Standard configuration for 8th user call

We encourage users to submit proposals to use the liquid jet installation at FXE to perform non-resonant X-ray emission and scattering in parallel. This experimental station has been well established for measuring ultrafast dynamics of species in solution at repetition rates up to 500 kHz and time resolution of 100 fs. Typical measurements have often included X-ray emission of 3d metals, including simultaneous measurements of multiple lines simultaneously. We anticipate successful proposals will be allocated between 3 to 4 16 hour shifts. For proposals that may require parameters outside the ranges mentioned below please contact the instrument directly to clarify the specific details and determine your experiment’s compatibility with the standard configuration.
