Abstract : The paper describes a new type of gas discharge tube which can be inserted horizontally into a circular waveguide to serve as a standard noise source. Operating in the 3-cm waveband with its terminal short-circuited, the discharge tube gives an excellent matching (VS-WR = 1.10 = 0.05) to the waveguide system and has a stable noise output of 18 = 0.5 db. The result of the present investigation is applicable to the development of noise tubes of the waveguide type for the wavelength regions below 8 mm and above 10 cm. (Author)
