Facile reaction/extraction of coal with supercritical fluids. Quarterly technical progress report, January 1-March 31, 1984

Description: Arylmethyl phenyl ethers undergo competing reactions when treated with Lewis acids in benzene solvent. Apparently, benzene is insufficiently reactive to compete with intramolecular (intrapolymer) nucleophiles and, consequently, no increase in solubility accompanies the cleavages of ether links upon addition of benzene. When better nucleophiles, naphthalene and phenanthene, are provided, carbonium ions generated from ether cleavages are capped and the product is lower in molecular weight and mor… more

Simulation program for central helium liquefier

Description: The computer program described here analyzes the performance of Fermilab Central Helium Liquefier (CHL) and predicts the values of the plant thermodynamic variables at all process points in the plant. To simulate CHL, this program is modified from the prototype program which was developed by Hitachi Ltd. a couple of years ago. This program takes care of only the steady state simulation and takes account of the change of the turbine efficiency, the pressure drops and the UA values of the heat ex… more

Operating procedures: Fusion Experiments Analysis Facility

Description: The Fusion Experiments Analysis Facility (FEAF) is a computer facility based on a DEC VAX 11/780 computer. It became operational in late 1982. At that time two manuals were written to aid users and staff in their interactions with the facility. This manual is designed as a reference to assist the FEAF staff in carrying out their responsibilities. It is meant to supplement equipment and software manuals supplied by the vendors. Also this manual provides the FEAF staff with a set of consistent, w… more

Automatic beam centering at the SSC interaction regions

Description: In the SSC interaction regions, the two colliding beams, each only a few microns in size, will have to be centered and maintained in good alignment over many hours, in order to provide the maximum possible luminosity and to minimize off-center beam-beam focussing effects. It is unlikely that sufficiently good alignment can be achieved without some kind of active feedback system, based on the beam-beam interaction rate. This memo describes such a system. In the proposed scheme, one of the beams … more

Modern solid state laser materials

Description: This document contains visual aids used in an invited talk entitled Modern Solid State Laser Materials, presented at the Conference on Lasers and Electro-Optics (CLEO) held in Anaheim, California, on June 20, 1984. Interest at LLNL in solid state lasers focuses on evaluating the potential of solid state laser media for high average power applications, including inertial fusion power production. This talk identifies the relevant bulk material parameters characterizing average power capacity and … more

Choice of Tevatron tune with matched low-. beta. insertions

Description: The Tevatron lattice, following closely the Main Ring lattice, is made up of approximately 90 FODO cells with six straight sections equally spaced. The straight sections are identical (neglecting the special high-..beta.. straight section used for resonant extraction) providing six-fold symmetry. Each straight section is comprised mainly of a pair of doublets, one at each end, in an antisymmetric configuration. The ..beta..-functions are matched to the building block cells but the dispersion fu… more

MOD silver metallization for photovoltaics. Quarterly technical report, December 1, 1983-February 29, 1984. [Metallo-organic decomposition]

Description: It was determined that pyrolysis products can produce dark surface films on MOD silver conductors. Improving the purity of all ink ingredients helped this problem. It was established that the existence and nature of the surface film is influenced by the rate of air flow during firing and by the heating rate in the 70 to 225/sup 0/C range, but these processing parameters have not as yet been optimized. Low temperature solvent removal was determined to be of prime importance in obtaining good adh… more

Fixed-fugacity option for the EQ6 geochemical reaction path code

Description: EQ3/6 is a software package used to model aqueous geochemical systems. The EQ6 code allows reaction paths of dynamic systems to be calculated. This report describes a new option for the EQ6 computer program that permits the fugacity of any gas in the EQ6 data base to be set to a fixed value. This capability permits simulation of the effect of rapid chemical exchange with a large external gas reservoir by allowing the user to fix the fugacities of selected gas species. Geochemical environments s… more

Control of Illicit Traffic in Dangerous Drugs

Description: Suppression of illicit traffic is only one aspect of the general Federal Government effort to prevent the abuse of narcotics and other dangerous drug;, but in political significance it is undoubtedly paramount. Various approaches to the problem have been suggested and tried since the first explicitly anti-opium law was enacted in 1887.
