Collider detector beam line test table: a structural analysis

Description: The apparatus which sweeps calorimeter and endwall modules through the beam during testing is called a beam line test table. Because of rather stringent requirements for the physical positioning of the modules an analysis is done here to determine the modifications to the current test table design which will minimize deflections of the table under load.

Economic impact of an improved methanol catalyst. [Forecasting to 2000]

Description: The economic future of methanol is reviewed in light of its potential uses as a substitute for traditional hydrocarbon fuels and feedstocks as well as some evolving new uses. Methanol's future market position will depend strongly on its production cost in comparison with competitive products. One promising way to reduce the production cost is by use of an improved catalyst in the process by which methanol is obtained from the feedstock - which can be either natural gas or a similar product such… more

/sup 238/PuO/sub 2/ fines generation in radioisotopic heat sources

Description: Fuel aging studies were performed on the fuel form (plutonium-238 dioxide and yttrium) used in the Milliwatt Generator Radioisotopic Heat Source to determine the possibility of fuel degradation and of the resultant generation of respirable fines. In addition to long-term thermal aging of the fuel, evaluations included the effects of thermal ramping of the aged fuel to 1000/sup 0/C and of impacting thermally hot (450/sup 0/C) heat sources at 150 m/sec after thermal aging.

Seismic monitoring at The Geysers Geothermal Field, California

Description: Two distinct clusters of microearthquakes have been identified at The Geysers, possibly relating to two independent pressure sinks resulting from steam production described by Lipman, and others (1977). Unlike earthquakes in the Maacama-Rodgers Creek fault zone to the south and west, earthquakes at The Geysers are confined to depths of less than 5 km. The present level of seismicity at The Geysers appears to be higher than the preproduction level and is higher and more continuous than the seism… more

Measurement of critical temperature as a function of field

Description: The critical temperature has been measured for various magnet conductors as a function of the perpendicular applied magnetic field. The isothermal environment was provided by a variable temperature cryostat which fits into the bore of a 10.0 tesla solenoid. The temperature gradient across the sample volume was measured to be less than 25 millikelvins. The superconducting the normal state transition was measured resistively, using sample current densities from 0.01 to 2 A/cm/sup 2/. The maximum … more

Leaching study of nuclear melt glass: Part I

Description: Ground samples of three nuclear melt glasses from underground nuclear explosions at the Nevada Test Site (NTS) were leached at 25/sup 0/C with natural ground water from NTS. Using our dynamic single-pass flow-through leaching system we monitored the release of radionuclides from the glasses during 420 days of leaching. We continually flowed the ground water over the melt glass at flow rates of 185 ml/day for half of the samples and 34 ml/day for the rest. Leachate solutions were collected conti… more

The analysis of decontaminated defense waste salt supernate for I-129

Description: A method is reported here for the analysis of I-129 in decontaminated defense waste salt solution at concentrations as low as 0.14 pCi/ml. Repeated analyses have been unable to confirm the presence of I-129 in decontaminated samples of Tank 24 supernate.

BPMO HISTOS plots

Description: Early experience (1981-1982) with jittery position measurements in the CID (Collider Injector Development) and Sector 1 BPM (beam position monitor) system led us to ask whether the source of the observed noise was in the beam or in the BPM electronics. Prior to July, 1983, the signal from each BPM strip was individually processed. It occurred to us that the signal from each strip, when normalized by the sum of the signals from the two adjacent strips, made possible two independent measurements … more

Optimum operating temperature for accelerator diskloaded waveguide: test results from Sector 2

Description: To keep the accelerator structures in proper tuned condition with variable applied RF power, the Cu-temperature of the structures should be kept constant. From the specifications in CN 102, we derive that a ..delta../PHI/ = +-10/sup 0/ per ten-foot structure would be permissible to stay within a ..delta..E/E of 0.5%. Further measurements should be performed to prove that all structures stay within this limit under the SLC operating conditions where the average RF power level will be in the orde… more

Coordination of Federal Efforts to Control Illicit Drug Traffic

Description: This report discusses how best to coordinate the Federal government's multi-agency efforts to curb illicit traffic in dangerous drugs has once again become an issue of major interest to the Congress. Critics of the Reagan Administration's anti-drug program contend that it lacks an overall strategy and that it suffers from the absence of a central mechanism for the formulation of general policy as well as for the broad direction of operations
