AbstractA cosmic ray magnetic particle spectrometer utilizing wire spark chambers and a superconducting magnet for momentum determination and scintillators for charge and velocity determination has been operated on top of Mt. Lemmon near Tucson, Arizona at an atmospheric depth of 747 g/cm². Twenty weeks of data were taken and the proton energy spectrum in the momentum range of 0.6 to 2.4 GeV/c has been determined. Antiproton events were observed and a p/p ratio of 1.5(+1.85,-0.95) x 10⁻³ at a momentum of 1.05 GeV/c was measured. Deuteron intensities and alpha particle upper limits for this energy region are also presented.

Quantifying Mesoscale Soil Moisture with the Cosmic-Ray RoverChrisman, Bobby Brady (The University of Arizona., 2013)Existing techniques measure soil moisture either at a point or over a large area many kilometers across. To bridge these two scales, we used the mobile cosmic-ray probe, or cosmic-ray rover, an instrument similar to the recently developed COSMOS probe, but bigger and mobile. This study explores the challenges and opportunities for making maps of soil moisture over large areas using the cosmic-ray rover. In 2012, soil moisture was mapped 22 times in a 25 km x 40 km survey area of the Tucson Basin at 1 km² resolution, i.e., at a scale comparable to that of a pixel for the Soil Moisture and Ocean Salinity (SMOS) satellite mission. The soil moisture distribution is influenced mainly by climatic variations, notably by the North American monsoon, which resulted in a systematic change in the regional variance as a function of the mean soil moisture.
SPECTROSCOPY FROM THE HUBBLE SPACE TELESCOPE COSMIC ORIGINS SPECTROGRAPH OF THE SOUTHERN NOVA-LIKE BB DORADUS IN AN INTERMEDIATE STATEGodon, Patrick; Sion, Edward M.; Gänsicke, Boris T.; Hubeny, Ivan; de Martino, Domitilla; Pala, Anna F.; Rodríguez-Gil, Pablo; Szkody, Paula; Toloza, Odette; Univ Arizona, Steward Observ (IOP PUBLISHING LTD, 2016-12-13)We present a spectral analysis of the spectrum from the Hubble Space Telescope Cosmic Origins Spectrograph (HST/COS) of the southern VY Scl nova-like variable BB Doradus, obtained as part of a Cycle 20 HST/COS survey of accreting white dwarfs (WDs) in cataclysmic variables. BB Dor was observed with COS during an intermediate state with a low mass accretion rate, thereby allowing an estimate of the WD temperature. The results of our spectral analysis show that the WD is a significant far-ultraviolet (FUV) component of the spectrum with a temperature of about 35,000-50,000 K, assuming a WD mass of 0.80 M-circle dot (log(g) = 8.4). The disk, with a mass accretion rate of approximate to 10(-10) M-circle dot yr(-1), contributes about 1/5 to 1/2 of the FUV flux.
