A ROCKET BORNE AIR DENSITY MEASUREMENT SYSTEM UTILIZING ELECTRON-BREMSSTRAHLUNG-CALIBRATION AND FLIGHT,
Abstract
Calibration and Flight of rocket systems for density measurement in the 100 - 200 km region is described. This system utilizes detection of bremsstrahlung x-rays generated by injection of an electron beam from the rocket into the atmosphere. At the high altitudes for which this system is designed the detected x-ray flux is linearly related to the ambient air density. Data on calibration of two payloads is given, and an analysis is made of results obtained when one of these was flown. Due to the fact that the electron beam current ceased almost immediately after the guns were opened, no air density information was obtained. A useful altitude profile of x-ray background was measured. Conclusions are given with regard to probable causes for lack of beam current, and with regard to the calibrations obtained. Recommendations related to further flights are presented. (Author)
