The EXCEDE III rocket experiment successfully produced an artificial aurora on April 27, 1990, with an injected approx. 18-A beam of approx. 2.5-keV electrons. The experiment consisted of an accelerator module and a sensor module in a mother-daughter configuration. The beam was fired along the Earth's magnetic field lines between the altitudes of approx. 62 and 115 km during the flight. A major concern prior to the flight was that the injection of such an overdense electron beam into the lower ionosphere would charge the accelerator module to a significant fraction of the beam potential. To monitor the primary electrons remote from the rocket, two X ray proportional counters were included as part of the sensor module. X ray spectra from bremsstrahlung emission yield a direct measure of the primary electron beam energy outside the plasma sheath surrounding the accelerator module. Analysis of these spectra yields a beam energy of 2.2 plus or minus 0.5 keV which indicates no substantial charging of the accelerator module for the entire time that the beam was on. We also find that the X ray intensity was modulated at the few percent level by firings of the attitude control jets.
