Technical Progress Report, November 1, 1979-October 31, 1980. Report Npl-865. [Univ. Of Colorado]

Description: Work carried out at the Nuclear Physics Laboratory of the University of Colorado from November 1, 1979 through October 31, 1980 is summarized. Emphasis was on light ion reaction studies with the AVF cyclotron. The high resolution magnetic spectrometer has allowed studies of nucleon transfer, scattering, and charge exchange reactions throughout the periodic table. More experiments have been run with solid state counters this year than has been the case recently, as a broad range spectra of the l… more

Numerical Calculation of the Three Dimensional Electrical Field in the Central Region of a Cyclotron

Description: To provide detailed and accurate electric fields in the ion source-puller region and at the dee dummy-dee gap for a cyclotron, a relaxation method solution of Laplace's equation has been used. A conventional difference equation with variation in mesh size and relaxation factor as well as different schemes for boundary corrections have been developed to achieve roughly 1 percent accuracy for a thre-dimensional domain with 10/sup 6/ mesh points. Although the computation requires considerable comp… more

Shallow Ground Water in the Boulder-Fort Collins-Greeley Area, Front Range Urban Corridor, Colorado, 1975-77

Description: From introduction: This investigation was made as part of a comprehensive geohydrologic study of the Front Range Urban Corridor in Colorado conducted by the U.S. Geological Survey. The purpose of the study was to delineate the areal extent of the aquifer, the altitude and configuration of the water table, and the gradient and underflow in various parts of the area, in order to better understand the quality of water moving into and through the aquifer.
