Description

同轴谐振腔双电子注回旋管
技术领域：
本发明与大功率毫米波器件有关，尤其与同轴回旋管有关。
背景技术：
能源危机是世界各国面对的重大问题，新型能源的探索与开发受到各国政府和科学家的高度重视。受控热核反应为新能源的产生提供了最重要的途径，耗资数千亿美元的国际ITER计划将高密度等离子体加温到上亿度的高温，从而实现受控核聚变，将给人类带来丰富的净洁的能源。实现这一计划的关健之一就在于等离子体加热。回旋管被用于ITER等离子加热，提高回旋管的输出功率是ITER计划成功的关键。为此科学家提出了同轴回旋管，同轴回旋管由同轴谐振腔和单注电子注构成，电子枪产生的一个环形回旋电子注在电磁场作用下产生高的微波功率从微波输出窗输出，同轴回旋管除用于加热等离子外还可用于毫米波雷达系统和高性能精密陶瓷的烧结。目前回旋管的研究受到国际科学界的高度重视，正努力提高工作频率，输出功率和效率。
发明的内容：
本发明的目的是提供一种输出功率高，互作用状态调整灵活，互作用效率高的同轴谐振腔双电子注回旋管。
本发明是这样实现的：
本发明同轴谐振腔双电子注回旋管，由电子枪、同轴谐振腔和磁性管构成，同轴谐振腔由同轴的外导体1和内导体4组成，电子枪产生的两个环形电子柱2、3位于内、外导体之间并与内、外导体同轴。
同轴谐振腔置于磁性管中，磁性管的磁场形状与常规磁性管的相同或类似。
内、外导体和磁性管的横截面为圆形。
电子枪有位于阳极套5内的阴极套6，阴极套上有两个发射环7、8分别产生环形电子柱2、3。
大功率回旋管(每个输出功率希望能达到兆瓦)是受控热核反应的重要加热功率源，是最终解决人类能源问题的重大科学研究项目。我国已参加国际实验热核反应堆(ITER)计划。ITER装置一次需用24个兆瓦级的回旋管，现有的回旋管目前尚不能真正达到连续波1兆瓦。因此，本专利提出的双电子注回旋管又极重要的意义。
本发明采用两个同轴环形电子注形成一种新型的同轴谐振腔双电子注回旋管。与普通单注回旋管相比，双注回旋管具有一系列突出的优点，理论研究和模拟计算表明这种同轴谐振腔双电子注回旋管具有非常优异的表现：一，采用双电子注以后，工作电流可以大幅度提高，因而可提高微波输出功率2至4倍；二，与单注相比，两电子注都可处于实现注波互作用的最佳位置，互作用状态的调整更加灵活，互作用功率很高，可达72％的直流功率，比单注管的40％左右的互作用效率有明显提高，并可有效的改善单注回旋管中的模式竞争问题。本发明还证明同轴谐振腔双电子注回旋管可以有双频输出，及一个回旋管可以同时输入两个频率，一个是基频，另一个是倍频。这就使本发明的同轴谐振腔双电子注回旋管可以有特殊重要的应用价值。
本发明关键在于采用双电子注，在同轴回旋管中，使用两个环形电子注。我们证明此两个环形电子注的电位可以相同。我们的理论证明本发明可使同轴回旋管的输出功率大大提高，模式竞争大大改善。
附图说明：
图1为本发明双电子注同轴谐振腔结构示意图。
图2为本发明产生的电子注示意图。
图3为电子枪结构图。
具体实施方式：
本发明所提供的同轴谐振腔双电子注回旋管由图1所示的开放式同轴谐振腔外导体1，电子注2，电子注3和同轴谐振腔内导体4组成。同轴谐振腔双电子注回旋管完全置于强磁场中，磁场形状类似于常规同轴回旋管的磁场。电子注与腔中的微波场产生电子回旋谐振相互作用，电子注中电子的动能转换成为微波场能量，从而产生大功率的微波输出。
本发明的工作过程如下：由特殊电子枪产生的两个同轴环形电子注注入同轴谐振腔，同轴环形回旋电子注与腔中电磁波场相互作用。当电子回旋频率与谐振腔中某一模式的谐振频率接近时，由电子回转谐振原理，在谐振腔中激励起微波振荡，微波振荡达到饱和输出。
电子枪的锥形阳极套5内有锥形阴极套6，阴极套6上有两个发射环7、8分别发射环形电子柱2、3。内导体4位于阴极套6内，上述各元件通过绝缘体9、10连接。
