FIELD: instrument making.
SUBSTANCE: invention relates to electromagnetism and scientific instrument making. Device for studying the vacuum discharge of electrons in a vacuum field includes a magnet, above the pole of which is suspended a flat glass evacuated from within a cell with an autoemission cathode and an anode oppositely mounted from one edge of the cell and connected to the terminals of a Tesla transformer (Ruhmkorff coil), the primary winding of which is connected to the storage capacitor through a thyristor controlled from a series-connected clock generator with adjustable frequency and a thyristor trigger device, storage capacitor is charged via a resistor from a high-voltage power source, and the vacuum chamber suspended from the magnetic pole of the magnet from the side of the field-electrode cathode in the form of a needle and an anode is mechanically connected to the piezo pickup with its rigid fixed stop on the opposite side of the sensor, and the output of the piezoelectric transducer via a high-sensitivity pulse amplifier is connected to one of the channels of a two-channel oscilloscope, an additional output of the thyristor trigger is connected to its second channel.
EFFECT: study of the possibility of motion of a closed mechanical system under the action of internal force.
