  • Patent number: 9500765
    Abstract: A radiation detection apparatus can include a scintillator, a photosensor optically coupled to the scintillator, and a control module electrically coupled to the photosensor. The control module can be configured to receive a pulse from the photosensor and identify a cause of noise corresponding to the pulse. Such information can be useful in determining failure modes and potentially predict future failures of radiation detection apparatuses. In another embodiment, the wavelet discrimination can be used to determine whether or not the pulse corresponds to a scintillation pulse, and potentially to identify a type of radiation or a radiation source. The technique is robust to work over a variety of temperatures, and particularly, at temperatures significantly higher than room temperature.

  • Patent number: 9024265
    Abstract: A photosensor testing apparatus can be used to test photosensors. A light module can produce simulating light that corresponds to scintillating light of a scintillator or a derivative of the scintillating light. A photosensor under test can produce an output that can be analyzed. A particular photosensor can be determined to have a higher quantum efficiency, a higher signal-to-noise ratio, or another performance criterion and selected for use in a radiation detection apparatus having the scintillator that can produce the scintillating light. The photosensor testing apparatus can provide a more accurate way of selecting a photosensor as compared to only analyzing an emission spectrum and data sheets and other information for the photosensors under consideration.

  • Patent number: 9018587
    Abstract: A radiation detection apparatus includes a sonde having a housing and comprising a scintillator disposed within the housing and a calibration source coupled to the scintillator to fluoresce the scintillator at a known wavelength of electromagnetic radiation. The radiation detection apparatus further includes an electromagnetic radiation sensing device coupled to the scintillator and disposed within the housing and a first programmable/re-programmable processing module (PRPM) coupled to the electromagnetic radiation sensing device and disposed within the housing. The PRPM can be programmed to use state information when analyzing pulses corresponding to shock, vibration, or another noise source. In another embodiment, the PRPM can be used to monitor the health of the radiation detection apparatus.

  • Patent number: 8957385
    Abstract: A radiation sensing unit for a radiation detection system can include a scintillator and a photosensor optically coupled to the scintillator. In an embodiment, the radiation detection system may provide an output signal to a particular radiation flux that is substantially temperature independent over a normal operating temperature range for the scintillator. The radiation sensing unit may further include a controllable radiation source configured to emit radiation and another photosensor coupled to controllable radiation source. A radiation detection system can include a radiation sensing unit and a control module that is coupled to the controllable radiation source and the photosensors. The control module may control the controllable radiation source and control a power supply coupled to the second photosensor in response to signals from the photosensors. In another aspect, a dynode tap from a photomultiplier tube can be used during calibration. Methods of using the foregoing are disclosed.

  • Patent number: 8866092
    Abstract: A radiation detection system can include a scintillator that is capable of emitting scintillating light in response to capturing different types of targeted radiation, a photosensor optically coupled to the scintillator, and a control module electrically coupled to the photosensor. The control module can be configured to analyze state information of the radiation detection system, and select a first technique to determine which type of targeted radiation is captured by the scintillator, wherein the first technique is a particular technique of a plurality of techniques to determine which type of targeted radiation was captured by the scintillator, and the selection is based at least in part on the analysis. In an embodiment, the radiation detection system can be used to change from one technique to another in real time or near real time to allow the radiation detection system to respond to changing conditions.
