This volume of the LLE Review, covering April-June 2005, features the following articles. ''High-Density and High ρR Fuel Assembly for Fast-Ignition Inertial Confinement Fusion'' by R. Betti and C. Zhou. In this article (p. 117), the authors optimize implosion parameters for fast-ignition inertial confinement fusion and design fast-ignition targets relevant to direct-drive inertial fusion energy (IFE). It is shown that a 750-kJ laser can assemble fuel with V_I = 1.7 X 10⁷ cm/s, a = 0.7, t = 400 g/cc, tR = 3 g/cm², and a hot-spot volume of less than 10% of the compressed core. If fully ignited, this fuel assembly can produce energy gains of 150. In the second article (p. 122), C. Stoeckl, T. R. Boehly, J. A. Delettrez, V. Yu. Glebov, J. Miller, V. A. Smalyuk, W. Theobald, B. Yaakobi, and T. C. Sangster, along with J. A. Frenje, C. K. Li, R. D. Petrasso, and F. H. Séguin (MIT), S. P. Hatchett (LLNL), and R. B. Stephens (GA) describe recent OMEGA experiments that have studied the fuel assembly of gas-filled, cone-in-shell, fast-ignition targets. Using both fusion products and backlit images, an areal density of ~60-70 mg/cm² was inferred for the dense core assembly. The results are promising for successful integrated fast-ignition experiments on the OMEGA EP facility, scheduled to be completed in 2007. Other articles are titled ''Planar Cryogenic Target Hangling Capability for the OMEGA Laser-Fusion Facility''; "Fourier-Space, Nonlinear Rayleigh-Taylor Growth Measurements of 3-D Laser-Imprinted Modulations in Planar Targets''; ''Technologies for Mitigating Tritum Releases to the Environment''; ''All-Solid-State, Diode-Pumped, Multiharmonic Laser System for Timing Fiducial''; and ''EXAFS Measurement of Iron bcc-to-hcp Phase Transformation in Nanosecond-Laser Shocks''.
