Abstract
Ultrafast lasers are able to generate THz pulses with >1MV/m field strengths, and with controllable electric field temporal profiles. We report progress on an experimentto demonstrate the use of laser generated THz pulses to manipulate the γ-z correlation of a ∼20MeV electron bunch on a sub picosecond time scale. The manipulation is achieved in free space, without external magnetic fieldsor undulators, by the interaction of the bunch with the longitudinal electric field of a co-propagating THz pulse in a TEM∗10-like mode. We discuss the potential for arbitrary phase space control, including the possibility of correcting temporal jitter and driving electron beams into synchronisation with the laser.
