Production of Neutral Photopions as a Function of Atomic Weight (open access)

Production of Neutral Photopions as a Function of Atomic Weight

Thesis discussing the relative yield of neutral pions from elements in a reaction "as a function of the quantum-limit energy (the maximum energy of the quanta in the bremsstrahlung beam) of the Berkeley synchrotron." Interpretation of the results leads to values for the mean free path for absorption of the neutral pions in nuclear matter.

Experiments on Polarization in Scatterig Deuterons from Complex Nuclei and in Proton-Proton Scattering (Thesis) (open access)

Experiments on Polarization in Scatterig Deuterons from Complex Nuclei and in Proton-Proton Scattering (Thesis)

Abstract: "The elastic double scattering of deuterons by complex nuclei has been investigated experimentally. Measurements were made on carbon, aluminum, and copper at around 157 Mev; on lithium, beryllium, and carbon at around 125 Mev; and on carbon and aluminum at 94 Mev. The expected tensor components of the deuteron polarization have not been observed. Measurements have been made of the differential cross section and vector-type polarization as a function of angle for the scattering of deuterons from the above elements, at the above energies. The observed polarizations were larger than would be expected on the basis of the individual nucleon-nucleus interactions. In a second experiment we measured the 169-Mev proton-proton polarization at 10, 15, 22.5, 30, and 35 in the laboratory system. The results indicate that partial waves up to and including L = 3 are important at this energy."

Macroscopic Properties of a One-Dimensional Plasma Confined by a Magnetic Field

Abstract: "The quantities of interest in a confined plasma include the electric and magnetic fields, current density, diffusion velocity, temperature, pressure, and particle density. Equations governing the distribution of these seven variables are given in this report and special cases of a one-dimensional steady-state plasma are examined in detail. The solutions are given in graphical form."

Scatterbrain: An Automated Experiment on the 90-Inch Cyclotron

Summary: By controlling certain elements within a vacuum chamber from an external station, a charged particle experiment is performed without opening the chamber, thereby saving considerable time and labor. By pre-programming the experimental sequence on the external controls, the experiment can be performed from beginning to end with a minimum of operator attention. The data collected can be read out automatically on a punched paper tape for subsequent transmission to a digital computer.

Neutron Production in the Pinch Due to Instability Breakup (open access)

Neutron Production in the Pinch Due to Instability Breakup

Abstract: "The neutrons from the linear pinch in Berkeley have been shown to originate from deuteron collisions with a large net center-of-mass velocity in one direction along the axis of the pinch tube. The interpretation of this result is that the neutron production associated with the pinch is non-thermonuclear in origin. The object of this paper is to review the experimental evidence and discuss a possible source of the neutron production."

Energy Transfer Between Modified Maxwell Distributions

Abstract: "A particularly conventional modified form of Maxwell distribution is chosen. The modified expressions for (a) the energy transfer from the ions to the electrons in a plasma and (b) the brehmestrahlung from the electrons are calculated. Using the expressions some possible steady-state conditions for the ion and electron gases are derived and compared with those for the usual Maxwell distributions."

From abstract: "The purpose of this note is to consider the feasibility of conducting kiloton-weapons tests in underground holes sufficiently deep so that the explosion will be effectively contained. Such a shot would have the advantage that it could be detonated independently of weather conditions, and thus would allow greater freedom in the test program."

Introduction: A proposal for using an energetic neutral deuteron beam for injection into a mirror machine has been made by Eugene Lauer. This report describes an experimental attempt to produce a large neutral deuteron beam. The beam from the NTA ion source was passed through a target of hydrogen gas where the charge exchange mechanics produced a beam of energetic neutral deuterium atoms.
