Effect of pulsations of a plasma torch on the radial distribution of temperature

The influence of the pulsation of a plasma torch over the lateral intensity of the radiation and the radial temperature profile was studied. For the case of pulsation of the axis of a torch following a Gaussian distribution the exact integral equation was obtained relating the lateral intensity with and without pulsation. For a particular case the lateral distributions of radiation intensity were calculated for three different values of the Gaussian standard deviation. For the spectral line ArI 435.8 nm the radial temperature distributions with and without pulsations were calculated. The results show how pulsations can affect experimental results.
