Terahertz-driven linear electron acceleration

The cost, size and availability of electron accelerators are dominated by the achievable accelerating gradient. Conventional high-brightness radio-frequency accelerating structures operate with 30-50 MeV m(-1) gradients. Electron accelerators driven with optical or infrared sources have demonstrated accelerating gradients orders of magnitude above that achievable with conventional radio-frequen...

Toward a terahertz-driven electron gun

Femtosecond electron bunches with keV energies and eV energy spread are needed by condensed matter physicists to resolve state transitions in carbon nanotubes, molecular structures, organic salts, and charge density wave materials. These semirelativistic electron sources are not only of interest for ultrafast electron diffraction, but also for electron energy-loss spectroscopy and as a seed for...

FDTD analysis of PBG waveguides, power splitters and switches

Finite two-dimensional photonic bandgap (PBG) structures were analyzed with a ®nite-difference time-domain (FDTD) full wave, vector Maxwell equation simulator. Removal of particular portions of these PBG structures lead to interesting sub-micron-sized waveguiding environments. Several waveguides and power dividers were designed and evaluated. By introducing further defects into the PBG waveguid...

Laser - Driven Electron Acceleration in Infinite Vacuum

I first review basic models for laser-plasma interaction that explain electron acceleration and beam confinement in plasma. Next, I discuss ponderomotive electron acceleration in infinite vacuum, showing that the transverse scattering angle of the accelerated electron may be kept small with a proper choice of parameters. I then analyze the direct (a.k.a. linear) acceleration of an electron in i...

Proposed Waveguide Structure for Laser Driven Electron Acceleration

Solid state lasers have achieved high energy output with very short pulses (several Joules with pulses shorter than 1ps, peak power in the order of terawatts)[1]-[5]. Lithography and micro machining enables fabrication of features much less than 1μ m[13]-[17]. Combined with the fact that material damage threshold increases with shorter pulses[20][21], it is now possible to achieve electric fiel...
