“…We presently see a reevaluation of the cluster ion beam (CIB) approach to ICF, including cluster ion acceleration, cluster fragmentation and target correlated stopping of cluster ions [87][88][89][90]. The CIB drive HIF demonstrates a potential for ICF through the enhanced and correlated ion stopping together with a lower q/A [87,88], which may relax the accelerator design further, compared with that for the conventional HIB accelerators. At the same time, the cluster ion source and the stable cluster acceleration should be further studied experimentally [90].…”

“…Studies at HIAF include EOS, material phase transitions, hydrodynamic behavior of matter, ion interaction with materials in the HED state [22]. At KEK, Japan, HEDP and ICF based on a cluster ion beam (CIB) are being considered [12,[87][88][89][90]103,116]. For example, Si clusters are efficiently formed in an ellipsoidal-shaped cell with a Si crystal at the focal point of the cell.…”

“…[87][88][89]118,119], cluster ion-based ICF is studied, though further studies are needed, including size distribution control of cluster ions, stable cluster ion acceleration and transport, cluster ion beam interaction with matter, etc. Relating to cluster ion interaction with solid material, correlation effect among ions of one cluster would introduce an enhancement of ion stopping power [87][88][89]. On the other hand, a peculiar ion-overtaking behavior between two Si ions of one Si cluster was also found in a Si-cluster solid interaction theoretically [90].…”

“…For the 8 GeV Pb+ ion, the stopping range is ~500-700μm in metal target materials. If heavy ion particle energy can be reduced significantly or correlation effect on cluster ion stopping power is enhanced [87][88][89][90]129], HIB ion stopping range would be shortened. In this case, it may be expected to increase the target material temperature and the radiation temperature, and the radiation energy would dominate the energy transfer in the target energy absorbing layer and in the implosion phase.…”

Direct-drive heavy ion beam (HIB) inertial confinement fusion (ICF), or HIF would be a promising future energy source for society. Particle accelerators produce HIBs with precise particle energies, pulse lengths and pulse shapes with high energy efficiencies of ~30-40%. Higher energy driver efficiency means that a lower fusion energy output is required to construct a HIF power station to supply ~1 GW of electricity. A HIF power station could use about 4 to 5 MJ of HIB energy per shot at a shot rate of ~10 Hz. This review is focused on the direct-drive scheme in HIF. In directdrive fuel target HIBs deposit their energy into a shell surrounded by a denser tamping outer layer. The DT (Deuterium-Tritium) fusion fuel, with a total mass of several mg, must be compressed to about one thousand times solid density to reduce the input driver energy and to achieve an adequate burn fraction. Highdensity compression is a major challenge in ICF, requiring that non-uniformity in driver energy deposition be kept lower than a few percent. The axis of an HIB can be made to oscillate sufficiently rapidly to improve the uniformity of energy deposition.
