Solid modeling research at Lawrence Livermore National Laboratory: 1982-1985

Description: The Lawrence Livermore National Laboratory has sponsored solid modeling research for the past four years to assess this new technology and to determine its potential benefits to the Nuclear Weapons Complex. We summarize here the results of five projects implemented during our effort. First, we have installed two solid modeler codes, TIPS-1 (Technical Information Processing System-1) and PADL-2 (Part and Assembly Description Language), on the Laboratory's CRAY-1 computers. Further, we have exten… more

Combination of artificial intelligence and procedural language programs in a computer application system supporting nuclear reactor operations

Description: A computer application system is described which provides nuclear reactor power plant operators with an improved decision support system. This system combines traditional computer applications such as graphics display with artificial intelligence methodologies such as reasoning and diagnosis so as to improve plant operability. This paper discusses the issues, and a solution, involved with the system integration of applications developed using traditional and artificial intelligence languages.

Real time analysis under EDS

Description: This paper describes the analysis component of the Enrichment Diagnostic System (EDS) developed for the Atomic Vapor Laser Isotope Separation Program (AVLIS) at Lawrence Livermore National Laboratory (LLNL). Four different types of analysis are performed on data acquired through EDS: (1) absorption spectroscopy on laser-generated spectral lines, (2) mass spectrometer analysis, (3) general purpose waveform analysis, and (4) separation performance calculations. The information produced from this … more

Distributed Implementation of Functional Program Evaluation

Description: In this paper, we explore the potential of the functional model, particularly as it pertains to architecture. In Section 2, we describe the graph-reduction operational model of computation and its relation to AI problems. In Section 3, we discuss a class of architectures that implement graph reduction and a prototype implementation in this class being developed at Los Alamos. Finally, we speculate on the applicability of graph reduction to some other classes of architecture.

Transient data acquisition techniques under EDS

Description: This paper is the first of a series which describes the Enrichment Diagnostic System (EDS) developed for the MARS project at Lawrence Livermore National Laboratory. Although EDS was developed for use on AVLIS, the functional requirements, overall design, and specific techniques are applicable to any experimental data acquisition system involving large quantities of transient data. In particular this paper will discuss the techniques and equipment used to do the data acquisition. Included are wh… more

DYNA3D, INGRID, and TAURUS: an integrated, interactive software system for crashworthiness engineering

Description: Crashworthiness engineering has always been a high priority at Lawrence Livermore National Laboratory because of its role in the safe transport of radioactive material for the nuclear power industry and military. As a result, the authors have developed an integrated, interactive set of finite element programs for crashworthiness analysis. The heart of the system is DYNA3D, an explicit, fully vectorized, large deformation structural dynamics code. DYNA3D has the following four capabilities that … more

Introduction to LINE: a Feynman diagram graphic generator

Description: This is an exec for making Feynman graphs of amazing complexity with amazing simplicity - once you know how. And knowing how is hopefully quite easy to learn. The LINE exec works iteratively, repeatedly prompting you for the elements of the graph. You tell the exec what kinds of lines (or loops) to draw, and where to put them. Each line is plotted in a 10 x 10 Cartesian coordinate system using two ordered pairs of coordinates, (x/sub 1/,y/sub 1/) and (x/sub 2/,y/sub 2/), as endpoints. The types… more

Computer aided design on the Tandem Mirror Experiment Upgrade (TMX-U)

Description: The Tandem Mirror Experiment-Upgrade (TMX-U) at Lawrence Livermore National Laboratory (LLNL) has been using a Computer Aided Design (CAD) graphics system to enhance its design capabilities since November of 1984. Three-dimensional models of the TMX-U magnet set, neutral beams, plasma, and containment vessel have been modeled on the system. These models are used for location verification, diagnostic placement, interference checking, and visualization of complex shapes generated on the Magnetic … more

Implementation and operation of VAX-based data acquisition system for the large coil task

Description: The VAX-based data acquisition system for the International Fusion Superconducting Magnet Test Facility (IFSMTF) at Oak Ridge National Laboratory (ORNL) is a second generation system that evolved from a PDP-11/60-based system used in the two-coil test and facility shakedown. The VAX 11/780 processor has been interfaced through a CAMAC fiber-optic byte serial highway to five existing LSI-11/23 frontend processors through dataway access port (DAP) modules. The VAX CAMAC interface has permitted th… more

LEGS data acquisition facility

Description: The data acquisition facility for the LEGS medium energy photonuclear beam line is composed of an auxiliary crate controller (ACC) acting as a front-end processor, loosely coupled to a time-sharing host computer based on a UNIX-like environment. The ACC services all real-time demands in the CAMAC crate: it responds to LAMs generated by data acquisition modules, to keyboard commands, and it refreshes the graphics display at frequent intervals. The host processor is needed only for printing histo… more

Alternatives to mainframes for text and graphic publishing

Description: For the past 10 years large publication facilities have been using mainframe computers and laser output devices to set pages of type with graphics and even photographs imbedded in the text. Mainframe computers have some real advantages, such as software packages that produce beautiful graphs, very efficient word processing, and incomparable typesetting. But these computers are expensive to own and operate and would be overkill for the small publications shop. For a company that does not have $1… more

WOLF: a computer code package for the calculation of ion beam trajectories

Description: The WOLF code solves POISSON'S equation within a user-defined problem boundary of arbitrary shape. The code is compatible with ANSI FORTRAN and uses a two-dimensional Cartesian coordinate geometry represented on a triangular lattice. The vacuum electric fields and equipotential lines are calculated for the input problem. The use may then introduce a series of emitters from which particles of different charge-to-mass ratios and initial energies can originate. These non-relativistic particles wil… more
