Abstract

The invention relates to a plasma contactor, in particular to a plasma contactor combined with a hollow cathode electron generator and an annular ionization chamber, belonging to the field of gas discharge equipment. The ionization chamber is provided with a through hole at the center of the top end of the ionization chamber shell; The flange of the hollow cathode plasma contactor is fixedly connected with the shell of the ionization chamber through an insulating ceramic of the shell of the ionization chamber; A first permanent magnet is fixedly mounted on the inner wall of the top end of theionization chamber housing. A second permanent magnet is fixedly installed on the inner cylinder wall of the ionization chamber shell. The anode shell is an open hollow cylinder; The cylinder wall ofthe anode shell is fixedly connected with the mica sheet; The mica sheet is fixedly connected with the second permanent magnet; The invention can optimize the emission characteristics and reduce the transplant cost under different application situations. Under the same working condition, the potential difference can be reduced by about 40%.

Description

technical field [0001] The invention relates to a plasma contactor, in particular to a plasma contactor combining a hollow cathode electron generator and an annular ionization chamber, and belongs to the field of gas discharge equipment. Background technique [0002] The plasma contactor can inject plasma to the external environment, thereby realizing the physical process of charge exchange with the external environment, and its working external environment is generally a space environment. The emission characteristic is an important index to measure the working performance of the plasma contactor, which is the relationship between the potential difference of the cathode of the contactor relative to the external environment and the current of the emitted electrons. The application of plasma contactor puts forward strict requirements on its emission characteristics, that is, the potential difference under the rated emission current must be less than the required value. In or...
