Abstract

At present there are two main problems in the ICF program. The first one is to define laser facility parameters and target design which can provide thermonuclear ignition. The second problem is to create such a facility with compact architecture and reasonable cost. The facilities existing at the national laboratories over the world cannot answer the first question. The reason is a too low level of laser energy. These facilities provide investigators with experimental data that serve for verification of the basic theoretical models for numerical simulations of thermonuclear targets. Figure 1 presents results of the study of the direct drive target compression using one-dimensional code SNDP [1,2]. These calculations show that a polymeric target could be ignited by the tailored laser pulse ofthe energy of 500 kJ at the wavelength of 0.35 μm. Gain factor in calculations is G=10 at the initial target radius of 1.5 mm, polymeric shell thickness of 33 μm and DT-ice thickness of 23μm. The essential fact is that volumetric compression necessary to achieve ignition is about 10⁴.
