After almost 15 years of operation, X-ray FELs are well-established light sources for addressing many problems in science. However, most FEL facilities are relatively large to reach the beam energies and geometric emittance needed to lase at higher photon energy. Furthermore, the XFEL typically serves one or a few users at a time. At Argonne

National Laboratory, we have initiated a research program to address some of these issues via the development of fundamental accelerator technologies. We report on our program to develop independent undulator arrays to allow more simultaneous users. We are developing a compact Adjustable Phase Undulator that has a compact transverse footprint and a Superconducting Undulator design with multiple undulators per cryostat. In addition, we report on a new concept for a high gradient/ultralow 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. This new high gradient concept, if confirmed, could also lead to a high gradient linac, resulting in a more compact design. 

 

I will also give a brief update on progress on the APS Upgrade, a 4th generation storage ring light source currently being installed in the APS tunnel for which commissioning is planned in early 2024.
