	Funding: Parts of this work were performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344. The use of electromagnetic structures to couple energy to a charged particle beam is well known. These structures are usually driven by an external source of electromagnetic energy and the structure distributes that energy is such a way as being favorable to accelerate charged particles. Photonic crystals typically consist of periodic arrays of metal and/or dielectric structures spaced on a scale comparable to the wavelength of interest, have been investigated for use both as sources of microwave radiation and particle accelerators. In this case we consider driving a photonic crystal structure using a repetitive sequence of charge bunches driven from a photo-injector to resonantly excite the structure to produce an acceleration field to accelerate a suitably-delayed witness charge bunch to high energy. We examine the generation of the acceleration field as well as spurious modes. The dynamics of the witness bunch are examined to determine the longitudinal dynamics of the bunch and the energy spectra.
