Positron Acceleration in an Elongated Bubble Regime
Tianhong Wang, Vladimir Khudik, Gennady Shvets
A new concept is proposed for accelerating positrons in a nonlinear plasma wakefield accelerator. By loading the wakefield (back of the plasma bubble) with a short electron bunch,…
Sub-femtosecond wakefield injector and accelerator based on an undulating plasma bubble controlled by a laser phase
Jihoon Kim, Tianhong Wang, Vladimir Khudik +1
We demonstrate that a long-propagating plasma bubble executing undulatory motion can be produced in the wake of two co-propagating laser pulses: a near-single-cycle injector and a…
Electron energization in upstream of collisionless electron/ion shocks produced by interpenetrating plasmas
Neda Naseri, Vladimir Khudik, Gennady Shvets
We discuss the mechanism of electron energization in the upstream region of relativistic e/i shock. By using particle-in-cell simulations, we demonstrate the electrons interacting…
Laser-Pulse and Electron-Bunch Plasma Wakefield Accelerator
Tianhong Wang, Vladimir Khudik, Gennady Shvets
Propagation distances of intense laser pulses and high-charge electron beams through the plasma are, respectively, limited by diffraction and self-deceleration. This imposes severe…
Laser-Ion Lens and Accelerator
Tianhong Wang, Vladimir Khudik, Gennady Shvets
Generation of highly collimated monoenergetic relativistic ion beams is one of the most challenging and promising areas in ultra-intense laser-matter interactions because of the nu…
Direct laser acceleration of electrons by tightly focused laser pulses
Tianhong Wang, Vladimir Khudik, Alexey Arefiev +1
We present an analytical theory that reveals the importance of the longitudinal laser electric field in the resonant acceleration of relativistic electrons by the tightly confined…
