Variations In Meteorological Elements During Three Minnesota Partial Eclipses, L. E. Newman, J. E. Ljungkull, D. G. Baker, D. L. Ruschy, J. A. Zandlo

Journal of the Minnesota Academy of Science

The University of Minnesota climatological observatory on the St. Paul campus has been in the path of four partial eclipses, ranging from 500/4 to 91 % of totality (the area of the covered sun) since operations began in 1960. Three of the four partial eclipses occurred while the atmosphere at St. Paul was essentially cloud-free. Measurements made during the three partial eclipses include incoming and reflected solar radiation, incoming and outgoing longwave radiation, air and soil temperatures, relative humidity, and wind speed and direction. Of the partial eclipses for which the effects could be measured, only the one of 30 …

Monte Carlo Simulation Of The Scintillating Optical Fiber Calorimeter (Sofcal), Zibin Yang, Russell Gillum, Donald C. Wold

Journal of the Arkansas Academy of Science

A scintillating optical fiber calorimeter (SOFCAL) is being developed by NASA/Marshall Space Flight Center for use in balloon-borne emulsion chambers to study the spectrum of high-energy cosmic rays and gamma rays. SOFCAL will not saturate for long exposures, and the detector will be helpful for the study of primary cosmic-ray nuclei energies from 100 GeV to 1,000 TeV. For a given incident particle and energy, computer simulations of electromagnetic cascades allow computation of energy deposited in different regions of the calorimeter. For these initial simulations, a 5-cm x 5-cm x 7-cm calorimeter was used. Each subsection contained a 0.4-cm thick …
