Electron beam recording device for HF signals

摘要

The recording device has an input block for the HF signals and an electron gun (4) providing an electron beam deflected on to a target provided by a piezodielectric recording plate (7). This cooperates with a pair of electroacoustic counter-rod transducers (8,9) on opposite sides, one acting as the HF signal input block and the other as the output transducer for reproduction of the recorded signals. A quadruple lens (5), coupled to a DC source (2) is inserted between the electron gun and the beam deflection system (6), its symmetry plane extending parallel to the rods of the counter-rod transducers.
