Difference orbits and BPM-resolutions

Description: In the interaction region of the SLC, the information of beam position monitors (BPM) is used to get crucial information on the beam parameters, like the position, the inclination, or the deflection of the beams at the interaction point. The information is usually extracted from the BPM readings by fitting orbits, using the known twiss parameters at the BPM positions. The quality of these fits depends, however, on the assumed resolutions of the BPMs. This is a particularly serious problem in th… more

Description of FEL3D: A three dimensional simulation code for TOK and FEL

Description: FEL3D is a three dimensional simulation code, written for the purpose of calculating the parameters of coherent radiation emitted by electrons in an undulator. The program was written predominantly for simulating the coherent super-radiant harmonic frequency emission of electrons which are being bunched by an external laser beam while propagating in an undulator magnet. This super-radiant emission is to be studied in the TOK (transverse optical klystron) experiment, which is under construction … more

Community Geothermal Technology Program: Hawaii glass project. Final report

Description: Objective was to develop a glass utilizing the silica waste material from geothermal energy production, and to supply local artists with this glass to make artistic objects. A glass composed of 93% indigenous Hawaiian materials was developed; 24 artists made 110 objects from this glass. A market was found for art objects made from this material.

Direct Catalytic Conversion of Methane and Light Hydrocarbon Gases Quarterly Report: Number 6

Description: The goal of this research is to develop catalysts that directly convert methane and light hydrocarbons to intermediates that later can be converted to either liquid fuels or value-added chemicals, as economics dictate. During this reporting period, we synthesized several phthalocyanine catalysts supported on magnesia (MgO) in Task 3. In Task 4 we have tested these catalysts for oxidation of methane and did a number of blank experiments to determine the cause of the low methanol yield we have ob… more

Maximum credible uranium-235 release from 211-H to the ETF

Description: The Effluent Treatment Facility (ETF) criticality review identifies two potential scenarios for criticality: (1) An instantaneous release of a significant quantity of fissile material from a process upset; and (2) A gradual accumulation of fissile material in process vessels. The potential for an instantaneous release from 211-H will be eliminated by the installation of a nuclear safety blank as recommended in the criticality review. With the nuclear safety blank installed, the only mechanism f… more

Critical process parameters for UCO kernel production

Description: UCO kernel fabrication was previously demonstrated at 2 kg per batch. The limiting factors were the size of the sintering furnace and the UCO drop columns. The former UCO drop columns also showed considerable variability in the quality of gelled microspheres. A larger-size sintering furnace and a set of drop columns with an improved design were installed in 1987. The new set of drop columns and sintering furnace, in conjunction with other modular-sized equipment, were designed to produce the re… more

Safe thickness for D1 dissolver with 1500 GM plutonium

Description: There is some concern that the FB-Line D1 dissolver may have been pressurized above the liquid head pressure by a reaction that occurred in the dissolver. The D1 Pu limit of 8.8 kg is based on a tank with an inner slab thickness of 3.34 inches and a wall thickness of 0.40 inches for a total slab thickness of 4.14 inches. When the incident occurred there was less than 1,500 gm Pu (1,323 gm) in the dissolver. Some calculations were made to determine the safe slab thickness for 1,500 gm Pu in the … more

Chloride content of dissolver solution from Rocky Flats alloy thirteenth campaign following head end treatment

Description: F-Canyon continues to obtain good chloride removal from Rocky Flats Alloy solution during head end treatment. One single batch of solution from the thirteenth alloy campaign, dissolved earlier this month, has been successfully processed. This was the first campaign to combine Rocky Flats Scrub Alloy (RFSA) with Rocky Flats Anode Heel Alloy (RFAHA) in the same dissolution solution (TA-2-1183). Following dissolution in Tank 6.4D, chloride was precipitated with mercurous ion added as the nitrate. … more
