Nanomaterials Based Nanoplasmonic Accelerators and Light-Sources Driven by Particle-Beams

Abstract

Unprecedented tens of TVm−1 fields are modeled to be realizable using novel nanoplasmonic surface crunch-in modes in nanomaterials. These relativistic nonlinear surface modes are accessible due to advances in nanofabrication and quasi-solid density sub-micron particle bunch compression. Proof of principle of TVm−1 plasmonics is provided using three-dimensional computational and analytical modeling of GeV scale energy gain in sub-millimeter long tubes having nanomaterial walls with controllable free-electron densities, $n_{\mathrm t}\sim 10^{22-24}\mathrm {cm^{-3}}$ and hundreds of nanometer core radius driven by quasi-solid electron beams, $n_{\mathrm b}\sim 0.01n_{\mathrm t}$ . Besides the tens of TeVm−1 acceleration gradients, equally strong transverse fields lead to self-focusing and nanomodulation of the beam which drive extreme beam compression to ultra-solid peak densities increasing the crunch-in field strength. Apart from ultra-solid particle beams, extreme focusing also opens up a nano-wiggler like tunable coherent $\mathrm {\mathcal {O}(100MeV)}$ ultra-dense photon source.
