Multi-GeV Wakefield Acceleration in a Plasma-Modulated Plasma Accelerator
Johannes J. van de Wetering, Simon M. Hooker, Roman Walczak
We investigate the accelerator stage of a Plasma-Modulated Plasma Accelerator (P-MoPA) [Phys. Rev. Lett. 127, 184801 (2021)] using both the paraxial wave equation and particle-in-c…
Resonant excitation of plasma waves in a plasma channel
Aimee J. Ross, James Chappell, Johannes J. van de Wetering +14
We demonstrate resonant excitation of a plasma wave by a train of short laser pulses guided in a pre-formed plasma channel, for parameters relevant to a plasma-modulated plasma acc…
Stability of the Modulator in a Plasma-Modulated Plasma Accelerator
Johannes J. van de Wetering, Simon M. Hooker, Roman Walczak
We explore the regime of operation of the modulator stage of a recently proposed laser-plasma accelerator scheme [Phys. Rev. Lett. 127, 184801 (2021)], dubbed the Plasma-Modulated…
Spatial Mapping of Local Density Variations in Two-dimensional Electron Systems Using Scanning Photoluminescence
Yoon Jang Chung, Kirk W. Baldwin, Kenneth W. West +4
We have developed a scanning photoluminescence technique that can directly map out the local two-dimensional electron density with a relative accuracy of cm$^{-…
