For more than a decade, the Instrumentation Department has been developing high-performance diamond radiation detectors for a variety of applications, including proton beam flux monitoring and synchrotron x-ray imaging. The radiation hardness of diamond makes the detectors adept at measuring protons, alpha particles, and other charged particles for applications in medicine and nuclear nonproliferation. Because of diamond’s high charge-carrier saturation velocity, these detectors are also ideal for ultrafast (picosecond) detection in intense radiation environments. Our Capabilities - Fabrication of a range of diamond sizes, from standard (4.5 × 4.5 mm with a 20–500 μm thickness) to thin (5–10 μm) - Demonstration of detectors with linearity-of-flux measurements over 11 orders of magnitude and a sub-picoampere leakage current - Deposition of different metals via thermal processing, electron-beam evaporation, or sputtering - Generation of ultra-nanocrystalline diamond (UNCD) electrical contacts via patterning - Application of capabilities in our in-house High-Density Interconnect Laboratory (HDIL), printed circuit board design facility, and sensor packaging machining facility
