Basic research, medical diagnosis and treatment, nuclear power production, radioactive waste disposal, and nuclear security require high-sensitivity, high-resolution radiation detectors operating in field conditions and at ambient temperatures. Brookhaven’s Instrumentation Department is developing several types of room-temperature semiconductor detectors and advanced electronics that can support such applications. Our Capabilities - Optimization of pixelated, coplanar-grid, and virtual Frisch-grid detector configurations and readout electronics for high-resolution spectroscopy and imaging of gamma-ray sources - Characterization of detector materials with nondestructive techniques—for example, 3-D infrared transmission microscopy and high-resolution x-ray response mapping—to identify causes of material nonuniformities and provide feedback to crystal growers - Identification and investigation of crystal defects impacting detector performance via x-ray beams at Brookhaven’s National Synchrotron Light Source II - Integration of multichannel low-noise readout electronics and advanced signal processing systems
