Several experimental methods for temperature measurements are discussed with respect to their qualities as diagnostic tool for xenon plasmas in the pulsed mode. In this work the continuum radiation intensity corrected for infinite optical thickness is used for the determination of plasma temperature. An uncertainty δ T = 1,5% follows from a detailed error calculation. Results are given for p = 6 ⃛20 at and i = 1 ⃛3,5 kA/cm 2 . It is proposed to use a xenon pulse discharge as an calibaration standard for black body radiation at T ≈ 11000 ºK in a special pressure range where the plasma temperature is nearly independent on pressure.
