This is a technical engineering drawing showing specifications for a 3-cell niobium box cavity assembly with detailed cross-sectional views and dimensions. The drawing includes four different section views (A-A, B-B, C-C, and D-D) along with top and side orthographic projections showing precise measurements in millimeters.

The drawing contains important fabrication notes specifying that all components must follow Fermilab Specification E0001324 for materials, fabrication, cleaning, handling and packaging. Key requirements include: align holes in all parts, cleaning procedures for removing foreign materials must be approved, all design/assembly must conform to UHV standards, and electron beam welding specifications. The cavity material is specified as Niobium Type 5 RRR grade, with flanges made of Niobium 55/Titanium 45 alloy (1.33" Mini ConFlat). The total assembly length is approximately 245.34mm with individual cavity cell lengths of 60mm.
