An optically pumped cesium beam resonator has been designed including three successive magnetic field regions. The optical interactions take place in the first and third regions, where the magnetic field has the required value of 3x10(-5) T. The microwave interaction occurs in the intermediate region, where the value of the C-field is typically set to 4x10(-6) T. It has been verified that the magnetic field profile along the cesium beam does not induce Majorana transitions. Using a single laser diode emitting at 852 nm with a linewidth of about 30 MHz, the resonator gives an excellent amplitude signal to noise ratio equal to 20000 in a 1-Hz bandwidth.
已设计出一种光泵铯束谐振器，它包括三个连续的磁场区域。光学相互作用发生在第一和第三区域，其中磁场具有所需的3×10⁻⁵ T值。微波相互作用发生在中间区域，其中C场的值通常设定为4×10⁻⁶ T。已经证实，沿铯束的磁场分布不会引发马约拉纳跃迁。该谐振器使用一个发射波长为852 nm、线宽约为30 MHz的单激光二极管，在1 Hz带宽内给出了高达20000的出色幅度信噪比。
