Figure 4
The right-hand plots in panels (a), (b) and (c) show streak images using time windows of 1 µs, 12 ns and 2 ns, respectively; the left-hand plots represent the spectral integrated (366–376 nm) time traces of each streak image. (d) TR-XEOL spectra of a single bunch with different beam currents. The inset of (d) reveals that the emission peak intensity of TR-XEOL increases with an increase in the beam current. |
