The EIGER X 500K Hybrid Photon Counting (HPC) detector utilizes the 4 and 8 bit readout capabilities of EIGER to provide never reached frame rates in a compact housing. “Until now, synchrotron experiments examining processes far below the millisecond range have only been possible via complicated pump and probe techniques. At DECTRIS we are pleased we can now empower scientists to investigate this time scale with continuous exposures and a temporal resolution of 112 microseconds”, comments Stefan Brandstetter, Product Manager Synchrotron at DECTRIS and adds: “XPCS measurements crucially depend on high temporal and spatial resolution. With small pixels and a frame rate of up to 9000 Hz with a dead time of only 3 µs, EIGER X 500K is the perfect detector for XPCS measurements.”

The system offers noise-free single-photon counting with a sensitive area of 37 mm x 77 mm and a pixel size of 75 µm. The well established control interface remains unchanged and allows for an easy and fast integration with beamline software. The ultra-fast EIGER X 500 is available with optional vacuum compatibility.
