Compact toroid radiation production
- Phillips Lab., Kirtland AFB, NM (United States). High Energy Plasma Div.
The generation of copious quantities of high energy (100`s of kJ`s to MJ`s), high power (10`s of TW`s), multi-keV electromagnetic radiation is of great interest to the nuclear effects community. Currently extant sources of such radiation, however, are quite modest; for example, SATURN, the Sandia z-pinch driver, produces at best about 30 kJ of Ar K radiation (above 3 keV) and almost nothing above 10 keV. In an effort to approach the levels indicated above, the High Energy Plasma Division of the Air Force`s Phillips Laboratory has been investigating, both experimentally and computationally, the formation, compression, acceleration, and radiation production of compact toroid (CT) plasmas. The authors have considered the use of stagnating, high kinetic energy (2--10 MJ), high velocity (50--150 cm/{mu}s) CT`s as a source of radiation having the requisite energy, power, and spectral characteristics. To this end, they have performed a suite of calculations using the radiation hydrodynamics code LASNEX together with the non-LTE atomic physics package XSN-Q to estimate, for a range of achievable operating parameters, the radiation produced as a CT stagnates against a perfect wall, based on simple assumptions for CT dynamics. They find that for the parameters of the existing bank, a stagnating CT can be a very efficient emitter of Ar K radiation, with over a megajoule radiated in a 30 ns pulse. In addition, they find that with sufficient radial compression, a CT driven by the existing SHIVA-STAR can emit 10`s of kJ`s of Kr K radiation (12--15 keV) in a 10 ns pulse.
