Peeler Extraction of a Synchrocyclotron Beam (open access)

Peeler Extraction of a Synchrocyclotron Beam

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.

The Reactions of Mixed Crystals of Rare Earth Fluorides With Fluorine Gas (open access)

The Reactions of Mixed Crystals of Rare Earth Fluorides With Fluorine Gas

Thesis discussing the reactions of mixed crystals of rare earth fluorides with fluorine gas. The reactions were "studied gravimetrically by determining the weight increases of mixed tetrafluoride samples upon exposure to fluorine at a pressure of 1 atmosphere and a temperature of 250°C...The nature of the phases produced upon fluorination was studied by x-ray diffraction methods."

Utilization of the Surface Tension of Liquid Metals in Making High-Vacuum Seals (open access)

Utilization of the Surface Tension of Liquid Metals in Making High-Vacuum Seals

Abstract: "The free energy (surface tension) of a liquid film can withstand atmospheric pressure across a maximum theoretical gap of 10-(-3) cm between solids if the liquid wets and bridges the sides of the gap continuously. The eutectic alloy of Ga, lm and Sm is used for this purpose. This alloy is molten at room temperature with surface tension > 500 dynes/cm, vapor pressure < 10-(-8) cm at 500 C and excellent wetting properties. This alloy can be utilized in valves, motion seals, flanged joints and for electrical contacts mounted in any position. Using ultrasonic soldering techniques without heat or flux this alloy is readily wetted on W, Mo, Ta, pyrex, quartz and certain ceramics. These materials will withstand the corrosive action of this alloy at at least 400 C. Some de-wetting has been observed with only the nonmetals at high temperatures. This de-wetting may be due to thermal decomposition of gallium oxide. Stainless steel is easily wetted, but is attacked at temperatures above 300 C. Copper and brass are attacked at room temperature."

Cyclotron resonance absorption by a hydrogen plasma (open access)

Cyclotron resonance absorption by a hydrogen plasma

From introduction: "The work described in this report was undertaken as part of an experimental study to determine the effectiveness of radiofrequency field in heating the ions of a hydrogen or deuterium plasma. The ultimate aim is to find a method of heating a deuterium plasma until an appreciable rate of nuclear reaction takes place."
