介绍了一种改进型NaI(Tl)γ谱仪的稳谱技术.该稳谱技术基于241Am源的等效γ峰作为系统的参考峰,根据参考峰位偏差运用数字PID调整可编程增益放大器来稳谱,是一种"硬件+参考源+软件"的稳谱技术.这种计算机稳谱技术具有稳定度高,稳谱速度快等优点.

This paper introduces an improved technology for spectrum stabilization of NaI(Tl) gamma spectrum. This technology is based on the system using a reference peak, which is equivalent gamma peak of 241Am source. The computer seeks peak's position deviation and computes adjust value of programmable amplifier and controls programmable amplifier to stabilize spectrum by digital PID. This is a technology of spectrum stabilizing with hardware + reference-peak + software an...
