| 英文摘要 | Energetic particle radiation diagnoses mainly detect the particles (such as neutrons, gamma rays, hard X-rays, and escaping electrons) that are radiated in the discharge process of the experimental advanced superconducting tokamak device to characterize the operating state of the plasma in real time. The upgrading of these diagnoses requires new instruments based on national (here, "national" means developed and produced by a Chinese company) core chips and open-source software with advanced digitization, a high sampling rate, and a high time resolution. The new spectroscopy system designed in this study adopts the national field-programmable gate array (FPGA) and an analog-to-digital converter as the core chip, and it is developed using Qt on Linux. The communication between the FPGA and embedded controller occurs via a high-speed peripheral component interconnect eXtension for instrument express protocol with a direct memory access mode. On this basis, the time resolution of the system is improved from 2 to 1 ms, the maximum channel address is increased to 4096, and the sampling rate is increased from 10 to 80 Msps. Calibration experiments of the spectroscopy system with Eu-152 and Cs-137 sources demonstrate that the best energy resolution is 0.27% and the measurement error is less than +/- 0.5 keV. |
