Function and Applications

Electron tube on a base with connection sockets for examining the structure and operation of a Braun's tube. The electron beam can be deflected in the electric field by the built-in plates inside the tube and in the magnetic field by three external coils mounted on a ring. A Wehnelt cylinder is used to focus the beam. The observation of the beam in the tube is realized by a gas filling and a fluorescent screen. Time-dependent processes can also be examined and displayed using the continuously adjustable sawtooth generator. Including socket with printed wiring.
