Exploring a Unique Vision for Heavy Ion Fusion

摘要

In 1996 and 1997 two studies of tritium-lean targets showed that large fuel assemblies with about 1% molar tritium fraction concentrated in a small DT spark plug surrounded by deuterium could achieve fuel energy gains of 500 and 1000 with isobaric and isochoric (fast ignited) hot-spot ignition, respectively, in both cases with sufficient net T breeding by D(d, n)T side reactions to avoid the need for any external T-breeding blankets. Those studies also noted the possibility of such targets providing more extra neutrons that could be used for additional breeding in external blankets, such as for fissile fuel production, and noted larger fractions of fusion yield in charged particles for direct conversion, compared to all-DT targets.
