A semi-analytical expression of absorption curve of x-ray intensity for determination of electron temperature in plasma

Using parameter of an absorber other than the real thickness, the absorption curve of the intensity of bremsstrahlung or recombination continuous X-rays from a plasma for determining the electron temperature is expressed in a simple analytical relation approximately. This relation can be used to determine the temperature and the proportion of each component, when the energy distribution of electrons in the plasma consists of more than two components in the form of a Maxwellian distribution. Some results of the calculation of the absorption curve are shown. (auth.)
