Training Oscilloscope

• Demonstrate propagation of electron beams in free space or in E and B fields
• Measure the specific charge of an electron (e/m)
• Superimpose magnetic fields
• Demonstrate operation of a CRT

For investigating the design and operation of a cathode-ray tube. 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 focus the beam. A gas filling and fluorescent screen make it possible to observe the beam in the tube. A continuously adjustable saw-tooth generator can be used to analyze and visualize time-dependent processes. The device comes with a socket and printed wiring scheme.
