Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Methods and techniques of spectral and laser diagnostics of plasma flows N.G. BYKOVA, V.A. VASILIEV, V.I. VLASOV, N.F. RUDIN, M.G. TRENEV, A.A. SHALAMOV The paper deal with methods for spectral and laser diagnostics of plasma flows applied to conditions typical in high-frequency induction plasmatrons. Presents a method of spectral measurement is implemented at the high-frequency plasma torch U-13HFP FSUE TsNIIMash with a capacity of 1 MW. The measurements shown in the working flow of the plasma torch with a nozzle 180 mm according to the method of the intensities of the spectral lines and the derived distribution of plasma temperature for the range of pressures P = 1...10 kPa and the capacity of the generator N = 100...300 kW. Keywords: high-frequency plasma torch, laser and spectral diagnostics of plasma flows. Contacts: E-mail: corp@tsniimash.ru Pp. 43-49.
