Understanding of collision processes, which are induced by irradiation of neutrons and ions, is important for predicting the material performance in operational fission and proposed fusion reactors. Specially, an energetic primary knock-on atom (PKA) plays a crucial role in the production of collision cascade damage. The target of single phase TiD1.61 was irradiated by ion beams of 4He and 3He with energies of 50, 100, 150 and 200 keV. In the experiments with a 3He ion beam, the deuterium density in the target was monitored by the detection of a nuclear reaction of D(3He, p)α. A high energy primary knock-on process has been successfully observed by monitoring the nuclear reaction of D(d, p)t. Experimental results were compared with the results calculated by the Monte Carlo code TRIM. It was confirmed that the Monte Carlo code can successfully predict the production of energetic primary knock-on atoms under irradiation of the ion beam.
