Abstract:
To support the elliptical VSR cavities featuring five protruding waveguides, a spaceframe was engineered to serve a dual purpose: providing structural support and functioning as tooling during assembly. This spaceframe facilitates cavity rotation in the cleanroom, simplifying the installation of HOM loads and fundamental power coupler components. Designed specifically for the particular cavity geometry, the spaceframe has a diameter of 1.5m and provides axial and radial support for the cavity, along with its ancillaries, magnetic and thermal shields, and piping. A mockup assembly was conducted to evaluate the design’s functionality, assessing key aspects such as rotation and railing performance, cavity support and alignment, and the mountability and stability of ancillary components.
