ePixS is a novel multichannel X-ray spectroscopy detector that can deliver Silicon Drift Detector (SDD) like performance at strobed x-ray sources (X-ray FEL), where it can measure a spectrum on a pulse-by-pulse basis. It is based on hybrid architecture with p-i-n diodes flip-chipped bonded to mixed signal integrated circuits. The ePixS ASIC from which the detector takes the name, is the latest addition to the class of x-ray signal processors named ePix and has an equivalent input noise of 8 e- r.m.s. at room temperature. The full detector is typically operated at -40° C where it shows a noise floor of 12 e- r.m.s. at nominal 32µs integration time. The first generation offers 4 10x10 pixel sub-arrays with a pitch of 500 µm. The system is scalable to 10,000 pixels and can sustain a frame rate of 30kHz. Since it has an electronic shutter, sub arrays can also be phased to achieve an 100 kHz effective frame rate. Although intended for LCLS, it is a natural fit to the requirements of other FELs and offers significant advantages over an array of SDDs in terms of cost, data acquisition, and system complexity, while providing similar spectral resolution. The large channel count drastically reduces the time required to take a two or three-dimensional scan of a sample allowing more experiments to be performed in a given period. The detector can be also operated at synchrotrons, showing performances comparable to SDDs in terms of resolution and, because of the fine segmentation, with higher throughput. The system and results from prototypes will be presented.
