Mechanical Design and Fabrication of a Convectively Cooled Ion Accelerator for Continuously Operating Neutral Beam Systems

摘要

The details of a prototype 120 keV, 15 A accelerator designed for continuous operation are described. The molybdenum grids are convectively cooled by flowing water through individual grid rails and the thermal expansions are accommodated by the rail support modules. The design of these modules is such as to allow deflection and rotation at the grid rail ends, each rail being free to move independent of its neighbors. The results of structural analyses on the grids are presented along with the details of the fabrication techniques employed. A description of the cooling water system designed for this accelerator is also presented. (ERA citation 05:017242)
