Closed bomb vessel for plasma diagnosis and density control method thereof

Abstract

The invention discloses a closed bomb vessel for plasma diagnosis. The closed bomb vessel comprises a combustion chamber, two closed devices, a plasma gas generation device, a pressure relief device and an optical visual window, wherein the combustion chamber is made of gun steel, the two closed devices are separately arranged on the two sides of the combustion chamber, the plasma gas generation device is arranged at one end of the combustion chamber and is also arranged inside the closed device at the end, the pressure relief device is arranged inside the closed device at the other end of the combustion chamber and is used for leading out a high-pressure gas in the closed bomb vessel, and the optical visual window is arranged at the top of the combustion chamber and is used for an operator to observe plasma distribution condition in the combustion chamber. By the closed bomb vessel, gunpowder can be detonated in a high-temperature and high-pressure closed environment, and plasma generated after explosion is collected; thermal ionization plasma is diagnosed by a spectroscopy method, the quality of gunpowder is adjusted, and thus, the plasma density is regulated; and the adjustment is accurate and rapid, and the maneuverability is high.

Description

technical field [0001] The present invention relates to the plasma diagnosis research technology, in particular to a closed blaster for plasma diagnosis and a density control method thereof. Background technique [0002] Plasma diagnosis is actually two steps: diagnosis and diagnosis. Diagnosis is more focused on practice, while diagnosis is more on analysis. Therefore, plasma diagnosis is to use some physical method to detect and then analyze to obtain some physical parameters of plasma. In layman's terms, plasma diagnosis is a process of making plasma from "invisible" to "visible". [0003] There are many types of plasma, and the methods for diagnosing different types of plasma are also different. Generally speaking, there are two methods of plasma diagnosis: contact diagnosis and non-contact diagnosis, which are distinguished according to different diagnosis methods. According to different diagnostic objects, plasma diagnostic methods can be divided into low-temperatu...

Problems solved by technology

[0008] Another object of the present invention is to use a spectral measurement system to carry out non-contact measurement through an optical window, which solves the problem in the prior art that the light collection of thermally ionized plasma is difficult when the gunpowder is detonated in a closed explosion chamber
