Figure 5
(a) An image taken by dual-axis synchroscan streak camera shows longitudinal phase oscillation. The time delay between the upper and lower bunch is 4 ns. (b) A typical spatio-temporal streak-camera image showing the transient beam-ion oscillation along the bunch train. The vertical axis is 500 ns temporal scan and horizontal axis is 6.4 mm spatial scan (time span = 25 µs). Each bunch train shows a vertical bunch profile only. One can see blow-up of the bunch size as well as the increase of oscillation amplitude along the bunch train.
