我们报道了一个通过改变UVSOR存储环上的动量压缩因子来控制束团长度的实验。通过改变色散函数来改变动量压缩因子，并将其减小到普通值的大约百分之一。根据同步辐射振荡频率估算的最短束团长度为25ps，是普通值的十分之一。在动量压缩因子极低的情况下，对二阶动量压缩因子的修正是必不可少的。给出了动量压缩因子和束团长度的测量结果。
We report on an experiment to control bunch length by means of changing the momentum compaction factor on the UVSOR storage ring. The momentum compaction factor was varied by changing the dispersion function, and reduced to be approximately one hundredth of the ordinary value. The shortest bunch length estimated from the synchrotron oscillation frequency was 25 ps, which is one tenth of the ordinary value. Correction for the second order momentum compaction factor was found to be essential for operation with the extremely low momentum compaction factor. The results of measurement of the momentum compaction factor and the bunch length are presented.
