Indirect-drive ICF target concepts for the X-1 Z-pinch facility
- Sandia National Labs., Albuquerque, NM (United States); and others
The authors describe designs of hohlraums and capsules for both ignition ({approximately}1--10 MJ) and high yield (up to {approximately}200 MJ) Z-pinch driven indirect-drive ICF concepts. Two potential Z-pinch hohlraum configurations: (1) the static wall or on-axis hohlraum; and (2) the imploding liner or dynamic hohlraum are considered. Both concepts involve cryogenic, DT-filled capsules ({approximately}2--4 mm in diameter) with Be or CH ablators (O, F, and Cu are currently being considered as dopants). Both types of hohlraums involve a Helium and/or CH foam fill. In the static wall hohlraum concept, the ICF capsule is isolated from the x-ray generation region. Advantages in the areas of capsule drive symmetry and diagnostic access might be gained from this arrangement. In the dynamic hohlraum, the ICF capsule has a direct view of the stagnation radiation. The potential advantage would result from the higher x-ray intensity and larger total capsule absorbed energy.
