About this file
This is a detailed engineering drawing for a 3-cell niobium cavity to be manufactured for Fermi National Accelerator Laboratory's Quantum Computing project. The drawing specifies a complex ultra-high vacuum device made from Type 5 RRR grade niobium with overall dimensions of 245.34mm length and multiple critical sections detailed in views A-A through D-D.
The manufacturing requirements include strict specifications for electron beam welding, acid etching, and cleanliness procedures detailed in Fermilab Specification ED0004662. All flanges must be made from Niobium 55/Titanium 45 alloy using 1.33" mini ConFlat specifications. Critical tolerances include ±0.1mm on general surfaces, Ra 1.6 surface roughness on internal surfaces, and Ra 0.8 specified for certain areas. The drawing includes multiple precision features including 7x Ø10mm holes, 3x Ø13mm holes with 10mm depth, and 36x R3.2mm radii. All components must be manufactured according to ultra-high vacuum practices and be free of contamination per Fermilab Specification ED0041324.
