Ersättningskrets för slanghållare S

The quality of the electron beam in electron defraction tube S (1013889) is affected by the resistance between sockets C5 (cathode) and F4 (heating filament) on the tube. For optimum results, the resistance needs to be 390 kΩ. Tube holder S (1014525) is accordingly designed such that this resistance is present. Older designs feature a […]

Övning Oscilloskop

Electron tube mounted on terminal base for investigating the design and operation of modern cathode ray tubes. The electron beam can be deflected by an electric field produced by the deflection plates integrated into the tube, and by a magnetic field from three external coils mounted on a ring. A Wehnelt cylinder is used to […]
