Inertiallyconfined, ignited thermonuclear D-T plasmas will produce intense blackbody radiationat temperatures T20 keV; it is shown that the injection ofGeV electrons into the burning core can efficiently generate high-energyCompton scattering photons. Moreover, the spectrum scattered in a smallsolid angle can be remarkably monochromatic, due to kinematic pileup;a peak brightness in excess of 10³⁰ photons/(mm² mrad² s 0.1% bandwidth) is predicted. Theseresults are discussed within the context of the Schwinger fieldand the Sunyaev-Zel'dovich effect.
