| contents | A method for evaluating the radial temperature profile of a plasma channel is presented. The radiation spectrum of mixture of Hydrogen Nitrogen plasma in capillary discharge is collected. Assuming a local thermal equilibrium, the temperature is derived from the ratio of two emission lines (N +,N 2+). The method presented here does not rely on Stark broadening of the emitted H-alpha line hence can be utilized in a wide range of plasma constituents and densities, leading to an improved control of the plasma channel parameters as required by future laser wakefield acceleration schemes. |
