Five months after first lasing in April 2009, the Linac Coherent Light Source (LCLS) began its first round of x-ray experiments. The facility rapidly attained and surpassed its design goals in terms of spectral tuning range, peak power, energy per pulse and pulse duration. There is an ongoing effort to further expand capabilities while supporting a heavily subscribed user program. The facility continues to work toward new capabilities such as multiple-pulse operation, pulse durations in the femtosecond range, and production of >16 keV photons by means of a second-harmonic “afterburner” undulator. Future upgrades will include self-seeding and polarization control. The facility is already planning to construct a major expansion, with two new undulator sources and space for four new experiment stations.

Energy Recovery Linacs (ERLs) are proposed as drivers for hard X-ray sources because of their ability to produce electron bunches with small, flexible cross sections and short lengths at high repetition rates. The advantages of ERL lightsources will be explained, and the status of plans for such facilities will be described. In particular, Cornell University plans to build an ERL light source, and the preparatory research for its construction will be discussed. This will include the prototype injector for high current CW ultra-low emittance beams, superconducting CW technology, the transport of low emittance beams, halo formation from intrabeam scattering, the mitigation of ion effects, the suppression of instabilities, and front to end simulations. Several of these topics could become important for other modern light source projects, such as SASE FELs, HGHG FELs, and XFELOs.

NSLS-II, the new 3 GeV 3rd generation light source presently under construction at Brookhaven National Laboratory will provide ultra-bright synchrotron radiation of 10²¹ photons s^-1 mm^-2 mrad^-2 0.1% BW^-1 at 2keV and high photon flux of 10¹⁵ photons s^-1 0.1% BW^-1. The facility will support a minimum of 60 beamlines. Construction started in 2009 and commissioning is expected to be completed in 2014. This report will provide a description of the NSLS-II design and will summarize the status of the construction project.

A design study of the MAX-IV light source complex in Sweden has been completed. One of MAX-IV's main light sources, a 3 GeV storage ring, is designed to achieve a natural emittance of ~0.2 nm rad. The facility will also provide SASE-XFEL using a 3 GeV high performance linear accelerator. The speaker will discuss facility targets, the concept and accelerator design, and show some possibilities approaching two-dimensional diffraction-limited X-ray generation at MAX-IV.
