摘要

只提供摘要形式。本文介绍了一种用于动态核极化实验的140 GHz、100 W连续波回旋速调管放大器的初步设计和仿真结果。该放大器工作在10kv, 100ma的电子束下，仿真结果表明，在/spl alpha/=1.4时，TE/sub 02/模式的饱和增益为32db，效率为9%，输出功率为86 W。利用光子带隙(PBG)腔抑制模式竞争也在评估中。

Design of a 140 GHz, 100 W gyroklystron amplifier

Summary form only given. We present the preliminary design and the simulation results for a 140 GHz, 100 W CW gyroklystron amplifier for use in dynamic nuclear polarization (DNP) experiments. The amplifier operates with a 10 kV, 100 mA electron beam and simulations show a saturated gain of 32 dB at /spl alpha/=1.4 for the TE/sub 02/ mode with an efficiency of 9% and output power of 86 W. The use of photonic band gap (PBG) cavities to suppress mode competition is also under evaluation.
