Neutron yield in conic targets with additional laser fuel heating

The compression and the thermonuclear energy release in conic targets with additional laser heating are calculated. It is shown that irradiation of conic targets with a compound (long plus short) KrF laser pulse with energy 300 — 400 kJ can provide a neutron yield of ~10¹⁶ per shot and, accordingly, target energy gain coefficients above 0.1.
