In this paper we present a design report on a 1-1/2 cell, L Band RF photocathode gun that is capable of generating and accelerating electron beams with peak currents {gt}10 kA. We have performed simulation for bunch intensities in the range of 10{endash}100 nC with peak axial electrical field at the photocathode of 30{endash}100 MV/m. Unlike conventional short electron pulse generation, this design does not require magnetic pulse compression. Based on numerical simulations using SUPERFISH and PARMELA, this design will produce 20{endash}100 nC beam at 18 MeV with rms bunch length 0.6{endash}1.25 mm and normalized transverse emittance 30{endash}108 mm mrad. Applications of this beam for wakefield acceleration is also discussed. {copyright} {ital 1999 American Institute of Physics.}
