Title: Inertially confined fusion plasmas dominated by alpha-particle self-heating [Alpha-particle self-heating dominated inertially confined fusion plasmas]

Abstract

Alpha-particle self-heating, the process of deuterium–tritium fusion reaction products depositing their kinetic energy locally within a fusion reaction region and thus increasing the temperature in the reacting region, is essential for achieving ignition in a fusion system. Here, we report new inertial confinement fusion experiments where the alpha-particle heating of the plasma is dominant with the fusion yield produced exceeding the fusion yield from the work done on the fuel (pressure times volume change) by a factor of two or more. These experiments have achieved the highest yield (26 ± 0.5 kJ) and stagnation pressures ( ≍ 220 ± 40 Gbar) of any facility-based inertial confinement fusion experiments, although they are still short of the pressures required for ignition on the National Ignition Facility (~300–400 Gbar). Finally, these experiments put us in a new part of parameter space that has not been extensively studied so far because it lies between the no-alpha-particle-deposition regime and ignition.

Table 1 Table 1: Table of input and derived yield amplification metrics. Column 2 is laser energy absorbed (incident-backscatter) by the hohlraum (typically 10-15% of this is absorbed by the imploding capsule). The ablator mass (Column 3), mabl, is generally reduced to 5-10% of this value at peak implosion velocity. Column 4more » is the deuterium-tritium fuel mass loaded into the capsule. Column 5 shows the α-heating yield increase determined from the dynamic model (dm) while column 6 shows the same quantity calculated using the method of references.« less
