Title:
METHOD FOR MEASURING PLASMA ION NON-EXTENSIVE PARAMETER
Document Type and Number:
WIPO Patent Application WO/2022/151982
Kind Code:
A1
Abstract:
A method for measuring a plasma ion non-extensive parameter comprising the following steps: using non-extensive statistical mechanics to describe a plasma, and deriving a formula describing a relationship between a geodesic acoustic mode frequency and the sound velocity of a plasma ion; collecting measurement data of a plasma temperature and the frequency of a geodesic acoustic mode in an apparatus where a plasma to be measured is located; utilizing the derived formula describing the relationship between a geodesic acoustic mode frequency and the sound velocity of a plasma ion to perform linear fitting on the measurement data of the plasma temperature and the frequency of the geodesic acoustic mode in the apparatus where the plasma to be measured is located, and obtaining a slope value; and numerically solving and obtaining an ion non-extensive parameter according to the derived formula and the obtained slope value in combination with a safety factor of the apparatus where the plasma is located. The present invention fills a gap in non-extensive parameter diagnosis where an electron non-extensive parameter can be measured using a non-extensive single electric probe, but a corresponding ion non-extensive parameter is unable to be diagnosed.
