Abstract

1365644 Waveguide windows; transit-time tubes VARIAN ASSOCIATES 4 April 1972 [5 April 1971] 15433/72 Heading HID and H1W A combined microwave window and transformer, for e.g. a pulsed microwave tube, comprises waveguides 5, 6 of unequal size extending from either end of a waveguide 2 larger than both and having a transverse seal 9 of, e.g. alumina displaced from the midlength position towards the smaller (5) of the two first waveguides. Waveguide 5 has a height h about one third its width and waveguide 6 a height about half its width. The seal 9 is displaced about 17% from the midlength position. The waveguide 2 may be circular and may have a length l about 85% of the free-space wavelength at midband frequency. The length d which includes the penetration of the pinging fields into the guides 5, 6 is n#/2 where # is guide wavelength and n is odd. The guide 5 is attached to the tube and the guide 6 filled with SF 6 under pressure.
