Abstract
An observation of longitudinal dynamics of injected beams in a storage ring has been demonstrated at the SPring-8. The observation helps make sure no significant injection loss occurs from a viewpoint of the longitudinal acceptance. More importantly, the scheme is expected to enable us to observe non-linear longitudinal dynamics of ultra-short bunches injected from the XFEL linac; the bunches are in the future going to be transferred from the XFEL linac to the storage ring, where strong coherent synchrotron radiation and other high peak current effects will not be ignorable. Experimental results obtained by a dualscan streak camera as well as numerical simulations are presented.
