We have successfully designed, fabricated, installed, and tested a super compact X-band SLAC Energy Doubler system at SLAC. It is composed of an elegant 3 dB coupler-mode converter-polarizer coupled to a single spherical energy storage cavity with high Q(0) of 94000 and a diameter less than 12 cm. The available rf peak power of 50 MW can be compressed to a peak average power of more than 200 MW in order to double the kick for the electron bunches in a rf transverse deflector system and greatly improve the measurement resolution of both the electron bunches and the x-ray free-electron laser pulses. The design physics and fabrication as well as the measurement results will be presented in detail. High-power operation has demonstrated the excellent performance of this rf compression system without rf breakdown, sign of pulse heating, and rf radiation.
