摘要

The production of electron beam of high brightness and low emittance is critical for a variety of scientific and technological applications such as high power vacuum coherent radiation source such as microwave sources, free electron lasers (FEL) and electron imaging system. The focus is to have a robust cathode using field emission mechanism based on the process of electron tunneling from a metal's surface, which is also known as Fowler Nordheim (FN) law. When a laser is used to excite the electron emission, the mechanism is known as the Fowler- Dubridge (FD) model. In this project, we aim to improve the basic of fundamental understandings of the electron emission process (related to FN and FD models) by developing multi-dimensional (2D or 3D) models.
