Background
The measurement of the gas thomson discharge parameters is mainly realized by a thomson experiment, which is a high-voltage physical experiment for researching the gas discharge development process and testing the dielectric property of the gas based on the thomson discharge theory. The main purpose of the experiment is to measure the thonson coefficient of the gas to be measured under different pressures. In the whole experimental process, the electrodes are arranged in a sealed discharge chamber, the sealed discharge chamber is made of 304 stainless steel, and the discharge chamber needs to be grounded for ensuring the safety and accuracy of the experiment. In order to prevent the high voltage lead and the high voltage electrode from discharging to the metal outer wall, a high voltage bushing is required to provide insulation to the ground. Because the gas content to be measured is less, the sealed discharge chamber needs to be subjected to high vacuum treatment before being filled with the gas, and the sealed discharge chamber needs to be kept at a lower pressure for a long time in the experimental process, the experiment has higher sealing requirements on any wall-penetrating connecting component including a high-voltage sleeve. In addition, during the test preheating process, it is necessary to supply initial electrons to the high-voltage electrode in the discharge chamber, and the electrons are generally generated by irradiation of intense ultraviolet light or intense laser beam on the metal film or electrode (electron transition).
In summary, when measuring the gas thomson discharge parameter, insulation and sealing requirements are satisfied, an electric path is provided for the electrode to establish an electric field, and an optical path is provided for the transition of the initial electrons.
