Modular design aspects of the FMIT drift-tube linac
The Fusion Materials Irradiation Test (FMIT) Facility drift-tube linac may be subject to high levels of activation because of distributed spill of the deuteron beam. The drift-tube suspension system will use a modular design to allow repairs and alignment to be made without manned entry into the tanks. Design details are presented that show the resulting high degree of flexibility. Because the accelerator will be installed at the Hanford Engineering Development Laboratory (HEDL) at Richland, Washington, it is desirable that large prefabricated tank assemblies (15 m and 18 m long by 2.5 m diameter) be delivered to the construction site. Stress studies and vacuum sealing tests have influenced the design and these results are given. The rf power dissipation in the tank walls is 1.5 MW and requires a high-capacity cooling system. Finally, rf tuning of the tanks is complicated by the presence of girder slots and open vacuum ports.
