SN1979C - A Case Study of a Type II Radio Supernova
Since initial discovery in April 1979, the supernova SN1979C has been an object of intensive study in the radio range (Weiler et al 1981, 1982, 1983, 1986) and at other frequencies (Panagia et al 1980). From its initial ...
Experimental Investigation of Two-Electron Processes in Ion-Atom Collisions
This paper will cover two separate mechanisms currently being investigated in collisional atomic physics. The first mechanism, which is the main focus of this paper, is a double electron process investigated for the ...
Determination of Detection Efficiencies of CsI Photodiode and Microchannel Plate Detectors
We have measured the detection efficiencies of a CsI photodiode (Si02 windowed) and a microchannel plate detector (MCP) with an opaque CsI photocathode at 1850 A. Also, a detection efficiency curve was measured for a ...
Comparison of Noise Levels for Water Vapor Radiometers and the Troposphere
The Jet Propulsion Lab (JPL) has been appointed as NASA's division for unmanned space flight. Research in Very Long Baseline Interferometry (VLBI) is one aspect important to JPL. One of the largest error sources for ...
