This volume of the LLE Review, covering the period from April to June 2000, includes articles on direct-drive experiments performed with the enhanced beam uniformity now available on the OMEGA laser system (1-THz SSD with polarization smoothing). The feature article (cover and p. 181) concerns calculated performance of directly driven capsules on the National Ignition Facility (NIF).
Additional research highlights reported in this issue include:
- an experimental study of the effect of beam smoothing and pulse shape on imprinting
- an experimental study of direct-drive implosions of gas-fusion-fuel-filled capsules on OMEGA performed with 1-THz SSD, polarization smoothing, and high-quality power balance
- a study of secondary-neutron-yield measurement using current-mode detectors, and
- a description of a technique for measuring positional variations in target areal density using filtered x-ray framing cameras.
