The BNL/SLAC/UCLA symmetrized 1.6 Cell S-band emittance-compensated photoinjector has been installed at the Brookhaven Accelerator Test Facility (ATF). The commissioning results and performance of the photocathode injector are presented. This emittance-compensated photoinjector consists of the symmetrized BNL/SLAC/UCLA 1.6 cell S-band photocathode radio-frequency (rf) gun and a single solenoidal magnet for transverse emittance compensation 1. The highest acceleration field achieved on the cathode is 150MV/m, and the normal operating field is 130MV/m. The quantum efficiency of the copper cathode was measured to be 4.5{times}10{sup {minus}5}. The transverse emittance and bunch length of the photoelectron beam were measured. The optimized rms normalized emittance for a charge of 300 pC is 0.7 {pi} mm-mrad. The bunch length dependency of photoelectron beam on the rf gun phase and acceleration fields were experimentally investigated. {copyright} {ital 1997 American Institute of Physics.}
