National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Development of a Sub-Picosecond Tunable X-Ray Source at the LLNL Electron Linac.

DE200515013361

Publication Date	2001
Personal Author	Slaughter, D.; Springer, P.; Le Sage, G.; Crane, J.
Page Count	14
Abstract	The use of ultra fast laserpulses to generate very high brightness, ultra short (Js to ps) pulses of x-rays is a topic of great interest to the x-ray user community. In principle, femtosecond-scale pump-probe experiments can be used to temporally resolve structural dynamics of materials on the time scale of atomic motion. The development of sub-ps x-ray pulses will make possible a wide range of materials and plasma physics studies with unprecedented time resolution. A current project at LLNL will provide such a novel x-ray source based on Thomson scattering of high power, short laserpulses with a high peak brightness, relativistic electron bunch. The system is based on a mm-mrad normalized emittance photoinjector, a 100 MeV electron RF linac, and a 300 ti, 35 fs solid-state laser system. The Thomson x-ray source produces ultra fast pulses with x-ray energies capable of probing into high-Z metals, and a high flux per pulse enabling single shot experiments. The system will also operate at a high repetition rate (- 10 Hz).
