LBNL is developing design concepts for a multi-beamline soft x-ray FEL array powered by a superconducting linear accelerator, operating with a high bunch repetition rate of approximately one Megahertz. The CW superconducting linear accelerator is supplied by an injector based on a high-brightness, high-repetition-rate photocathode electron gun, prototyped in the APEX experiment under way at LBNL. Electron bunches are distributed from the linac to the array of independently configurable FEL beamlines with nominal bunch rates up to 100 kHz in each FEL, and with even pulse spacing. Individual FELs may be configured for different modes of operation, including self-seeded and external-laser-seeded, and each may produce high peak and average brightness x-rays with a flexible pulse format, and with pulse durations ranging from sub-femtoseconds to hundreds of femtoseconds. This talk will describe the design concept, recent developments in the design options and performance parameters, and progress in R&D activities.
