title: Generation of High Brightness X-Rays with the PLEIADES Thomson X-Ray Source

format: conference procceeding

conference: 2003 Particle Accelerator Conference

year: 2003

14 authors: W. J. Brown | S. Anderson | C. P. J. Barty | J. K. Crane | R. R. Cross | D. N. Fittinghoff | F. V. Hartemann | J. Kuba | G. P. Le Sage | D. R. Slaughter | P. T. Springer | A. Tremaine | J. B. Rosenzweig | D. J. Gibson

abstract: The use of short laser pulses to generate high peak intensity, ultra-short x-ray pulses enables exciting new experimental capabilities, such as femtosecond pump-probe experiments used to temporally resolve material structural dynamics on atomic time scales. PLEIADES (Picosecond Laser Electron InterAction for the Dynamic Evaluation of Structures) is a next generation Thomson scattering x-ray source being developed at Lawrence Livermore National Laboratory (LLNL). Ultra-fast picosecond x-rays (10-200 keV) are generated by colliding an energetic electron beam (20-100 MeV) with a high intensity, sub-ps, 800 nm laser pulse. The peak brightness of the source is expected to exceed 1020 photons/s/0.1 bandwidth/mm2/mrad2. Simulations of the electron beam production, transport, and final focus are presented. Electron beam measurements, including emittance and final focus spot size are also presented and compared to simulation results. Measurements of x-ray production are also reported and compared to theoretical calculations.

title: Ultrafast materials probing with the LLNL Thomson X-ray source

format: conference procceeding

conference: 2002 Linear Accelerator Conference

year: 2002

24 authors: A. Tremaine | S. Anderson | W. Brown | C. Barty | R. Cauble | J. Crane | H. Cynn | C. Ebbers | D. Fittinghoff | D. Gibson | F. Hartemann | I. Jovanovich | J. Kuba | G. P. Le Sage | A.

abstract: The use of short laser pulses to generate very high brightness, ultra short (fs to ps) x-ray pulses is a topic of great interest. 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. PLEIADES (Picosecond Laser Electron Interaction for Dynamic Evaluation of Structures), the Thomson scattering project at LLNL, will provide such a novel x-ray source of high power using short laser pulses and a high brightness, relativistic electron bunch. The system is based on a 5 mm-mrad normalized emittance photoinjector, 100 MeV electron RF linac, and a 300 mJ, 35 fs solid-state laser system. PLEIADES will produce ultra fast pulses with x-ray energies (60 keV) capable of probing into high-Z metals.

title: Experimental characterization of an ultrafast Thomson scattering x-ray source with three-dimensional time and frequency-domain analysis

format: journal article

year: 2004

18 authors: W. J. Brown | S. G. Anderson | C. P. J. Barty | S. M. Betts | R. Booth | J. K. Crane | R. R. Cross | D. N. Fittinghoff | D. J. Gibson | F. V. Hartemann | E. P. Hartouni | J. Kuba | G. P. Le Sage | D. R. Slaughter | A. M. Tremaine | A. J. Wootton | P. T. Springer | J. B. Rosenzweig

abstract: We present a detailed comparison of the measured characteristics of Thomson backscattered xrays produced at the Picosecond Laser-Electron Interaction for the Dynamic Evaluation of Structures facility at Lawrence Livermore National Laboratory to predicted results from a newly developed, fully three-dimensional time and frequency-domain code. Based on the relativistic differential cross section, this code has the capability to calculate time and space dependent spectra of the x-ray photons produced from linear Thomson scattering for both bandwidth-limited and chirped incident laser pulses. Spectral broadening of the scattered x-ray pulse resulting from the incident laser bandwidth, perpendicular wave vector components in the laser focus, and the transverse and longitudinal phase spaces of the electron beam are included. Electron beam energy, energy spread, and transverse phase space measurements of the electron beam at the interaction point are presented, and the corresponding predicted x-ray characteristics are determined. In addition, time-integrated measurements of the xrays produced from the interaction are presented and shown to agree well with the simulations.
