SPARK-GAP-TRIGGER AMPLIFIER

Description: Short over-all time delay, low time jitter, and excellent long-term reliability are among the desirable features designed into a pulse generator that produces a 2-MW output pulse 30 nsec after the application of a 1-V signal at its 50-ohm input connector. The 10-kV output pulse can be used to trigger simultaneously several spark gaps of the type used in spark-chamber pulse modulators. The 10{sup 8} power gain of the spark-gap-trigger amplifier is achieved by four stages of amplification packageā€¦ more

A SPARK-GAP TRIGGER SYSTEM

Description: The construction and operation of a trigger system designed to fire a 30-kV 5000 A spark gap with a minimum delay following the arrival of a small signal pulse is described. In this particular experiment a 150-MeV/c muon is detected with scintillators on three 6199 phototubes, and the output pulse of the attached tunnel-diode triple-coincidence circuit is amplified and used to trigger the gap. Approximately 32 nanoseconds are needed from passage of the muon to the coincidence output, and approxā€¦ more

Electronic Computing Gage System for Monitoring Assembly Operations

Description: An electronic computing gage with IBM card punch was found to be a practical system for monitoring the critical steps in the crimping process of the assembly of some parts. In the crimping process a plastic part is compressed into a metal cup to obtain an assembled component without gaps. Dimensional data of the plastic part and metal cup are recorded on a printed tape and on IBM cards, which are used to program a computer to calculate the standard deviation of the lot. Lot acceptance is statisā€¦ more

Decommissioning of the Special Metallurgical Building at Mound Laboratory

Description: The Special Metallurgical Building at Mound Laboratory, a building of 18,515 sq ft of floor space, was decommissioned. This decommissioned facility formerly housed 238PU processes for the fabrication of radioisotopic fueled heat sources. The 238PU work was conducted in 585 linear ft of gloveboxes occupying approximately 12,600 sq ft of the building. All of the gloveboxes, process services, building services, interior walls, and ceilings were removed to the point of exit at the roof. Eighty-fiveā€¦ more

SNAPSHOT Safety Program Plan

Description: The SNAPSHOT Safety Program, as described in this document, is therefore formulated to align safety studies performed by separate agencies and their contractors. At the present stage in program development, the plan is principally concerned with the initial SNAPSHOT flight (SNAP 10A). SNAPSHOT represents a special flight mode for the initial reactors operated in space. The flights are designed to permit early space reactor tests prior to resolving all the safety proglems that may be associated ā€¦ more

Artificial Heart Pump (Additional Endogenous Heat) Program

Description: Three plutonium-238 radioisotope-powered heat sources were developed and fabricated at Mound Laboratory for use by Thermo Electron Engineering Corporation (TEECO) in the Artificial Heart Pump (Additional Endogenous Heat) Program. These sources contained doubly encapsulated plutonum-238 metal; two had a thermal power of 15(+2-0) W and one had 25(+0-2) W. Details of the design, fabrication, and testing of the heat sources are given in this report. Two of the heat sources (one 15-W and one 25-W) wā€¦ more

LAWRENCE RADIATION LABORATORY COUNTING HANDBOOK

Description: The Counting Handbook is a compilation of operational techniques and performance specifications on counting equipment in use at the Lawrence Radiation Laboratory, Berkeley. Counting notes have been written from the viewpoint of the user rather than that of the designer or maintenance man. The only maintenance instructions that have been included are those that can easily be performed by the experimenter to assure that the equipment is operating properly.

Tungsten Cladding of Tungsten-Uranium Dioxide (W-UO2) Composites by Deposition from Tungsten Hexafluoride (WF6)

Description: ļ»æA program is being conducted to develop a process for cladding tungsten and tungsten cermet fuels with tungsten deposited from the vapor state by the hydrogen reduction of tungsten hexafluoride. Early work was performed using recrystallized, high purity, commercial tungsten as the substrate material. Temperatures in the range 660 to 12950F (350 to 1700Ā°C) and pressures from 10 to 350 mm Hg were investigated. Hydrogen to WF 6 ratios of 10: 1 to 150: 1 were utilized. Efforts were directed towardā€¦ more
