NTC-22.01.34 “Electron work function of a metal”

Br0.00

The training laboratory system is designed to estimate the work of electrons release from cathode material (tungsten) by the method of Richardson’s straights.

Structurally, the training system is a desktop unit.

The system consists of the case with following equipment:

vacuum diode with oxide tungsten cathode;
stabilized power supply that provides the necessary power to all circuit elements;
control scheme of the required parameters.

The front panel includes:

indicator to display the experimental data;
potentiometers for voltage regulation.

The back panel includes:

power switch;
USB socket;
fuse.

The stand is accompanied with a set of teaching materials and technical documentation intended for the teaching staff.

Experiments provided

Determinate the work of electron release from metal, using the current-voltage characteristic of a vacuum diode.
