System and method for testing signal of detector

Abstract

The invention provides a system and a method for testing a signal of a detector. The system comprises a detector signal processing module, a pulse information collection module and a control module, wherein the detector signal processing module is used for outputting a digital pulse signal according to a comparative result of an analog signal output by the detector and a reference level threshold; the pulse information collection module is connected with an output end of the detector signal processing module and used for connecting the digital pulse signal; and the control module is connected with the detector signal processing module and the pulse information collection module respectively and used for determining the reference level threshold and testing a peak value and / or a noise threshold of an analog signal output by the detector according to a collection result of the digital pulse signal. The system is simple in structure, small in design difficulty and low in cost.

Description

technical field [0001] The invention relates to the technical field of detector testing, in particular to a detector signal testing system and method. Background technique [0002] In the field of high-energy physics, the main research objects are X / γ-rays and various microscopic particles. The main method is to develop corresponding detectors for detection experiments, such as gas detectors, scintillator detectors, and semiconductor detectors. In order to ensure that the experimental results are credible and reliable, it is necessary to design corresponding calibration test systems and calibration test methods to calibrate the performance of these detectors, for example, to calibrate the performance of the detector system output signal peak value, noise threshold, and energy response. [0003] In high-energy physics detection experiments, the energy information of the incident particles is usually the most concerned, that is, it is usually necessary to test the output signa...
