Burning the DT-plasma with inert impurities and non-cryogenic ICF-target with solid fuel

Abstract

The ignition criterion, ignition energy and gain of DT-plasma of ICF-target in the presence of impurities of light atoms such as beryllium, carbon and lithium at their arbitrary concentration are found. It is shown that the most promising type of non-cryogenic solid thermonuclear fuel is DT-hydride of beryllium (BeDT). It is suggested to apply the targets with such a fuel as: (1) Fast-ignited ICF-target at the ignition energy of 25–50 kJ and compression driver energy of 2–3 MJ; (2) ICF-target spark-ignited by 15–20 MJ heavy ion driver; (3) Spark-ignited target by 5–7 MJ laser as a neutron source for hybrid fusion-fission.
