Latest Patents
One of his latest patents is a highly sensitive nuclear spectrometer apparatus and method. This nuclear spectrometer employs asymmetrical weighting functions to optimize energy resolution and throughput. Photons striking a semiconductor detector generate current, which is amplified, converted to a voltage step, and fed to a fast analog-to-digital converter (ADC) for pile-up rejection. A slow ADC examines the output for low-energy pile-up, slope corrected, and buffered for photon energy measurement. Pile-up is detected using a unique pair of leading and trailing weighting functions, whose outputs have sharp rising and falling edges, nearly independent of photon energy. Digital triangular shaping is utilized to locate the step in the buffer, and asymmetry of the triangular response is used to reject very low-energy pile-up. The step is also rejected if the average noise nearby exceeds a threshold. When a valid step is located, the buffered data stream surrounding the step is multiplied by an asymmetrical pair of leading and trailing weighting functions. The leading weighting function has a cusp shape that peaks at the gap surrounding the step, while the trailing function has its peak shifted slightly away from the gap. A multi-channel analyzer attached to the weighting function circuit bins the measured photon energies to accumulate a spectrum.
