- Excitation Functions for Reactions of Bev Protons on Indium (Master's Thesis)
- Abstract: "Indium was bombarded with protons in the energy range 2 to 6 Bev. Cross sections are reported for the (p,px+), (p,pn), and (p,p') reactions, as well as those for the formation of Be-7 and several neutron deficient isotopes of cadmium and indium. It was found that the (p,pn) yield increases slowly in the energy range 2 to 6 Bev, while the (p,px+) and (p,p') yields are approximately constant. The variation of the (p,pn) and (p,px+) yields with target thickness is discussed. The yields of several isomeric levels are correlated with their nuclear spin."

- Effects of Ionizing Radiation on Choline Chloride and Its Analogs
- Abstract: "Choline chloride and six analogs have been exposed in the dry, crystalline state to high-energy electron and gamma radiation. This investigation has confirmation the abnormal radiation sensitivity of choline chloride. Its G values (molecules decomposed/100 ev) were found to be: e- -radiation, 20; y-radiation, 175. These high values indicate a chain mechanism for the solid-state reaction. The G values for the choline analogs were found to range from 1 to 18 for the electron irradiations and from 1 to 32 for the gamma irradiations. Betaine hydrochloride approaches choline chloride in instability toward high-energy electrons but is far more stable in the presence of y-rays."

- Some Aspects of the Radial Stability in a Magnetic Mirror Machine
- Abstract: "The radial motion of an ion in an axially symmetric magnetic field is discussed. It is pointed out that particles of constant velocity have clearly defined upper limits to their radial motion. This is a result of the other constant of the motion, the canonical angular momentum. These limits are independent of the number of times an ion is reflected from the mirrors, providing the field is truly axially symmetric."

- Acceleration of a Plasma by Time-Varying Magnetic Fields
- Abstract: An application of the magnetic mirror principle to the acceleration of a plasma is described. It is shown that an axially symmetric magnetic field which increases with time but decreases with distance along the axis can impart a net translational energy to a plasma. This effect on a plasma is contrasted with that arising from an impressed electric field, which is not effective in producing acceleration.
- Measurement of the Behavior of a Plasma in a Magnetic Field by Means of Probes
- Abstract: "Probes were used to measure certain properties of the cloud of positive ions and electrons ejected from a pulsed ion source having two hydrogen-loaded electrodes. Time-of-flight measurements show: the presence of H+ ions with 50 ev directed energy; an increase of this energy with increasing pulse current in the source; a higher peak yield of ions with higher peak currents in the source; and higher yields and higher ion energies up to 110 ev have been recorded with the use of a pulsed magnetic field impressed upon the source. The neutral positive ion-electron beam from the source has been projected against an increasing magnetic field and the reflected and transmitted signals have been recorded and compared as a function of the magnetic field. Probe signals from the plasma as it encounters the magnetic field are oscillatory, suggesting that magnetohydrodynamic phenomena are presented."

- Abstract: "The reflections of microwaves from the walls of a plasma-containing vessel are studied. The probable cause of the reflections is discussed, and several suggestions are made for eliminating the reflections from the waveguide in the vessel and particularly from the pyrex vessel wall and copper tubing surrounding the pyrex. Quarter-wave-thick carbon-filled plastics or glasses having a very low vapor pressure room most promising when placed inside the pyrex cylinder. BaTiO3 appears to be an excellent material when placed outside the vacuum."

- 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."
