High-gain free electron lasers at the LCLS at SLAC and other laboratories around the world have demonstrated the power of FELs for X-rays. An oscillator-type FEL is also feasible for the hard X-ray spectral region producing fully coherent, intense X-ray pulses of high spectral purity with MHz repetition rate. It appears that an X-ray FEL oscillator (XFELO) is within the reach of current technology and, furthermore, the 4 GeV superconducting linac under construction for the LCLS-II is a suitable driver a practical XFELO. This retreat is to have an in-depth discussion of various scientific opportunities to see whether an XFELO extension of the LCLS-II complex in the future would be justified. After two and half days of intense sessions, summary presentations will be given on Friday afternoon. A written summary will be prepared in a month.
