To maximize the versatility of the experiment, we can create a vacuum enclosure with ultra-high vacuum fixture feedthrough. This allows the cavity to be clamped onto the mounting block, protecting the cavity and maintaining alignment, while keeping the system in a vacuum state during gentle movement or local transportation within the laboratory.
