自1968年提出新二极束光学的设想以来,先后曾在Cs-Ⅰ和Cs-Ⅲ两台装置上进行过四次实验。对此种束光学的原理及所获得的较好的实验结果,都已作过报导。另外刘海峰同志在这方面也进行过一些较成功的实验。但是这些实验中的大部分,其磁铁都采用磁场梯度与磁场平行的结构,只有一次实验是采用磁场梯度与磁场垂直的结构,而从实验结果来看,后者的性能更好,且其梯度的分布也更易于控制。为了进一步考查后一种结构的性能及
Since the assumption of new diode beam optics in 1968, four experiments have been conducted on two Cs-Ⅰ and Cs-Ⅲ devices. The principle of such beam optics and the better experimental results obtained have been reported. In addition, Comrade Liu Haifeng also conducted some more successful experiments in this regard. However, in most of these experiments, the structure of magnetic field gradient parallel to the magnetic field was adopted for the magnets. Only one experiment was conducted using a structure in which the magnetic field gradient was perpendicular to the magnetic field. From the experimental results, the latter showed better performance and the gradient The distribution is also easier to control. In order to further examine the performance of the latter structure and
