A new universal, flexible firmware has been implemented on field -programmable gate array (FPGA) for gamma-ray spectroscopy. The firmware of the FPGA runs on a digitizer that we developed ourselves. The present paper describes the detailed architecture of the firmware, including the trapezoidal shaper, peak detection, pulse height analyzer, and pile-up rejection. Gamma-ray spectroscopy measurements are made using a NaI(Tl) detector, CdZnTe detector, and HPGe detector.
一种新型的通用、灵活固件已在现场可编程门阵列(FPGA)上实现,用于伽马射线能谱分析。FPGA的固件在我们自行开发的数字化仪上运行。本文描述了固件的详细架构,包括梯形整形器、峰值检测、脉冲高度分析器和堆积脉冲剔除。使用碘化钠(铊)探测器、碲锌镉探测器和高纯锗探测器进行伽马射线能谱测量。
