Title: Rex C. Trammell: Innovator in Spectrometry and Gamma Detection
Introduction
Rex C. Trammell is a notable inventor based in Andersonville, TN (US). He holds a total of 6 patents that showcase his contributions to the fields of spectrometry and gamma detection. His innovative work has significantly advanced the technology used in these areas.
Latest Patents
One of his latest patents is a "Spectrometer with charge-carrier-trapping correction." This invention enhances energy resolution by correcting errors caused by charge carrier trapping. By monitoring the shape of the pulses produced by the detector, a digital filter is adjusted to improve energy resolution. This adjustment can be performed manually by an operator or automatically by an optimizer circuit, ensuring that the spectral peaks achieve a minimum width and a symmetrical shape. This correction leads to improved energy resolution by addressing energy loss associated with long rise time events.
Another significant patent is the "Method and apparatus for improving the sensitivity of a gamma camera." This invention focuses on enhancing the sensitivity of position-sensitive gamma ray detectors and gamma cameras. It addresses the challenge of small effective detector elements, which often lead to the loss of gamma rays interacting through Compton scattering. By utilizing the energy depositions from gamma rays absorbed in two separate detector elements, this method identifies valid events and improves image formation, thereby enhancing sensitivity while managing background noise.
