Abstract: An electron tube includes a microwave structure, an electron gun having a cathode-wehnelt assembly, with axis for providing a linear electron beam along the same axis in a circular cylindrical passage with axis of the microwave structure, the cathode comprising a centre of rotation of the beam on the said axis of the cathode. The electron gun and the microwave structure each comprise portions of spherical surfaces in contact inscribed on one and the same sphere of radius centred on the centre of the cathode so as to form a swivel for angular adjustment of the axis of the cathode and to make the axis of the electron beam coincide with the axis of the circular cylindrical passage of the microwave structure. Applications include microwave electron tubes such as travelling wave tubes and klystrons.
