Produsent: ELWE LEHRGERAETEBAU KLINGENTHA

Beskrivelse: The exercise oscilloscope is placed at the Helmholtz coils so that its main axis coincides with the axis of the coils. A sawtooth-shaped voltage is applied to the deflection plates of the oscilloscope so that a smooth horizontal line appears on the screen. Let direct current pass through the coils at a preset anode voltage and adjust the intensity of the current so that the line is focused at one point. The specific charge e/m of the electron can be calculated from the measured values ​​of the anode voltage and the current through the coil.

Produsent: PHYWE

Beskrivelse: Equipment for quantitative demonstration of the electron's wave nature and particle properties. At high electron energy, interference can be observed and evaluated in the form of Debye-Scherrer rings. The Broglie equation and Bragg's conditions can be proved. At low electron energies, the paticle properties of the electron can be demonstrated in a manner similar to geometric optics.

Produsent: 3B Scientific

Beskrivelse: Evacuated glass flask containing i.a. electron gun with directly heated tungsten wire cathode and a cylindrical anode. The electron gun emits a divergent electron beam, aimed at an Maltese cross of aluminum placed in the middle of the tube. The cross can be connected electrically. At the same time, light from the filament is also directed towards the cross, so that a comparison can be made between the shadows of different types that appear on the luminescent surface at the far end of the tube.
