  • Handheld Spectrometer
    Publication number: 20140110579
    Abstract: A lightweight handheld radiation detector for use in detecting radioactive materials, including a cylindrical vacuum housing having an inner volume, a detector material encasement disposed within the inner volume, a cooling element disposed within the inner volume and integrally formed with the detector material encasement to cool detector material within the detector material encasement.

  • Spectrometer with charge-carrier-trapping correction
    Patent number: 7312457
    Abstract: A spectrometer having improved energy resolution by correcting for error introduced by charge carrier trapping. By monitoring the shape of the pulses produced by the detector, a digital filter is adjusted to improve the energy resolution. The adjustment is performed manually by an operator or automatically by an automatic optimizer circuit that modifies the digital filter until the spectral peaks have a width and shape matching the desired characteristics, which are a minimum width and a substantially symmetrical shape. By correcting for the energy loss associated with long rise time events, the charge-trapping correcting spectrometer produces spectral peaks with improved energy resolution.
