摘要: Radiation effects have been studied in the modified 316L stainless steel and commercially available tungsten by heavy ion irradiation simulation positron annihilation lifetime techniques. The measured data show that radiation resistant property of steels is much better than tungsten, possesses best among them. present experimental results demonstrate for a beam window material an ADS spallation neutron source system, three.
