Rock equation of state: a constitutive computer model

Description: A constitutive model for a rock equation of state was developed in HEMP and CEL-HEMP computer codes. The model includes the mechanical and thermal properties of soil, such as elasticity, pore closure, compaction, and vaporization. Three test problems were computed using the equation of state: ground motion following the LATIR event, impact vaporization of preheated plates, and surface motion produced from exploding a 3.7-kg(10-lb) charge at a depth of 6.5 m. Agreement between our computations f… more

High performance inertial fusion targets

Description: Inertial confinement fusion (ICF) designs are considered which may have very high gains (approximately 1000) and low power requirements (<100 TW) for input energies of approximately one megajoule. These include targets having very low density shells, ultra thin shells, central ignitors, magnetic insulation, and non-ablative acceleration.

Simulations of intermediate density laser fusion targets: recent progress in design and analysis

Description: The attainment of low-adiabat compression to high final state density is essential for achieving high gain thermonuclear micro-implosions. Using 1- and 2-dimensional numerical simulations with LASNEX, the target performance which can be expected and the limitations imposed by absorption heating, and transport for targets designed to reach 100 x liquid DT density (20g/cm/sup 3/) are discussed. The requirements imposed by the need for low preheat, adequate implosion symmetry, and the behavior of … more

Outline of a study of the energy needs, uses, and resources of developing countries and the implications for AID programs

Description: A study is outlined that will satisfy the requirement in the International Development and Food Assistance Act of 1977 for the President to carry out ''studies to identify the energy needs, uses, and resources that exist in developing countries.'' The study also considers those policies and programs in the energy area that can most effectively carry out the intent of the Act and the overall mandate of the Agency for International Development (AID).

Optical engineering problems associated with construction of the Shiva Laser Fusion Facility

Description: The Shiva laser system is part of a new 20 terawatt laser facility at Lawrence Livermore Laboratory. The system contains more than $5,000,000 worth of optics. This paper discusses the various optical components, typical component quantities and specification, and the problem of laser damage to components.
