Abstract

The invention provides a double-exponential nuclear signal counting method and device, and relates to the technical field of nuclear signal processing, and the method comprises the steps: obtaining ato-be-counted double-exponential nuclear signal; inputting the to-be-counted double-exponential nuclear signal into a pre-established transfer function, and obtaining an impulse signal output by the transfer function; and counting the to-be-counted double-exponential nuclear signal according to the impulse signal. In the implementation process, the to-be-counted double-exponential nuclear signalsare input into thepre-established transfer function, the output signals are impulse signals with short dead time, a sampling period is occupied, and the double-exponential nuclear signals are accurately counted by identifying the accumulated nuclear signals.

Description

Technical field [0001] This application relates to the technical field of nuclear signal processing, and in particular to a double-exponential nuclear signal counting method and device. Background technique [0002] To obtain accurate nuclear information in nuclear science and technology, it is often necessary to detect nuclear signals with electronic methods and extract nuclear information from them. With the development of high-speed digital processing chips and high-speed ADCs, nuclear signal digitization and its digital processing technology gradually mature. However, in the case of high counting rate, the accumulation of nuclear signals is more serious, which makes the counting accuracy of nuclear signals greatly reduced. In order to obtain more accurate count rate information, the current main solutions include: reducing the width of the nuclear signal, maximum likelihood estimation, and single exponential impulse shaping. However, the nuclear signal output by these metho...
