NSSDCA ID: 1983-116A-25
Mission Name: STS 9/Spacelab 1The experiment objectives were to use electron- and ion-beam guns (up to 10 keV), an associated wave receiver (up to 100 MHz), an electron-temperature probe, and three particle detectors (1) to study ionospheric neutralization processes by studying the stability of the electronic potential of the gun with respect to the plasma, (2) to study plasma instabilities by measuring electric (up to 100 MHz) and magnetic (200 Hz to 20 MHz) wave components, (3) to use the Shuttle motion to perform ion-bounce experiments, and (4) to monitor the secondary electron flux. The equipment consisted of an active package containing an electron gun, an ion gun, and a particle detector; and a passive package containing an electric antenna, a magnetic antenna, and two particle detectors. Loss of some data was experienced due to a gas bottle failure. As a consequence only 60% of the planned objectives were accomplished.
