Diagnostics with Rocketborne Electron Beam Fluorescence Probes.
Abstract
An Electron Beam Fluorescence Probe (EBFP) has been developed for rocket flight applications in the 65 - 200 km altitude range. The EBFP is a non-perturbing probe which is capable of measuring vibrational and rotational temperatures as well as neutral gas species concentrations remote from the rocket payload. The spatial resolution of the probe is approximately equal to the beam diameter (1 - 2 mm). The instrument employs a 2.5 keV energy electron beam to induce fluorescence in the ambient gas. The resulting radiation is analyzed with a spectrally selective electro-optical detection system. Several versions of the EBFP were flown on Black Brant rockets from Fort Churchill, Manitoba, Canada; the results from these flights as well as the development of the instrumentation are discussed.
