The thermal ionization plasma generation test device comprises a closed explosion chamber, an optical fiber probe, a spectrometer, a sensor, a pressure regulation valve and a data processing system, wherein the closed explosion chamber comprises a combustion chamber, an optical window and an ignition device, a receiving port of the optical fiber probe is aligned to the optical window, the spectrometer is connected with the optical fiber probe and is used for data collection, the sensor is arranged inside the combustion chamber and can be used for measuring temperature and pressure in the combustion chamber, the pressure regulation valve is arranged at one end of the combustion chamber, and the data processing system is connected with the sensor, the pressure regulation valve and the spectrometer separately and is used for processing data and regulating plasma density. The invention discloses thermal ionization plasma density test and control methods. The thermal ionization plasma generation test device has the characteristics of simple structure of a test system, wide measurement range and the like and is convenient to use; and moreover, with the adoption of non-contact measurement, no interference is generated to plasma, accurate test also can be achieved in a high-temperature and high-pressure environment, and the plasma density can be regulated during the test process.

Description

technical field [0001] The invention relates to plasma diagnosis research technology, in particular to a thermal ionization plasma generation test device and its density test and control method. 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-tempe...
