The transition at 116 MeV between tank 5 of Fermilab's 200 MeV H/sup /minus// linac and a proposed 400 MeV 805 MHz side coupled linac requires both longitudinal and transverse phase plane beam matching. The design of the transition section is based on a 90/degree/ longitudinal phase oscillation at intermediate gradient combined with a sufficient number of quadrupoles to match transverse beam ellipses and simultaneously limit extreme beam width in the matching process. Both doublet and FODO variants of the transverse matching are satisfactory in concept; the choice is part of current design work. 4 refs., 2 figs., 3 tabs.
