We describe the design and capabilities of a new Continuous Wave X-ray Excited Optical Luminescence (CW-XEOL) and Time Resolved X-ray Excited Optical Luminescence (TR-XEOL) facility on the I18 beamline at the DIAMOND light source, the UK national synchrotron facility. Experimental data from a suite of framework silicates are presented to illustrate the capabilities of the system. Experiments studied include simple (CW-XEOL) spectroscopy, (TR XEOL) lifetime experiments dose and dose rate dependence (CW-XEOL) experiments, spatial (TR XEOL) on heterogeneous sample, wavelength resolved (TR XEOL), Optically Derived X-ray Absorption Spectroscopy, (OD XAS).
