We present the results of transverse emittance and longitudinal current profile measurements of high bunch charge (>100 pC) beams produced in the dc gun-based Cornell photoinjector. In particular, we show that the cathode thermal emittance dominates the final emittance at charges up to 300 pC. Additionally, we demonstrate excellent agreement between optimized 3D space charge simulations and measurement, and show that the quality of the transverse laser distribution limits the optimal simulated and measured emittances.
