Single Event Effects in Aerospace by Edward Petersen

By Edward Petersen

This publication introduces the elemental innovations essential to comprehend unmarried occasion phenomena which can reason random functionality blunders and catastrophic mess ups to electronics units. As miniaturization of electronics elements advances, electronics elements are extra weak within the radiation setting. The ebook features a dialogue of the radiation environments in area and within the surroundings, radiation cost prediction counting on the orbit to permit electronics engineers to layout and choose radiation tolerant elements and structures, and unmarried occasion prediction.Content:

2 The Magnetosphere, Cosmic Ray, and Trapped Particle Motion The Earth’s magnetosphere consists of both an external and an internal magnetic field. The external field is the result of the solar wind. The internal or geomagnetic field originates primarily from within the Earth and is approximately a dipole field. Figure 2-8 shows how the solar wind and its imbedded magnetic field tend to compress the geomagnetic field. The solar wind generally flows around the geomagnetic field. Figure 2-9 shows the geomagnetic field, which is approximately dipolar for altitudes of up to about 4 or 5 Earth radii.

The heavy nuclei are the dominant source of single event upsets down to roughly 85,000 ft and should be considered down to 60,000 ft [Tsao 1984, Hands 2009]. Figure 2-53 shows the attenuation of the cosmic rays as they enter the atmosphere. The heavy ions with large cross sections are rapidly attenuated. Figure 2-54 shows how the number of heavy ions varies with altitude and cutoff rigidity. The top of the atmosphere is at approximately 150,000 feet. Figure 2-55 shows the general nature of cosmic ray showers.
