Heavy ion beam irradiation non-uniformity in inertial fusion

A non-uniformity of heavy ion beam irradiation onto a direct-driven fuel pellet in heavy ion fusion (HIF) is studied numerically. The energy deposition non-uniformity is investigated by several beam irradiation systems. The results demonstrate for the first time in HIF that the deposition non-uniformity can be reduced to low values, for example, less than 2% for a 32-beam irradiation system. [Copyright &y& Elsevier]
