Status of high power technology for educational satellites
A 1971 NASA technical report by P. W. Kuhns on high-power transmitter technology for educational broadcast satellites, issued for engineers through the agency's report series. The two figures are line drawings: a labelled cutaway of a klystron-type tube with dashed electron trajectories and battery symbols, and a hatched perspective view of a satellite with a ribbed 9-meter dish and solar panels.
