Abstract

Inertially confined, ignited thermonuclear deuterium–tritium plasmas will produce intense blackbody radiation at temperatures of $T\gtrsim 20\mathrm{keV}$; it is shown that the injection of GeV electrons into the burning core can efficiently generate high-energy Compton scattering photons, as the high blackbody photon density alleviates the small interaction cross section. Moreover, it is shown that the spectrum scattered in a small solid angle can be remarkably monochromatic, due to kinematic pileup; peak brightness in excess of ${10}^{30}\mathrm{photons}∕({\mathrm{mm}}^2{\mathrm{mrad}}^2\mathrm{s}0.1\%\mathrm{bandwidth})$ are predicted. These results are also discussed within the context of the Schwinger field and the Sunyaev–Zel’dovich effect.
