APEX the Advanced Photo-injector EXperiment at LBNL is devoted to the development of a MHz-class repetition rate high-brightness electron injector for X-ray FELs. APEX is based on a novel room-temperature 186 MHz RF gun operating in CW mode in conjunction with high quantum efficiency photocathodes capable of the required repetition rates with commercial lasers. APEX is organized in 3 phases. Phase 0 includes the demonstration of several important milestones for the project. The gun must be conditioned at full RF power in CW mode; the vacuum performance, directly impacting the lifetime of photocathodes, needs to be characterized; and different photocathodes will be tested at full repetition rate at the nominal gun energy of 750 keV. In Phase I, a new suite of beam diagnostics will be added to characterize the electron beam at the gun energy and at full repetition rate. In Phase II, a pulsed linac will be added for accelerating the beam at ~30 MeV to reduce space charge effects and measure the brightness performance of the gun when integrated in an injector scheme. Phase 0 is presently under commissioning and the first experimental results from this phase are presented.
