  • Patent number: 10156642
    Abstract: The present specification describes an improved multi-energy radiation detector. In one embodiment, the signal generated by the detection medium is converted to digital form directly at the point of signal collection. This avoids the need for power intensive high bandwidth amplifiers and analog-to-digital converters, as it integrates the sensing device and signal processing onto the same silicon substrate to reduce the number of components in the system. In one embodiment, a single photon avalanche diode (SPAD) is coupled directly to a threshold detector to achieve an intrinsically low power and low noise detector.

  • Patent number: 10139496
    Abstract: A multi-radiation identification and dosimetry system and method that allows for monitoring of alpha, beta, and gamma radiation is disclosed. The system/method incorporates a segmented silicon drift detector (SSDD) that allows measurement of directly absorbed radiation in the semiconductor (betas, conversion electrons, Lx lines, and alphas) on one SSDD segment and radiation from a radiation scintillation detector (RSD) on multiple segments of the SSDD. With the anode side of the SSDD directed toward the radiation inspection surface (RIS), the SSDD+RSD stacked radiation detector collects radiation which is processed by a charge sensitive amplifier (CSA) and then processed by a time stamping differentiator (TSD). A computing control device (CCD) may be configured to collect the time stamp differentiation data from the various SSDD segments to permit the simultaneous discrimination of several types of radiation by and presentation of these radiation types and counts on a display monitor.

  • Patent number: 10031092
    Abstract: The system for determining and imaging wax deposition and corrosion in pipelines relate to systems for determining wax deposition and corrosion by one or both of two techniques. In both techniques, a source of neutron radiation is directed at the pipeline. In one technique, a neutron detector surrounded by an absorption shield defining a collimation window counts neutrons reflected back to the detector by back diffusion or backscatter radiation. In the other technique, a gamma ray detector measures gamma rays emitted when the emitted neutrons are absorbed in the pipeline. A neutron moderator-reflector is placed around three sides of the pipeline to increase the likelihood of neutron capture. A gamma detector surrounded by a gamma absorption shield defining a collimation window counts neutron capture gamma rays. An energy window can be taken for selection of Fe and H gamma rays for high precision imaging.
