Method and system for measuring electron temperature and plasma density in galatea magnetic well

Abstract

The invention discloses a method and system for measuring electron temperature and plasma density in a galatea magnetic well. The system comprises a Langmuir probe module, a peripheral circuit module,a signal selection module, a signal acquisition module and a signal processing module; the Langmuir probe module comprises a plurality of Langmuir probes arranged in an array mode, and the total number and the positions of the Langmuir probes are decided by the plasma distribution condition in the galatea magnetic well, the magnitude order of the electron temperature and the plasma density and spatial configuration of a magnetic field region; the peripheral circuit module is connected with the Langmuir probe module and is used for detecting a current signal in each Langmuir probe and a voltage signal at the two ends of the probe; the signal selection module is connected with the peripheral circuit module and is used for selectively receiving the current signals and the voltage signals ofthe Langmuir probes; the signal acquisition module is connected with the signal selection module; the signal processing module is connected with the signal acquisition module and is used for obtaininga characteristic curve of the Langmuir probes according to the current signals and the voltage signals acquired by the Langmuir probes and further calculating the electron temperature and plasma density of each channel. The method and the system are convenient, rapid, accurate, high in efficiency and high in reliability.

Description

technical field [0001] The invention relates to the field of plasma parameter measurement, in particular to a method and system for measuring electron temperature and plasma density in a Jiala Jieya magnetic trap. Background technique [0002] With the progress of society, people's consumption of fossil energy is also increasing day by day. The reserves of fossil energy are limited and the use will cause environmental pollution. Therefore, it is urgent to find an alternative energy with high efficiency and energy saving. On the road of new energy exploration, nuclear energy is favored by people because of its high-efficiency and green characteristics. Compared with other new energy sources, nuclear energy is not limited by geographical reserves and other natural conditions. More importantly, the energy contained in nuclear energy is very huge. It is no exaggeration to say that as long as nuclear energy can be well developed, human beings do not need to worry about future en...

Problems solved by technology

[0003] In the two utilization methods of nuclear fusion and nuclear fission, due to the technical limitation that the single-nuclear constraint problem in the nuclear fusion process cannot be well solved, the nuclear power plants currently in operation all use nuclear fission to generate electricity. Radioactive waste, if an accident occurs, will cause catastrophic consequences. Not only that, the cost of extracting uranium 235, the raw material for nuclear fission, is high, which increases the cost of nuclear power generation
