A 3.2 MeV injector has been designed and built for the DARHT II Project at Los Alamos Lab. The installation of the complete injector system is nearing completion at this time. The requirements for the injector are to produce a 3.2 MeV, 2000-ampere electron pulse with a flattop width of at least 2-microseconds and emittance of less than 0.15 pi cm-rad normalized. A large high voltage column has been built and installed. The column is vertically oriented, is 4.4 meters long, 1.2 meters in diameter, and weighs 5700 kilograms. A novel method of construction has been employed which utilizes bonded Mycalex insulating rings. This paper will describe the design, construction, and testing completed during construction. Mechanical aspects of the design will be emphasized. Work supported by the US Department of Energy under contract DE-AC03-76SF0098
