Toward inertial confinement fusion energy based on heavy ion beam

Heavy ion inertial fusion (HIF) energy would be one of promising energy resources securing our future energy in order to sustain our human life for centuries and beyond. The heavy ion beam (HIB) has remarkable preferable features to release the fusion energy in inertial confinement fusion: in particle accelerators HIBs are generated with a high driver efficiency of ~ 30-40%, and the HIB ions deposit their energy inside of materials. Therefore, a requirement for the fusion target energy gain is relatively low, that would be ~50-70 to operate a HIF fusion reactor with the standard energy output of 1GW of electricity. The HIF reactor operation frequency would be ~10~15 Hz or so. Several-MJ HIBs illuminate a fusion fuel target, and the fuel target is imploded to about a thousand times of the solid density. Then the DT fuel is ignited and burned. The HIB ion deposition range would be ~0.5-1 mm or so depending on the material. Therefore, a relatively large density-scale length appears in the fuel target material. The large density-gradient-scale length helps to reduce the Rayleigh-Taylor (R-T) growth rate. The key merits in HIF physics are presented in the article toward our bright future energy resource.Comment: 17 pages. arXiv admin note: substantial text overlap with arXiv:1511.06508, arXiv:1608.0106

Researches on reactor core in Heavy ion inertial fusion

In Heavy ion inertial fusion (HIF), the issues include the generation and transport of heavy ion beam (HIB), the optimum pellet structure, the realistic nuclear fusion reactor design, etc. In this research, we have studied a conceptual design of a nuclear fusion reactor system in HIF (see Fig. 1)..

Target implosion uniformity in heavy ion fusion

It is well known that heavy ion beams (HIBs) have a high controllability, a high driver energy conversion efficiency and a high repetition rate. Wobbling HIBs are easily available as the energy driver in inertial fusion..
