Basic Studies on Auto-Resonant Peniotron Oscillator.

对于微波和亚毫米波的产生，质子加速器具有非常高的转换效率。特别是在自谐振型加速器振荡器（ARPO）中，理论上期望在该范围内的效率接近100%。本项目通过实验研究了该管的这一有前途的特性，并明确了arpo1的高效率。自共振质子加速器相互作用射频电路的设计。我们提出了磁控管型和四极型电路来维持自谐振条件，并表明这两种电路都有助于研究arpo2的高效运行。试管的设计与制造。我们设计并制作了两种用于ARPO实验的试管，其中分别安装了磁控管式和四极式腔体。实验结果及讨论。在具有磁控管型腔的试管中，正向和反向模式操作的电子效率分别为72%和50%。这些数值在回旋快波管中是最高的，显示出APO的高效运行。四极管具有宽带频率可调性，这是大功率、高效率微波和毫米波管的重要特性之一。

The peniotron is well known to have a very high conversion efficiency for generation of microwave and submillimeter wave. Especially, in an auto-resonant peniotron oscillator (ARPO), nearly 100% of the efficiency has been theoretically expected in the ranges. This project has been performed to investigate experimentally such a promising features of the tube and has cleared the high efficiency of ARPO.1. Proposal of rf circuits for the auto-resonant peniotron interaction.We proposed magnetron type and a quadrupole type circuits to sustain the autoresonant condition and showed that both circuits are useful for the investigation of high efficiency operation of ARPO.2. Design and fabrication of test tube.We designed and fabricated two types of test tube for ARPO experiments in which the magnetron type and the quadrupole type cavities are mounted respectively.3. Experimental results and discussions.A test tube with the magnetron type cavity showed the highest electronic efficiencies of 72% and 50% for forward and backward mode operations respectively. These Values are the highest in the cyclotron fast wave tubes and show clearly the highly efficient operation of APO. The quadrupole test tubed demonstrated the wide band frequency tunability which was one of the most important features in a high power and high efficiency microwave and millimeter wave tube.
