High Repetition-Rate X-Ray Pulse Selection at Synchrotron Sources

Hard x-ray research taking advantage of both the coherence and timing properties of next generation low-emittance storage rings will thrive in exploring the spatial and temporal correlations at the nanometer and nanosecond scales. Current gating technology with fast detectors and mechanical choppers will not be able to handle the high repetition-rates of these sources and requires the development of a fast gating device that can fill the needs of the timing community. Here, we introduce a MEMS device that has the potential to meet the future requirements of x-ray timing science. We demonstrate a device that is frequency matched to the operating sub-frequency of a high rep-rate bunch mode at the APS (Advanced Photon Source) to select single pulses from the pulse train with separations of similar to 153 ns.
