Switching of Microwave Radiation Storage and Output Modes in Superconducting Resonance-Cavity Compressors with an Interference Switch

Superconducting Cavities in Systems of the Resonant Microwave Pulse Compression

“…In the circuit employing the impulse mode transformation the energy was stored by the high Qfactor value mode H01 (10) and extracted by the low Q-factor value mode H11 (11).…”

“…If Q-factor value of the storage and switching cavities is of 5×10 8 level about the system is capable to form pulses of 5…10ns width with the envelope shape similar to rectangular one and the amplification could exceed 60dB -Fig. 6b [11].…”

“…Compressors with ordinary cavities have the amplification factor less than 30 dB at the output pulse duration ~10 -8 s. So compressors with superconducting cavities (SC) having the order of Q-factor 4 to 6 times as much as Q-factor of ordinary copper cavities hold considerable promise. Achievable Q-factor values of SC are 10 10 to 10 11 and stored energy densities ≥1J/l enables creation of microwave pulse sources with megawatt output power level at the power amplification factor about 70 dB and using a relatively low power feeding microwave generator.…”
