Calculation of the radiation power emitted from Ar long plasmas produced by a torch has been carried out.
At first, the radial and axial temperature distributions in appearance plasmas have been calculated by using the measured electric field strength and photo-radius. Then, radiation power has been calculated by making use of the radiation power density of high-temperature Ar and then compared with the measured radiation power as a function of plasma length.
