dc.description.abstractIn this thesis, experimental studies are presented on longitudinal space-charge wave dynamics in space-charge dominated beams. Space-charge wave equations are derived using a cold-fluid model. Two kinds of perturbation are examined: an initial single peak pure-density perturbation and a small sinusoidal density modulation. The theoretical evolution of these two kinds of perturbation is compared with WARP RZ simulations. A new experimental method using a laser to produce such an initial pure-density perturbation is studied. The propagation of the resulting space-charge waves in University of Maryland Electron Ring (UMER) is measured and analyzed for different combinations of main beam current and perturbation current. Good agreement is achieved in all the theoretical analyses, simulation results and experimental measurements. In addition to the longitudinal space-charge wave dynamics study, the reconstruction of the transverse phase space of the photoemission beam is also reported.en_US
