This paper describes the newly developed high current hollow cathode source as a soft X ray and vacuum ultraviolet spectral radiation transfer standard source.It consists of two anodes
a cathode and a two stage differetial pumping unit operated at a constant current of 2A with helium or argon as buffer gas at pressures 10 Pa-100 Pa.Several spectral lines of ArⅠ
ArⅡ
HeⅠ
HeⅡ
AlⅡ
AlⅢ and AlⅣ appear at spectral range 13 nm-200 nm.The spectral radiance stability is better than ±1% and the reproducibility is better than ±5%.
