The Linac Coherent Light Source (LCLS) upgrade to a high repetition source offers new avenues to pump/probe X-ray spectroscopies. Here I will briefly introduce the new capabilities of the LCLS focusing on the Tender X-ray Instrument (TXI). The TXI instrument is a dual-beam instrument, fed by both the soft X-ray and hard X-ray undulators of LCLS; a feature currently unique among XFEL instruments. The tender x-ray instrument will enable x-ray pump/x-ray probe techniques especially in the emerging field of nonlinear x-ray science, support tender X-ray spectroscopy measurements, and provide a coherent scattering/ forward diffraction instrument for sub-micron samples. It is designed to accommodate a variety of additional techniques, such as absorption and photoemission spectroscopy, as well as an array of samples from fixed targets to gases, aerosols, and liquid jet targets.
