Outline of Research at the Start

The first single-shot measurement of the 3D charge density distribution of the electron bunches from laser wakefield acceleration will be conducted by using a newly designed “TR-EO” technique. The electron transverse and longitudinal profile will be reconstructed from OTR image and EO sampling, simultaneously. This research will have broad impact to studies of accelerator and THz optics.
