The field of dielectric laser accelerators (DLA) garnered a considerable interest in the
past six years as it offers novel opportunities in accelerator science and potentially transformative
applications. Currently, the most widespread approach considers silicon-based structures due
to their low absorption and high refractive index in the infrared spectral region and the well-
developed silicon processing technology. In this paper we investigate a diamond as an alternative
to silicon, mainly due to its considerably higher damage threshold. In particular, we find that
our diamond grating allows a three times higher acceleration gradient (60 MeV/m) compared to
silicon gratings designed for a similar electron energy. Using more complex geometries, GeV/m
acceleration gradients are within reach for subrelativistic electrons.
