Laser-Driven Acceleration In Clustered Plasmas
(2009-01)
We propose a new approach to avoid dephasing limitation of laser wakefield acceleration by manipulating the group velocity of the driving pulse using clustered plasmas. We demonstrated the control of phase velocity in ...
Magnetized Plasma-Filled Waveguide: A New High-Gradient Accelerating Structure
(2009-01)
Electromagnetic waves confined between the metal plates of a plasma-filled waveguide are investigated. It is demonstrated that when the plasma is magnetized along the metallic plates., there exists a luminous accelerating ...
Attraction And Repulsion Of Multi-Color Laser Beams In Plasmas: A Computational Study
(2009-01)
The nonlinear interaction of high-power multi-color laser beams in plasmas is investigated numerically. Both the relativistic mass increase and the driven plasma wave contribute to the mutual beam-beam interaction and to ...
Modeling Asymmetric Beams Using Higher-Order Phase-Space Moments
(2012-06)
Shadwick et al. developed [Commun. Nonlinear. Sci. Numer. Simulat. 17, 2153-2160 (2012)] a self-consistent model of beam transport using a phase-space moment description (up to 2nd order) based on the Vlasov-Maxwell ...
Summary Report Of Working Group 8: Laser Technology For Laser-Plasma Accelerators
(2012-06)
Laser Technology has long been the limiting and the enabling step for laser plasma accelerators. The work presented here addressed the current and near future laser technology relevant to particle acceleration as well as ...
Emittance Control In Laser Wakefield Accelerator
(2001-05)
In this paper we summarize our recent effort and results in theoretical study of the emittance issues of multistaged Laser Wakefield Accelerator (LWFA) in TeV energy range, In such an energy regime the luminosity and ...
Optimization Of Laser Wakefield Acceleration
(2001)
Using an evolutionary strategy algorithm, we optimize the generalized transformer ration of a laser wakefield accelerator. The algorithm tests several realistic pulse shapes by integrating the fluid wakefield differential ...
Preparation For Laser Wakefield Experiments Driven By The Texas Petawatt Laser System
(2009)
Laboratories around the world are planning petawatt laser driven experiments. The Texas petawatt laser offers the ability to demonstrate laser wake field acceleration (LWFA) in a unique regime with pulse duration (similar ...
Two-Color Terawatt Laser System For High-Intensity Laser-Plasma Experiments
(2012-06)
We report a two-color terawatt laser system for use in controlling laser-plasma instabilities. The system includes a commercial 45 TW Ti:Sapphire laser system at 800 nm, temporally synchronized with a 1 TW CPA Raman-Ti:Sapphire ...
Single-Shot Visualization Of Evolving Laser- Or Beam-Driven Plasma Wakefield Accelerators
(2012-06)
We introduce Frequency-Domain Tomography (FDT) for visualizing sub-ps evolution of light-speed refractive index structures in a single shot. As a prototype demonstration, we produce single-shot tomographic movies of ...
