A high brightness photoelectron injector must be developed as a part of the BERLinPro ERL program. The injector is designed to produce an electron beam with 100mA average current and a normalized emittance of 1mm mrad. The project is realised in stages. First experience is gained with a fully superconducting RF gun with a Pb cathode, work ongoing, followed by a normal conducting CsK2Sb cathode capable of generating high current beams. In the first stage we have measured the fundamental beam parameters bunch charge, beam energy and energy spread with a special focus on the measurement of the transverse beam profiles. We also discuss our plans for the beam characterization at high currents.
