We demonstrate a silicon-based electron accelerator that uses laser opticalnear fields to both accelerate and confine electrons over extended distances.Two dielectric laser accelerators (DLA) designs were tested, each consisting oftwo arrays of silicon pillars pumped symmetrically by pulse front tilted (PFT)laser beams, designed for average acceleration gradients 35MeV/m and 50MeV/mrespectively. The DLA are designed to act as Alternating Phase Focusing (APF)lattices, where electrons, depending on the electron-laser interaction phase,will experience alternating longitudinal/transverse focusing/defocusing. Byincorporating fractional period drift sections that alter the synchronous phasebetween $\pm 60^\circ$ off-crest, electrons captured in the designedacceleration bucket experience half the peak gradient as average gradient whilealso experiencing strong confinement forces that enable long interactionlengths. We demonstrate APF accelerators with interaction lengths up to708$\mu$m and energy gains up to $23.7 \pm 1.07$ keV FWHM, a 25\% increase fromstarting energy, demonstrating the ability to achieve substantial energy gainswith sub-relativistic DLA.
