Research on the Physics of Ultra-High Brightness, Ultra-Relativistic ElectronBeams

摘要

The research supported by this grant has been focused on the physics relevant tothe construction and use of state of the art high current, high brightness, ultra-relativistic electron beams in the energy range from 0.25 GeV to 1.1 GeV, namely, the 1 GeV Duke storage ring system. During this period, the Duke storage ring was commissioned and used for: production of coherent Uv radiation (from the OKA XUV EEL); production 0 spontaneous X-ray radiation: and production of a monochromatic gamma ray beam. A number of very successful theoretical results have been developed and tested. Most objectives specified in the proposal have been achieved. A number of initial objectives for the Duke storage ring have been exceeded during the commissioning of the storage ring and its subsystems. This research has led to the creation of a unique facility capable of producing high brightness electron beams with parameters exceeding initial design goals. These beams have been utilized for ground breaking achievements with the OKA FEL system, including the first and only UV FEL in the US and the first and only monochromatic gamma ray beam with tunable energy.
