Abstract:

The authors report theoretical and experimental work on the vaporization and heating of spherical overdense plasmas. Details of the required laser optics are described, together with charged particle, x-ray, and neutron diagnostics. A series of numerical experiments have been conducted to investigate the dynamics and neutron production in dense spherically symmetric plasmas. These have led to a development of scalings for energy absorption, shock strength and optimum neutron production. Similar numerical work has also been used to study the conversion of input laser radiation to output soft x-rays from an oxygen doped spherical laser plasma. The fast risetime of the calculated spectra suggests a method of producing a population inversion. Finally, the authors put forward one example of a breakeven configuration not requiring anomalous absorption. Author
