A high energy electron beam is proposed to be used for time resolved imaging measurements of hydrodynamic processes in High Energy Density Laboratory Plasma (HEDLP). Generation of a high quality sub-picosecond electron beam with present RF photocathode technologies is technologically mature and cost effective. An electron bunch train with a flexible time structure is used to penetrate a time varying high density target. By imaging the scattered electron beam, the detailed target profile and its density evolution can be accurately determined. To illustrate the concept design, an experiment is proposed based on Argonne Wakefield Accelerator (AWA) beamline. An imaging lattice design and particle tracking simulation is finished.
