An Investigation of Temperature Measuring Techniques for Use in High Power Density Nuclear Reactors

Description: Abstract: "Temperature measuring techniques for application to temperatures up to 2000 deg C have been investigated. Emphasis has been placed on those methods suitable for use in the environment of a high power density nuclesr reactor of particular design. A survey of available techniques is made and evaluated in the light of the general problem. The properties and behavior of materials at high temperatures and in a high flux of particle radiation are discussed. As a result of the preceding con… more

The Mechanism of Failure in Corona Discharge

Description: Abstract: "Experimental evidence is given which indicates that electronic bombardment is responsible for damage and failure of insulating material subjected to intense corona attack. The experimental revolts are further supported by some theoretical considerations of the energy-time properties of corona discharges."

The Method of Moments in Quantum Mechanics ; The [Pi]-Mesic Disintegration of the Deuteron

Description: The following report contains two reports to summarize a thesis: first, a report describing the classical moment techniques of Tchebycheff, Markov, and Stieltjes that have been applied to the problem of diagonalizing the Hamiltonian operator; and the second report describes an investigation of the higher-order corrections to the mesic disintegration of deuterons that is considered.

Microwave Diagnostics for High-Temperature Plasmas

Description: This report presents the high-temperature plasma research, aimed mainly toward controlled thermonuclear reactions, that have been greatly facilitated by the development of a number of microwave diagnostics, based on previous plasma microwave studies but mostly on ideas generated at UCRL in conjunction with the AEC Project Sherwood.

Nuclear Decay Schemes in the Actinium Family

Description: Abstract: "With magnetic alpha-particle and electron high-resolution spectrographs and scintillation gamma-ray spectrometers, a study was made of the nuclear decay of a number of members of the actinium family - U-235, Th-227, Ra-223, Em-219, Po-215, and Bi-211. Decay schemes are presented for each of these nuclides, together with such correlations as are possible with present theoretical nuclear models. The decay scheme of U-235 and a portion of that of Th-227 are interpretable in terms of the… more

Off-Gas Treatment in Berkeley Enclosures

Description: "In the past ten years quantities of alpha-, beta-, gamma- and neutron-emitting isotopes handled in enclosures have increased from microcuries to kilocuries. Contaminated-atmosphere problems have increased accordingly. Developments at Berkeley are reviewed with particular emphasis on recent equipment, viz: a multiple-purpose gas scrubber and a total-capture system for slug-dissolver off gas."

Peeler Extraction of a Synchrocyclotron Beam

Description: This report follows the study of a perturbation in the fringing magnetic field of a synchrocyclotron, using the computed unperturbed orbits of the modified Berkeley 184-inch synchrocyclotron, and introduces the peeler extraction to overcome limitations by using a perturbation that recedes with increasing radial amplitude.

Preferential Pumping and Its Application to the P⁴ Experiment

Description: Report analyzing the "preferential removal of neutral gas from an incompletely ionized plasma in which the ionized particles are allowed to drift along magnetic field lines through a differentially pumped channel" and its relation to the P⁴ experiment. The report also analyzes the regenerative and non-regenerative losses of plasma by radial diffusion, as well as "considerations relating to the ultimate disposal of overflow plasma."

Properties of Negtive K Mesons

Description: Report discussing interactions of 420-Mev/c K- mesons incident on a nuclear emulsion stack. Information on the differential scattering, elastic scattering, absorption events, and inelastic scattering of the mesons is provided. Additionally, the ratio of Λ to Σ hyperons produced in the primary interaction is calculated.

Pulsed Neutron Experiments With Fast Assemblies

Description: "The pulsed source technique consists of introducing repeated short bursts of neutrons into a subcritical assembly, and following the decay of the leakage flux as a function of time...It is noted that plotting the decay constant as a function of buckling gives an apparently accurate way to extrapolate to prompt critical. The pulsed source technique can also be used to calibrate control rod and poison worth, and will give some estimate of the prompt neutron lifetime."

Radiative Capture of Protons in Ne²⁰

Description: Abstract: "A preliminary measurement of the Ne²⁰(p,γ)Na²¹ reaction cross section has been made. Targets were prepared by bombarding aluminum targets with neon ions. The neon concentration in the target was determined by elastic scattering of 1.5-Mev-protons. The yield of positrons from the reaction Ne²⁰(p,γ)Na²¹(β)Ne²¹ was identified by the 23-second half life of Na²¹."
