The present condition of technique research on generation of intense pulsed super-hard X-ray via bremsstrahlung of pulsed intense-current pinched electron beam was described. The characteristics of a few main techniques to generate intense pulsed super-hard X-ray were compared, and the methods to increase the super-hard X-ray yield were analyzed. Making use of the MCNP code the relations of super-hard X- ray generation efficiency with tantalum radiating converter thickness in the electron energy range of 0.4～1.4 MeV were calculated. Moreover, the three experiment techniques for generation of intense pulsed super-hard X-ray on “QuangGuang-I” accelerator were introduced and the respective results corresponding to the three kinds of diode were: (1) the super hard X-ray energy density of 5
