HIB illumination on a target in HIF

Three-dimensional computer simulations are performed for a heavy ion beam (HIB) irradiation onto a direct-driven spherical fuel pellet in heavy ion fusion (HIF). In addition, the non-uniformity growth due to a little pellet displacement from a reactor chamber center is investigated. The calculation results demonstrate that we can realize a rather low non-uniform energy deposition: for example, less than 2.0% even for a 32-beam irradiation system. Moreover, we developed the above simulation code for more common purposes in the research fields of medical treatment, material processing, indirect-driven HIF and so on.
