In a detector preferably a parametric amplifier with a quadruple amplifying structure, the signal is detected by the interception over an incomplete portion of its path of rotation in a transverse plane of an electron beam velocity modulated by the signal in a cyclotron wave mode, the beam being subjected to an axial magnetic field. The interception structure is one or two plates at least one of which may be a group of plates, each having an aperture cut therein in the form of an Archimedean spiral. The input signal may be frequency modulated, amplitude modulated or the device may be used as a frequency changer and the device may be a linear or square law detector by suitably dimensioning the interception structure. The outputs of the two beam interception plates are combined. The quadruple electrodes, if provided, are hyperbolic. The input device is a Cuccia coupler or helix.

The latter change over may also be effected mechanically by causing a Schmitt trigger 28 to excite a member which reverses the rotation of the field of the motor. Two motors, each with a control circuit as above, may be employed to drive the X-ray tube in two directions at right angles, Fig. 1 (not shown), such that it describes a desired curve. The programme control for the two motors may be derived from a common pulse sequence via rectangular, triangular, and sinusoidal waveforms; alternatively, the control may be derived from the displacement of potentiometer settings by optical or mechanical scanning of two jigs representing the desired variation in time of the speeds in the two directions.
