  We have developed a series of monolithic multi-element germanium detectors,
based on sensor arrays produced by the Forschungzentrum Julich, and on
Application-specific integrated circuits (ASICs) developed at Brookhaven.
Devices have been made with element counts ranging from 64 to 384. These
detectors are being used at NSLS-II and APS for a range of diffraction
experiments, both monochromatic and energy-dispersive. Compact and powerful
readout systems have been developed, based on the new generation of FPGA
system-on-chip devices, which provide closely coupled multi-core processors
embedded in large gate arrays. We will discuss the technical details of the
systems, and present some of the results from them.
