The design of an X-ray converter for the BF-5 electron linear accelerator is described. First, the thickness of the converter is optimized by Monte Carlo simulations and the water-cooling structure of the converter is designed. Then, the water cooling process is simulated by finite element analysis and the temperature distribution of the converter is computed. Finally, the dose distribution of the converter as well as the energy spectrum of the generated X-ray is calculated. The results show that the maximal temperature of the converter is below 40 ℃, thus the converter could operate consistently and stably. The mean energy of the generated X-ray is 0.65 MeV, and the absorbed dose of the X-ray for the point 1 meter ahead from the center of the converter could reach 6 Gy/min.
