Experimental study of characteristics of backstreaming ions based on information fusion

This paper briefly introduces the detecting demand for the characteristic parameters of backstreaming ions, and analyses features of several detecting methods. The integration experiment scheme of ion detection is designed. Three experiment methods and the analysis process of the test result are introduced. The methods adopt laser interferometer plus framing camera, Faraday cup and solid tracking detector, respectively. The original test data of the methods are analysed. Based on the information fusion technology, the analysis results are fused and the all-around analysis conclusion is obtained about the variety, motion velocity, density, etc. of backstreaming ions.
