چکیده
LLE Review, Volume 118 68 Laser-generated relativistic electron beams have applications in compact, high-brightness laser–plasma particle accelerators,1 narrowband x-ray sources for medical applications,2 x-ray sources for ignition-scale, high-density inertial confinement fusion (ICF) target backlighter radiography,3 collimated electron beams for free-electron lasers,4 and collimated electron beams for the fast-ignition approach to ICF.5 The fast electrons are generated by focusing short-pulse, high-intensity, I + 1019 W/cm2 laser light onto the front surface of planar-foil targets.6 An understanding of the fast-electron generation and subsequent transport is essential for these applications.

Sub-picosecond electron bunch length measurement by terahertz radiation S.Zhang S.Benson D.Douglas M.Shinn and G.Williams
This paper presents the measurement of sub-picosecond relativistic electron beam bunch length by analyzing the spectra of the coherent terahertz pulses through Kramers-Kronig transformation. The results are compared with autocorrelation from a scanning polarization autocorrelator that measures the coherent optical transition radiation. The limitations of the different methods to such a characte...
متن کاملSingle-shot coherent diffraction imaging of microbunched relativistic electron beams for free-electron laser applications.
With the advent of coherent x rays provided by the x-ray free-electron laser (FEL), strong interest has been kindled in sophisticated diffraction imaging techniques. In this Letter, we exploit such techniques for the diagnosis of the density distribution of the intense electron beams typically utilized in an x-ray FEL itself. We have implemented this method by analyzing the far-field coherent t...
متن کاملFast-Electron Source Characterization and Transport in High-Intensity Laser-Solid Interactions and the Role of Resistive Magnetic Fields
An electron transport regime is identified in which >1 MA, relativistic currents, generated by high-intensity, laser-target interactions, are collimated (or focused) by self-generated, resistive, magnetic fields within solid-density targets. The strongest magnetic fields appear at the edge of the electric current due to the radial shear in the current density. High-resolution coherent transitio...
متن کاملBelow gap optical absorption in GaAs driven by intense, single-cycle coherent transition radiation.
Single-cycle terahertz fields generated by coherent transition radiation from a relativistic electron beam are used to study the high field optical response of single crystal GaAs. Large amplitude changes in the sub-band-gap optical absorption are induced and probed dynamically by measuring the absorption of a broad-band optical beam generated by transition radiation from the same electron bunc...

The generation of coherent Terahertz (THz) radiation is studied which is produced from moving the relativistic electron beam through a helical wiggler with axial magnetic field. The relativistic electron beam is modulated via interacts with the beat wave of two laser beams that have frequency difference in THz range. When the modulated relativistic beam of electrons go through the helical wiggl...
