Abstract

The invention relates to a multipath pulse signal acquisition device for use in radiation detection. A data acquisition, storage and transmission unit comprises a plurality of data acquisition, storage and transmission plates, a plurality of synchronous output signals converted by a trigger signal distributing circuit are used as the trigger input signals of the data acquisition, storage and transmission plates, and the data acquisition, storage and transmission plates are driven by the trigger input signals to process and store each collected and tested input signal and transmit each collected and tested input signal to a data receiving and storing unit; each data receiving and storing plate is used for receiving and storing the tested input signal transmitted by each data acquisition, storage and transmission plate and storing and transmitting the tested input signal to a control gate interface board; and a direct-current power supply supplies power to the data acquisition storage unit and the control gate interface board. The device solves the technical problems of limited application space and insufficient transmission bandwidth of the current quick pulse signal measuring equipment. The device can measure and display multiple signals in real time and guarantee the accuracy and reliability of the data.

Description

technical field [0001] The invention relates to a multi-channel pulse signal acquisition device in radiation detection, in particular to a measurement device for acquiring four-channel fast pulse signals and requiring real-time recording and display of measurement data. Background technique [0002] Radiation detection is to record the number of nuclear radiation particles (including γ radiation, neutron radiation, α and β radiation, etc.), identify the types of particles, measure its fluence rate and determine the energy distribution of nuclear radiation. In radiation detection, the number of radiation particles can be as high as 10 to the 30th power in an instant, that is to say, the processes of generation, maintenance, change and disappearance of these information are all "instantaneous", generally occurring in nanoseconds or even nanoseconds. within the time frame of the order of seconds. This requires the "response" of our detection and analysis system to be fast enou...
