Using rf pulse compression it will be possible to boost a 50-100 MW output, expected from high power microwave tubes operating in the 10- 20 GHz frequency range, to the 300-600 MW level required by the next generation of high gradient linear colliders. Experiments have been performed at Stanford Linear Accelerator Center to test, at low power, a two-stage binary energy compressor (BEC) operating at 11.424 GHz. Using over-moded delay lines and 3 dB hybrid couplers, a 312 ns pulse was compressed to 78 ns, giving a power multiplication ratio of /approximately/3.2, and a power efficiency of 81%. Individual component insertion losses were measured to be in the range of 0.6% to 8.5%. Over-all efficiency calculated using these values agreed with measured values to /approximately/1.4%. Using best values of the measured component insertion losses, the efficiency of a proposed high power test of a three-stage BEC is estimated to be 71%, with a power multiplication of /approximately/5.7. 7 refs., 7 figs., 5 tabs.
