The charge of the electron, acc. busch
Supplier: ELWE LEHRGERAETEBAU KLINGENTHA
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.

Millikanapparat
Supplier: PHYWE
Equipment for demonstration of the quantum properties of the electric charge, as well as to determine the elementary charge. The experiment is easy to perform and suitable for both laboratory and demonstration using the Videoflex camera (765-1000). With the equipment, the elemental charge can be determined in 3 ways: change of charge by means of an alpha radiator, falling and rising speed with constant capacitor voltage and free voltage and falling speed without electric field.

Experiment kit, electric field lines
Supplier: PHYWE
For demonstration of electric fields between electrodes of different shapes. The electrodes have been applied in thin conductive layers on plexiglass plates and the field line images appear in groats placed in a cuvette with 1 to 2 mm castor oil (the cuvette is placed on the plexiglass plate). The cuvette has an annular electrode in the outer jacket and a 4 mm connection sleeve. The cleaning is easy when electrodes resp. plexiglass plate never comes into contact with the oil. Suitable voltage source: High voltage generator 0 to 25 kV or Van de Graff generator.

Wire beam tube e / m
Supplier: PHYWE
Ice cream sphere filled with noble gas of low pressure. The tube's two cylindrical necks are protected by plastic sleeves and are designed to fit in Helmholtz coils 765-1207. The tube is used to show how an electron beam is deflected in a magnetic field. If the tube is in a homogeneous magnetic field with sufficient strength, the electron beam becomes circular. The tube is equipped with an internal measuring scale with fluorescent markings at distances of 4, 6, 8 and 10 cm (2r) from the cathode. The tube is well suited for determining the charge-mass ratio of the electron with great accuracy.

Electron deflection tube D
Supplier: 3B Scientific
Highly evacuated electron tube with focusing electron gun and fluorescent screen (90×60 mm) inclined relative to the beam axis, so that the path of the beam can be seen and the effects of electric and magnetic fields can be studied. The electron beam can be deflected electrically in the electric field of the built-in plate capacitor, and magnetically by using an optional Helmholtz coil pair D. By adjusting the electric field so that it cancels the magnetic deflection, it is possible to determine the specific charge e/m and the velocity of the electrons.
