We describe and discuss solutions for an innovating sub-relativistic electron source, based on pulsed DC gun, including linear (1D) Field Emitter Array (FEA) associated immediately with Laser Dielectric Accelerator (DLA) stage. That setup is designed to avoid any standard accelerator component (electrostatic or magnetic macroscopic dipole ...) Parts of the diagnostics, including spectrometer and all diagnostics, are planned to rely on nano-structures. Then the entire setup -pulsed source, laser…

Design of a subnanometer resolution beam position monitor for dielectric laser accelerators.
TLDR
A new concept for a beam position monitor with the unique ability to map particle beam position to a measurable wavelength is presented, and through finite-element frequency-domain simulations, a resolution of 0.7 nm is shown.
Schottky-enabled photoemission in a rf accelerator photoinjector: possible generation of ultralow transverse thermal-emittance electron beam.
TLDR
A clear signature of the Schottky effect is presented in a rf photoinjector using photons with energy lower than the Mg cathode work function, which is a viable method to generate an electron beam with very low thermal emittance and thus, a high brightness beam.
Method for computationally efficient design of dielectric laser accelerator structures.
TLDR
Using the adjoint variable method, a highly efficient technique used to compute the sensitivity of an objective with respect to a large number of parameters, numerical optimizations aimed at maximizing acceleration gradients generate fabricable structures of greatly improved performance in comparison to previously examined geometries.
