Detection And Analysis Of Spectrum In High Voltage Discharge Process Of Narrow Gap

The thesis is based on narrow gap high-voltage gas discharge process, detectand analysis the spectral characteristics in narrow gap gas discharge. Thenonlinear dynamics theory and method has been applied in gas medium dischargemechanism of theoretical research and experimental exploration. On the basis ofthe gas discharge and the particle transport theory, the gas discharge process ofnonlinear dynamic model is set up, by analysis the solution domain of this modelunder the different initial conditions, the nonlinear behaviour theory of gasmedium in discharge process has been given. Building the gas medium dischargeexperiment mode, and then carry out the experimental validation of gas dischargeprocess of nonlinear dynamic characteristics; Investigate the experimental resultof model detecting single variable time series phase space reconstructing gasdischarge process dynamics system of the method; Based on theoretical analysisand experimental results, based on the nonlinear dynamics theory of gasdischarge mechanism; Based on nonlinear system analysis method, research thenonlinear analysis of gas medium discharge process behaviour and itscharacteristics of narrative. This project intends to carry out the research workmentioned above for the feasibility analysis and argument.My research is focus on optical information acquisition during the dischargeprocess. Narrow gap discharge produces the electric spark, then the images ofdischarge and the intensity of illumination in different wavelength have beenacquired, establishing corresponding relationship with theoretical model,validation of gas medium nonlinear dynamic characteristics of the dischargeprocess, the plasma concentration of particles in the discharge process and thelight intensity corresponding relation, etc. For optical system design, includingthe front end of optical fiber collimating lens focusing system, optical fiber isapplied to realize long distance transmission, optical fibre and optical fibre spectrometer are linked together, through the CCD camera in the spectrometerspectral light at different wavelengths of light intensity, so as to complete a set ofoptical system, and then analyze the discharge mechanism and discharge opticalradiation and plasma concentration of relationship.
