The Linac Coherent Light Source was designed from the outset to provide options for expansion. The LCLS-II Project will implement one of these options, the addition of a new undulator tunnel, two new x-ray sources (250-2,000 eV and 2,000-13,000 eV) and new experiment hall. This expansion will provide increased capacity, enabling the LCLS to offer an ever-growing repertoire of operating configurations. As the LCLS-II Project progresses, the LCLS facility is rapidly expanding the capabilities of its x-ray source in spectral range, brightness and temporal control. SLAC is simultaneously developing options for performance enhancements (improved energy stability, higher energy, higher repetition rate) to further develop the scientific reach of the faclity.

The Linac Coherent Light Source is an X-ray free-electron laser at the SLAC National Accelerator Laboratory. It produces coherent soft and hard X-rays with peak brightness nearly ten orders of magnitude beyond conventional synchrotron sources and a range of pulse durations from 500 to <10 fs. The facility has been operating at X-ray energy from 500 to 10,000eV. Users have expressed great interest in doing experiments with X-Rays near the carbon absorption edge at 284eV. We describe the operation and performance of the LCLS in the newly established regime between 250 and 500eV.
