目前,圆聚焦型铯束管是较有发展前途的器件,因此解决如何能有效地形成用于这种管子的环形束是有意义的。 为了形成环形束,铯炉准直器往往采用蜂房型和单孔道型的。由这些准直器射出的铯原子通过圆形挡片后进入A磁铁的数量只占总发射量的很小部分,而大量的处于束中心的铯原子与挡片弹性碰撞后,又会干扰正常的铯束,使之发生散射。这样,就得不到较高的束强。 At present, the round focusing type cesium beam tube is a more promising device, so it is meaningful to solve how to effectively form a circular beam for such a tube. In order to form a toroidal beam, the cesium furnace collimator often adopts a honeycomb type and a single channel type. The cesium atoms emitted by these collimators pass through the circular blanks and then enter the A magnet, which accounts for only a small part of the total emission. However, a large number of cesium atoms in the center of the beam collide with the baffles elastically and then interfere with normal Cesium beam, so that the scattering occurs. In this way, you can not get a higher beam strength.
