From: Isolated terawatt attosecond hard X-ray pulse generated from single current spike

Shape of current spike for (a) weak bunching, (b) maximum bunching, and (c) over-bunching. Phase space of each case is plotted in the inset. (d) Peak current (blue line) and width (red line) of a current spike with respect to the bending angle of the chicane. The black dashed lines indicate the cases shown in (a),(b) and (c).
