Problems solved by technology

In teaching and scientific research places, the existing gas discharge experimental equipment generally contains only one gas discharge vacuum tube, that is, one voltage source alone provides working power for one vacuum tube, and the discharge gas in the vacuum tube is fixed after the vacuum tube is made. , it is not easy to replace and replenish, and the vacuum degree in the vacuum tube will drop after a long time of use
This makes the equipment cost high, the experimental phenomenon is single, and the performance is unstable
If you want to observe different gas discharge phenomena, you need multiple experimental equipment, occupying the experimental site, complicated operation, and prolonging the experimental time

Abstract

The invention discloses a gas discharge experiment instrument, which is characterized by comprising an adjustable voltage source, a vacuum pump, a set of experiment vacuum tubes fixedly arranged on a bracket and a multipass connector arranged in a vacuum-pumping circuit, wherein electrodes at two ends of the vacuum tubes are arranged at a voltage output end of the adjustable voltage source in parallel; a main interface of the multipass connector is communicated with a vacuum-pumping port of the vacuum pump so as to form a vacuum-pumping main channel, and branch interfaces of the multipass connector are communicated with vacuum-pumping ports of the vacuum tubes in a one-to-one correspondence mode through corrugated tubes so as to form vacuum-pumping branch channels; and the set of the experiment vacuum tubes are vacuum tubes of the same type or of different types selected according to settings. According to the invention, a plurality of vacuum tubes are arranged on the same experiment device, the selected vacuum tubes are different in electrode materials, or electrode shapes or different types of discharge gas, and different gas discharge experiments are carried out continuously, thereby greatly saving the experiment field and the equipment cost.

Description

technical field [0001] The invention relates to a gas discharge experimental instrument, more specifically an experimental device for researching gas discharge phenomena in a vacuum environment, and is especially suitable as a teaching tool. Background technique [0002] Gas discharge is a common physical phenomenon. Depending on the degree of vacuum, gas properties, applied voltage, electrode shape, power input signal frequency, container and electrode materials, etc., gas discharge has various forms. The main forms are dark discharge, Glow discharge, arc discharge, corona discharge, spark discharge, high-frequency discharge, etc., the research on this phenomenon is of great significance. In teaching and scientific research places, the existing gas discharge experimental equipment generally contains only one gas discharge vacuum tube, that is, one voltage source alone provides working power for one vacuum tube, and the discharge gas in the vacuum tube is fixed after the vac...
