Abstract: A system for cyclical noise removal from a transient signal is employed with a transient sensor for a signal. A signal conditioner is connected to the transient sensor for processing the signal. A transient digitizer captures the processed signal including capture of a sufficient period of time before the transient to accurately analyze the cyclic noise, capture of a period of time to be sure the transient is not effecting the ambient and capture of the period of the transient. A signal processor is employed for filtering of a non-cyclic transient signal. An embedded computer with associated software performs an analysis of the ambient background just prior to the time that the transient signal of interest is detected, performs an analysis of the signal of interest, extends the analyzed ambient background signal through the period of time during which the transient signal is occurring and subtracts the background from the transient signal.

Abstract: A spectrometer system employs a gridless Xenon detector having an anode and a cathode supported in spaced relation from the anode devoid of structure intermediate the anode and cathode. Pulses resulting from charge collection due to radiation ionization of the Xenon gas are detected and parametrized by a computation engine through multiple detected pulses. Simultaneous determination of the position and ionization energy allows selective presentation of the data to compensate for various position dependent phenomena.
