  • The computer code Zgoubi calculates trajectories of charged particles in magnetic and electric fields. At the origin specially adapted to the definition and adjustment of beam lines and magnetic spectrometers, it has so-evolved that it allows the study of systems including complex sequences of optical elements such as dipoles, quadrupoles, arbitrary multipoles and other magnetic or electric devices, and is able as well to handle periodic structures. Compared to other codes, it presents several peculiarities: (1) a numerical method for integrating the Lorentz equation, based on Taylor series, which optimizes computing time and provides high accuracy and strong symplecticity, (2)more » spin tracking, using the same numerical method as for the Lorentz equation, (3) calculation of the synchrotron radiation electric field and spectra in arbitrary magnetic fields, from the ray-tracing outcomes, (4) the possibility of using a mesh, which allows ray-tracing from simulated or measured (1-D, 2-D or 3-D) field maps, (5) Monte Carlo procedures: unlimited number of trajectories, in-flight decay, etc. (6) built-in fitting procedure, (7) multiturn tracking in circular accelerators including many features proper to machine parameter calculation and survey, and also the simulation of time-varying power supplies. The initial version of the Code, dedicated to the ray-tracing in magnetic fields, was developed by D. Garreta and J.C. Faivre at CEN-Saclay in the early 1970`s. It was perfected for the purpose of studying the four spectrometers (SPES I, II, III, IV) at the Laboratoire National Saturne (CEA-Saclay, France), and SPEG at Ganil (Caen, France). It is now in use in several national and foreign laboratories. This manual is intended only to describe the details of the most recent version of Zogoubi, which is far from being a {open_quotes}finished product{close_quotes}.« less
  • This document contains operating instructions and system documentation for a computerized energy demand forecasting model. The model has the capability to forecast energy demand for four fuel types (electricity, gas, oil, and coal), for the three Northwest states (Washington, Oregon, and Idaho), in five-year steps, from 1980 through the year 2000. The forecasts are further broken down into the Residential, Commercial, Industrial, Transportation, and 'Other' sectors. The model is written in Fortran for the CDC 6500 computer. The model is econometric, correlating over 800 time series. The document also contains a Pacific Northwest Energy Data base plus a Data Basemore » Users Guide.« less
  • The purpose of this project was to design, develop, test, and document a computer simulation model of electric utility generating costs required to meet industrial power demands and the effects of load management on these generating costs. The development of this model and a model users guide to data preparation are included in this volume. (LCL)
