Breadboard of a gamma-ray detector system (IMAGE) NASA/Goddard Space Flight Center Caption This is a breadboard of a gamma-ray detector system that Principal Investigator Regina Caputo and her team assembled to test pixel-based silicon detector technology. The actual detector, provided by Argonne National Laboratory, is the rectangular piece positioned on the vertical board. The final design will be custom made and simpler.
