Heavy Ion Fusion

In order to realize an effective implosion, the beam illumination non-uniformity and implosion non-uniformity must be suppressed to less than a few percent. In this paper, a direct-indirect mixture implosion mode is proposed and discussed in heavy ion beam (HIB) inertial confinement fusion (HIF) in order to release sufficient fusion energy in a robust manner. On the other hand, the HIB illumination non-uniformity depends strongly on a target displacement (dz) in a reactor. In a direct-driven implosion mode dz of ∼20 μm was tolerance and in an indirect-implosion mode dz of ∼100 μm was allowable. In the direct-indirect mixture mode target, a low-density foam layer is inserted, and radiation is confined in the foam layer. In the foam layer the radiation transport is expected in the lateral direction for the HIB illumination non-uniformity smoothing. Two-dimensional implosion simulations are performed and show that the HIB illumination non-uniformity is well smoothed. The simulation results present that a large pellet displacement of ∼300 μm is tolerable in order to obtain sufficient fusion energy in HIF.

Hydrodynamic Code

The symmetry of heavy ion driven inertial confinement fusion targets is investigated with a two-dimensional Eulerian hydrodynamic code. The importance of the beam geometry is studied. The HIBALL design in its present form seems to inhibit a spherical implosion of the target. It is shown that the beam angle in the HIBALL geometry should be about 35 degrees.

Potential Efficiency

The idea of using accelerators in the production of energy by inertial confinement fusion has been developed since the mid-1970s. The basic concept is to use accelerated beams of heavy ions to provide energy to implode and ignite a small fusion pellet. Accelerators have been seen as attractive for this application due to their reliability, high repetition rate, and potential efficiency. They are therefore competitive with high power lasers at least for the commercial production of electrical power. This review summarizes part of the development and scientific efforts directed toward this application, which has been realized over time to be an extremely demanding one. Here we focus primarily on the rf linac/storage ring driver system approach and summarize the specific development that culminated in the European HIDIF study of the late 1990s. We also discuss some of the relevant followup accelerator studies.
