One of the detectors and readout electronics undergoing testing at the MSFC X-Ray Astronomy Laboratory. The 16x16 300 micron pitch detector is in the center of the lightly-shaded region at right-of-center. The Application Specific Integrated Circuit (ASIC) readout chip consists of a Pixel Array Chip (PAC5) bump bonded directly to the CdZnTe crystal and two Shaper And Multiplexer Read-Out Chips (SHAMROCs) visible at either side of the crystal.
