Thesis Title: Plasma Wakefield Accelerators Using Multiple Elec- tron Bunches
An extract from Kallos’ Thesis Abstract:
As...plasma acceleration technologies mature, one of the main future challenges is to mono-energetically accelerate a second trailing bunch by multiplying its energy in an efficient manner...The work presented here analyzes the use of multiple electron bunch- es in order to enhance certain plasma acceleration schemes. Specifically, the acceleration of a trailing electron bunch in a high- gradient wakefield driven by a preceding bunch is demonstrated experimentally for the first time... Additionally, it is found ... that by using multiple bunches to drive the wakefields, the energy of a trailing bunch could be efficiently multiplied in a single stage, thus possibly reducing the total length of the accelerator to a more manageable scale.
Kallos performed this research at the Electrical Engineering De- partment of the University of Southern California in Los Angeles under the supervision of Thomas Katsouleas.
Presently Kallos is a researcher at Queen Mary University of Lon- don, England.
