The operation and technical capabilities of a new mobile luminescence end-station (MoLES), available for public use at the Daresbury synchrotron radiation source, are described. The system is ideal for the measurement of luminescence emission, optical detection of XAS (OD-XAS) and pump–probe experiments of solid-state samples over the temperature range 8–330 K, excitation range 5 eV to 70 keV, and photon emission range 1.2–6.5 eV.
