Abstract:

Studies on non-LTE phenomena in laser heated plasma reported in DNA 3488-F have been continued. Some improvements of the LION rate code were made, including extension of the atomic model, and inclusion of a MHD model for the dynamics of a theta-pinch plasma. These are described in section 2. In section 3 the results of a parameter survey of X-ray conversion in Krypton are reported. It is found that there is an optimum ion density approx. 4 x 10 to the 16th power cu. cm, a minimum energy deposition approx. 1.5 x 10 to the 3 joulecu. cm, and that the pulse shape is of some importance. These results are discussed in some detail. The final section of the report contains a brief outline of a suggested technique for treating of radiation transfer in strong lines and coupling them to the non-LTE rate equations. This aspect of the work is very preliminary. Author
