Phys. Rev. Lett. 100, 195001 (2008) [4 pages]Direct Acceleration of Electrons in a Corrugated Plasma WaveguideReceived 15 August 2007; published 14 May 2008 Historically, direct acceleration of charged particles by electromagnetic fields has been limited by diffraction, phase matching, and material damage thresholds. A recently developed plasma micro-optic [ B. Layer et al. Phys. Rev. Lett. 99 035001 (2007)] removes these limitations and promises to allow high-field acceleration of electrons over many centimeters using relatively small femtosecond lasers. We present simulations that show a laser pulse power of 1.9 TW should allow an acceleration gradient larger than 80 MV/cm. A modest power of only 30 GW would still allow acceleration gradients in excess of 10 MV/cm. © 2008 The American Physical Society URL:
