Embodiment 1

[0035] This embodiment provides a system for automatically acquiring data, such as figure 1 As shown, it includes a microcomputer 1 and a drive module 2, the microcomputer 1 can be a computer, and the microcomputer includes a data acquisition module 11 and a reaction target control module 12, and the data acquisition module 11 and the reaction target control module 12 communication connections, the reaction target control module 12 is electrically connected to the drive module 2, the data acquisition module 11 includes a sending module 111, a collection module 112 and a data writing module 113;

[0036] The white light neutron source produces a neutron beam, which bombards the reaction target. The reaction target can be a metal target, pure physical material or powder, etc. Some neutrons are reflected back by the reaction target, and some neutrons pass through the reaction target and are released. The detector detects a pulse waveform of neutrons formed in the detector after b...

Abstract

The invention discloses a system for automatically obtaining data, and the system comprises a drive module, a data obtaining module, and an reaction target control module. The data obtaining module is in communication connection with the reaction target control module, and the reaction target control module is electrically connected with the drive module. The data obtaining module comprises a transmitting module, a collection module and a data writing-in module. The transmitting module is used for transmitting a target change signal to the reaction target control module. The reaction target control module is used for the all of the drive module after the target change signal, and transmits a feedback signal to the collection module after the drive module completes the target change. The collection module is used for collecting a waveform signal of particles, and the data writing-in module is used for writing the energy representation data of particles into a file, and carries out the call of the transmitting module. The system can automatically change the reaction target according to a preset sequence, automatically records a file formed by the data that the particles bombards the reaction target, avoids a problem that a mode of manually recording the cross-section data of particles is liable to cause an error, and improves the efficiency of data obtaining.

Description

technical field [0001] The invention relates to a system for automatically acquiring data. Background technique [0002] The white light neutron source experiment uses the neutron time-of-flight method to accurately measure the energy of neutrons, and carry out cross-section measurements of neutron nuclear data, such as the measurement of total cross-section and capture cross-section. Among them, when measuring the total cross-section, it is necessary to analyze the cross-section data of neutrons with and without reaction targets. In order to avoid the influence of accelerator stability and changes in background conditions under long-term measurement conditions, the The accuracy of the measurement requires statistical analysis of a large amount of cross-sectional data formed under the neutron bombardment reaction target to obtain a qualitative analysis of the law of the material of the reaction target. Therefore, it is necessary to constantly replace different reaction targe...
