However, most FEL facilities are relatively large to reach the beam energies and geometric emittancs needed to lase at higher photon energy. Furthermore, the XFEL can only serve one or a few users at at time. At Argonne National Laboratory, we have initiated a research program to address some of these issues. We report on our program develop independent undulator arrays to allow more simultaneous users. We are developing a compact Adjustable Phase Undulator that have a compact transverse footprint and a superconducting undulator design with multiple undulators per cryostat. In addition, we report on a new concept for an ultrolow emittance electron gun which reaches fields several times higher than existing guns. This is achieved by generating <10 nsec RF pulses similar to other two-beam accelerator concepts. PB - JACoW Publishing CP - Geneva, Switzerland ER -
