Abstract

The invention discloses a time and energy double-spectrum synchronization measurement system for achieving a GHZ pulse passing rate, and the system comprises a superfast current amplifier, a superfast current / voltage converter, an FPGA module, a superfast analog switch, a charge integrator, and a superspeed analog-digital converter. Through distributing particle signals to independent and parallel quick amplitude analyzers, the system improves the processing capability for the particle signals. The system can improve the conventional superspeed digital multi-channel analysis capability by 32 times. The system solves a problem of the measurement of double parameters (energy and time) of a single particle signal with the GHz frequency. The system can reach a GHz pulse counting passing rate.

Description

technical field [0001] The present invention relates to GH Z The time and energy dual-spectrum digital multi-channel technology of pulse transmission rate, especially related to a method to realize GH Z Time and energy dual-spectrum simultaneous measurement system of pulse passing rate. Background technique [0002] Multi-channel pulse amplitude analyzer (referred to as multi-channel) is a commonly used instrument in nuclear technology applications. In recent years, digital multi-channel based on direct sampling and analysis of pulse waveform has developed rapidly. Compared with traditional analog multi-channel, it has fast analysis rate, high pulse pass rate, can detect more pulse signals, and uses programmable devices to realize flexible The advantages of data processing algorithms and so on. [0003] An analog-to-digital converter, or A / D converter, or ADC for short, usually refers to an electronic component that converts an analog signal into a digital signal. An ele...
