Producing high energy photons using titanium PRS loads
- Naval Research Lab., Washington, DC (United States). Plasma Physics Div.
Because of the large amount of kinetic energy and mass needed for efficient production of K-shell emission from a high Z plasma, it is reasonable to assume that high Z experiments will take place at relatively low {eta} values, where {eta} is the ratio of the kinetic-energy-per-ion to the minimum amount of energy E{sub min} needed to ionize an atom to the K-shell in a thermal plasma. The earlier work made predictions for producing K-shell emission based on 1-D, radiative, magnetohydrodynamic, {eta} > 3, calculations. This has led them to perform similar 1-D calculations at {eta} values < 3 for titanium loads. The results of this work are applicable to future titanium experiments to be performed on the ACE IV machine. In some experiments it may be desirable to produce photons that have energies beyond which a specific machine is capable of efficiently producing K-shell emission. These photons might be produced either by recombination or line emission with the machine in an inefficient high Z scaling regime. These alternatives are examined by comparing theoretically the > 4 keV photon yield obtained by recombination from high {eta} argon load implosions to that generated by K-shell emission from low {eta} titanium implosions. Again, these calculations are for an ACE IV class machine.
