We report on the initial characterization of the new short bunch, high intensity electron gun at the Argonne Wakefield Accelerator. The RF properties of the gun and the initial beam measurements are presented. The 1-1/2 cell L-band photocathode RF gun is expected to produce 10 - 100 nC bunches with 2 - 5 ps rms pulse length and normalized emittance less than 100 mm mrad. The beam energy at the exit of the gun cavity will be in the range 7.5 - 10 MeV. A standing-wave linac structure operating at the same frequency (1.3 GHz) will increase the beam energy to about 15 MeV. This beam will be used in wakefield acceleration experiments with dielectric loaded structures. These travelling-wave dielectric loaded structures, operating at 7.8 and 15.6 GHz, will be excited by the propagation of single bunches or by trains of up to 32 electron bunches.
