Coherent synchrotron radiation by excitation of surface plasmon polariton on near-critical solid microtube surface
Bifeng Lei, Hao Zhang, Daniel Seipt +5
Coherent synchrotron radiation (CSR) is crucial for the development of powerful ultrashort light sources. We present a mechanism for generating CSR in the form of generalised super…
Leaky surface plasmon-based wakefield acceleration in nanostructured carbon nanotubes
Bifeng Lei, Hao Zhang, Cristian Bontoiu +6
Metallic carbon nanotubes (CNTs) can provide ultra-dense, homogeneous plasma capable of sustaining resonant plasma waves-known as plasmons-with ultra-high field amplitudes. These w…
Electron Acceleration in Carbon Nanotubes
Cristian Bontoiu, Alexandre Bonatto, Öznur Apsimon +16
Wakefield wavelengths associated with solid-state plasmas greatly limit the accelerating length. An alternative approach employs 2D carbon-based nanomaterials, like graphene or car…
100s TeV/m-Level Particle Accelerators Driven by High-density Electron Beams in Micro Structured Carbon Nanotube Forest Channel
Bifeng Lei, Hao Zhang, Cristian Bontoiu +5
Solid-state materials, such as carbon nanotubes (CNTs), have the potential to support ultra-high accelerating fields in the TV/m range for charged particle acceleration. In this st…
Plasmonic excitations in graphene layers
Pablo Martín-Luna, Alexandre Bonatto, Cristian Bontoiu +3
The interaction of fast charged particles with graphene layers can generate electromagnetic modes. This wake effect has been recently proposed for short-wavelength, high-gradient p…
