Optimized Design of the Neutron Source Data Acquisition and Processing System

In neutron source experiments, electrode breakdown events frequently occur, leading to operational anomalies. To improve the functionality of the neutron source data acquisition system, optimizations and enhancements were implemented. A breakdown detection board was added to the acquisition module design to monitor breakdown events in real time and send the breakdown signals as triggers to the acquisition system. To conserve system storage resources, the system is designed to perform high-frequency data acquisition during breakdown events and switch to low-frequency acquisition when no breakdown occurs. The Model Driven System Plus (MDSplus) data model was customized for the data storage module, effectively compressing the storage space required for neutron source data. Additionally, waveform data from one second before and after the breakdown event can be visualized separately, with a sliding zoom feature for detailed analysis. Testing shows that the optimized system meets experimental requirements, allowing researchers to more easily observe breakdown waveforms and frequency. This enables timely adjustments to the neutron source accelerator's electrode spacing, reducing the likelihood of breakdown events.
