An experimental method for the detection of the d(D,ɣ)He⁴ reaction has been developed. It involves the use of a double focusing magnetic spectrometer in conjunction with a solid state counter mounted in the focal plane of the spectrometer, the counter determining both the energy and dE/dx of the incident particles from the reaction. The design and construction of a particle beam handling system to guide the particle beam from the Van de Graaff generator to the object point of the spectrometer has been completed and tested. Using this beam, the characteristics of the spectrometer and solid state counter have been determined and recorded. An attempt was made to detect the d(D,ɣ)He⁴ reaction but no directly useful information on the reaction crossection was obtained. However, utilizing the knowledge gained during this experiment, it should be possible to make a more exacting attempt at the reaction crossection determination. / Science, Faculty of / Physics and Astronomy, Department of / Graduate

Aqueous precipitation of uranium as the peroxide has been used as a purification procedure since the early days of the Manhattan Project. The procedure has successfully produced an extremely pure product when handled in small batches. Heretofore peroxide precipitation has been utilized for relatively pure fuel from gaseous diffusion plants or in purifying column extraction products from salvage processes. A search of the unclassified literature had rendered no information upon the feasibility of separating fission products and fuel cladding materials by selective precipitation of uranium peroxide. The primary objective of this research was to produce a uranium oxide which is suitable free from nuclear poisons so that the uranium may immediately be refabricated for use as reactor fuel. The purified product must be decontaminated with respect to the radioactive impurities so that fuel fabrication may proceed with the use of standard fabrication techniques. The product of precipitation, uranium peroxide, should settle at a rate which will allow a continuous processing method to be employed. A secondary objective was to discover a technique which would improve the existing purification procedures presently in use substituting on precipitation where two or more are presently required. The effect of organic complexing on the settling rate of the precipitate was studied in an effort to improve the technology of single stage purification.
