As part of a two-beam accelerator research program /similar to/33 GHz accelerator sections have been designed and fabricated by both the machined-and-brazed technique and the electroforming technique. These procedures are summarized in this paper. Special requirements included a filling time of about 14 ns, +- 1.25 ..mu..m dimensional tolerances, input VSWR less than or equal to1.10, radial vacuum pumping for each cell, and a capability for a 200--300 MV/m accelerating gradient. A 34-cavity, 2..pi../3 mode, quasi-constant gradient, v/sub p/ = c, /similar to/10 cm-long, disc-loaded waveguide structure design and chosen with optimized sidewall input/output iris couplers. 13 refs., 5 figs., 1 tab.
