Abstract
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 d istributions in appearance plasmas have been calculated by using the measur ed electric field strength and photo-radius. Then, radiation power has been calculated by making use of the radiation power density of high-temperatur e Ar and then compared with the measured radiation power as a function of p lasma length.
