibility. The primary vacuum system for MX is designed to pump the molecular gas introduced by the ion sources, the neutral-beam particles that penetrate the plasma, and the mirror leakage particles. The vacuum regions are the injector-dump tanks, the end regions, and the side region around the plasma chamber. Liquid-helium-cooled cryopanels, shielded by liquid-nitrogen-cooled chevrons, do the pumping. The MX facility will include a structure to house the MX machine and its attendant diagnostics and power supplies, a cryogenic refrigeration system, and an external vacuum pumping system. Design of the facility requires a study of structural requirements, heat load, and source gas load.
