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.
