Theoretical X-ray conversion efficiencies and spectra of single element plane targets heated by hundred picosecond light pulses from neodymium glass lasers

A non-LTE rate equation computer program was combined with a program which simulates the heating of laser heated targets in plane geometry. The hydrodynamic program calculates the absorption of laser light, the electron and ion temperatures-allowing for electron heat conduction-and the densities for each time-step and feeds these values to the rate equation program. The rate equation program gives to the hydrodynamic program for each time-step a source-sink term for each hot zone above 20 eV, representing the net emission and adsorption of X rays. The calculations presented involved approximately ten hot and ten cool zones.
