The X ray sources based on electron linac can produce X-rays with high energy, concentrated directions, and strong penetrating power, which have been widely applied in various fields. An electronic linear accelerator which has been built at present can provide an electron beam with energy of 120 MeV and pulse width of picosecond. The electron beam shooting at the metal targets can produce ultra-fast pulsed X-rays in the order of picosecond. In this paper, the pulse X ray characteristics are studied through simulating electron beam shooting at four metal targets with different thickness of Au, Ta, U, W and Pb by MCNPX program. The calculation shows that the X-rays can reach about 1010p/pulse and the pulse width can reach about picosecond level, when the pulsed electron beams with energy of 120 MeV ,charge of 0.5nC and pulse width of picosecond shooting at Ta targets. The yield and time width of pulsed X-rays are related to the diameter and thickness of the target.
