Diffusion estimation for small emissions. Preliminary report

Description: A simplified approach is presented to the calculation of ground level concentrations of effluents from small industrial and fuel burning installations. It is intended to serve as a first approximation to a very complex process. Because each stack, building, and terrain configuration is different, actual ground concentrations may frequently differ from the values calculated here by a factor of two. Nonetheless, this procedure should be useful for determining whether ambient air quality standards… more

SNAP 19 Pioneer F and G. Final report

Description: The generator developed for the Pioneer mission evolved from the SNAP 19 RTG's launched aboard the NIMBUS III spacecraft. In order to satisfy the power requirements and environment of earth-escape trajectory, significant modifications were made to the thermoelectric converter, heat source, and structural configuration. Specifically, a TAGS-2N thermoelectric couple was designed to provide higher efficiency and improved long term power performance, and the electrical circuitry was modified to yie… more

Cooperative geochemical investigation of geothermal resources in the Imperial Valley and Yuma areas. Final report

Description: Preliminary studies indicate that the Imperial Valley has a large geothermal potential. In order to delineate additional geothermal systems a chemical and isotopic investigation of samples from water wells, springs, and geothermal wells in the Imperial Valley and Yuma areas was conducted. Na, K, and Ca concentrations of nearly 200 well water, spring water, hot spring, and geothermal fluid samples from the Imperial Valley area were measured by atomic absorption spectrophotometry.

HIGH-INTENSITY EFFECTS IN THE LONGITUDINAL MOTION OF STORED PARTICLE BEAMS

Description: A brief review is given of the various self-field phenomena associated with the longitudinal motion of particles in storage rings. Although there are some high-intensity phenomena for which the coupling of longitudinal and transverse motion is essential, such as, for example, the headtail effect; the great majority of high-intensity phenomena primarily involve either longitudinal or transverse degrees of freedom. In this review, we restrict our attention to phenomena which are essentially longi… more

ELECTRON AVALANCHE IN LIQUID XENON

Description: We present detailed measurements of the electron avalanche process in liquid Xenon. The measurements were made by using liquid-Xe-filled proportional chambers with anode diameters of 2.9, 3.5, and 5.0 {approx} to detect 279-keV y rays and measure the photopeak pulse height as a function of applied voltage. The use of uniform pulses of electrons enabled us to discriminate against secondary Townsend processes. We present a table of the first Townsend coefficient a as a function of electric field … more

A proposal to study hard hadron - hadron collisions

Description: We propose a novel technique to study hadron-hadron collisions in which a significant fraction of the available energy is carried off in directions transverse to the beam. The technique is independent of the details of the final state so is ideally suited to searching for the jet-like particle clusters predicted by the parton model. The detector consists of a small calorimeter and several planes of 1 meter square proportional chambers.

HIGH-RESOLUTION LIQUID-FILLED MULTI-WIRE CHAMBERS FOR USE INHIGH-ENERGY BEAMS

Description: The authors describe experiments with liquid-xenon-filled wire chambers operating in the proportional mode and the difficulty of achieving useful gain when the anode wires have a spacing < 1 mm. As a result, they have largely turned our attention to chambers with closely spaced wires operated in the ionization mode. They have previously demonstrated a spatial resolution of 15 {micro} rms in this mode, using a 5-wire chamber and a collimated alpha source. They describe the construction of two… more

LIQUID XENON FILLED WIRE CHAMBERS FOR MEDICAL IMAGINGAPPLICATIONS

Description: In 1968, Luis Alvarez suggested that a high-resolution multiwire particle detector could be developed using a thin layer of liquified noble gas as the detection medium. After key problems in chamber construction, purification, and readout had been solved, a spatial resolution of 15 {micro} rms was demonstrated. Work is in progress to build high-resolution chambers and measure their properties for particle physics experiments at high-energy accelerators. The liquid xenon multiwire chamber also h… more

ELECTRONIC PROCESSES IN LIQUID XENON

Description: Several basic errors appeared in an article recently published by Prunier et al. entitled, 'Some Properties of Xenon Liquid-Filled Nuclear Detectors'. The article describes an experiment to measure electronic phenomena in liquid xenon using single wire cylindrical chambers. The author here describes some errors made in their interpretation of their experimental observations.

In-vessel transfer machine seal thermal analysis

Description: An analysis of the grapple drive stem temperature during operation of the IVTM (In-Vessel Transfer Machine) indicates that the maximum stem wall temperature at the seals will be 270/sup 0/F when the system is at dynamic thermal equilibrium. If the transfer operation is initiated with the grapple drive stem initially at thermal equilibrium in the lowered position, a pre-cooling step will be required if the maximum temperature of the grapple drive stem wall at the seals is to be limited to 300/su… more
