Figure 7
Dependence of the pulse width of the optical klystron radiation on the storage-ring electron bunch current. Δ was read in the range 12100–12400 Hz according to the long-term drift. The solid line shows a least-squares fit (14.5 ps mA−1) for the slope. The pulse width measured by a picosecond streak camera in a relatively higher bunch-current region is shown in the inset for reference. |
