With a 50 μm pixel size, the SLAC developed ePix100 provides one of the highest resolutions of all the detectors available at LCLS. Used in both soft and hard X-ray applications, multiple ePix detectors can be installed and read in-sync in order to expand the cross section covered by the detectors.

The camera dimensions are 2 x 2 x 11.5 inch (5.1 x 5.1 x 29.2 cm), including tubings and connectors.
