This volume of the LLE Review, covering the period January-March 2000, includes a broad range of topics being studied at LLE. The feature article is a report on OMEGA cryogenic target designs for the soon-to-be-commissioned OMEGA Cryogenic Target Handling System. The authors show that these targets are energy scaled from the NIF ignition designs and have similar 1-D behavior and stability properties.
Additional research highlights reported in this issue are:
- A numerical study of a novel laser-pulse modification for laser-imprint reduction in OMEGA cryogenic capsules.
- A report on experimentally inferred fast-electron preheat in direct-drive targets due to laser irradiation.
- A description of ongoing experimental and theoretical work relating to holographic grating design and fabrication.
- A report on simulations of laser smoothing in the absence of smoothing by spectral dispersion (SSD).
- A description of simulations of capsule implosions in tetrahedral hohlraum experiments carried out on OMEGA in a collaboration between LLE and Los Alamos.
- An article on measurements of the nanohardness of magnetic and nonmagnetic particles used in the magnetorheological finishing (MRF) process.
