Description

For investigating the characteristics of electron beams as well as for demonstrating the structure and the mode of operation of a Braun tube. A gas filling of neon and a fluorescent screen allow the observation of the jet in the tube and on the screen. Deflection of the electron beam in the electrical field via integrated deflecting plates, in the magnetic field via external coils. Focusing of the jet by means of a Wehnelt cylinder. With integrated generator for the generation of a sawtooth voltage.
