A New Scintillation Detector with Silicon Photomultiplier Coupling



Technology Description


This technology is a high-resolution, low-power, and low-noise radiation spectrometer. It is an ideal solution for any situation where a compact and high-resolution photon detector is needed. The device provides a novel coupling of a luminous inorganic scintillating crystal to a light collection device with integrated passivated planar silicon for electron detection. The unique profile of the crystal allows for the use of silicon photomultipliers (SiPMs), which are modular, rugged, low-power, and significantly more compact than photomultiplier tubes (PMTs). This device provides high resolution at lower power for a fraction of the cost as compared to available gamma spectrometer technologies.


Features & Benefits


  • low power & inexpensive
  • compact and portable
  • high resolution & sensitivity




  • gamma spectrometry
  • detection of radioxenon isotopes
  • security and screening


Background of Invention


The release of certain radioxenon isotopes in certain ratios are key markers of a nuclear detonation. By monitoring the atmosphere for these markers, the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) can conclusively identify nuclear tests regardless of location. Many radioxenon detection systems currently employed by the CTBTO make use of archaic technologies with many shortcomings, including mediocre energy resolution, bulky electronics and detectors, and high cost. Therefore, a new radioxenon detection system utilizing modern technologies and approaches to identify the betagamma coincidence decays of these radioxenon isotopes is needed to address these shortcomings.
