Abstract

Dielectric laser accelerators (DLAs) have proven to be good candidates
for miniaturized particle accelerators. They rely on micro-fabricated
dielectrics which are able to modulate the kinetic energy of the
incoming electron beam under a proper laser illumination. In this paper
we demonstrate a dual pillar structure with a distributed Bragg
reflector to mimic a double sided illumination to the electron path. The
structure is fabricated by an electron beam lithography technique
followed by a cryogenic reactive ion etching process. Such a structure
can accelerate the injected 28 keV electrons by a gradient of
approximately 150 MeV/m which can be further optimized towards the GeV/m
regime.
