Title: Thomson scattering in the Jefferson Lab infrared FEL (appears as a Book Chapter in Femtosecond Beam Science, edited by Mitsuru Uesaka, 2005, Imperial College Press, pp 193-201)

Abstract

As is evident elsewhere in this book, several groups have demonstrated the use of Thomson scattering of short pulses of laser photons off electrons to produce sub-picosecond X-ray bunches. Though these experiments generate short enough X-ray pulses, more work is needed to improve the resulting X-ray fluxes for routine use in femtosecond science. Prior to the construction of Jefferson Lab's high average power infrared free electron laser (FEL), Krafft predicted [Krafft (1997)] high flux X-rays from intracavity Thomson scattering of infrared light off the electron beam used to generate the infrared light. After the FEL was commissioned, a simple experiment demonstrated the existence of the X-rays at significantly higher fluxes and brightness than previous Thomson experiments. A related experiment showed the X-ray bunches to be sub-picosecond in length. In this section, they present the concepts of intra-cavity Thomson scattering and initial experiments, and they give an overview of the near future program based on the Upgrade FEL (completion in 2003) that is ten times more powerful than the initial machine.
