RESEARCH IN THE DESIGN, DEVELOPMENT AND CONSTRUCTION OF NON-MAGNETIC SENSORS FOR MAGNETIC FIELD-CHARGED PARTICLE CORRELATION STUDIES.
Abstract
The results reported can be divided into three areas: (1) Design, construction and flight on a Javelin rocket of a 'first generation' charged particle detection system, for (a) protons with energy between 0.45 MeV and 1.7 MeV, and (b) electrons between 25 keV and 200 keV. (2) Design and construction of a magnetometer range expander. (3) Design and construction for a Niros rocket of a 'second generation' charged particle detection system for (a) protons between 0.4 and 3 MeV, (b) electrons from less than 0.5 keV to 15 keV and (c) electrons from 15 keV to 200 keV. Using the system described in (1) above, the differential spectrum of electrons with E > 25 keV and the integral intensity of protons with 0.45 MeV < E < 1.7 MeV have been measured with a rocket fired into a weak aurora at Fort Churchill, Canada. The electron spectrum was observed to become softer during the flight. A correlation apparently exists between peaks in the electron and proton intensities. Broad peaks in the particle intensity correlate with broad dips in the 'X' component of a ground based magnetometer. The magnetometer record appears to be composed of a broad and symmetrical 'slow' component, and a narrow 'fast' component occuring near the start of the slower component. The measured electron spectra indicate that the 'fast' component was a hard electron precipitation while the 'slow' component resulted from a soft electron precipitation. Measurements with a 30 MHz riometer correlate well with the magnetometer record. (Author)
