摘　　要：核辐射探测器是一种用于监测辐射水平的仪器,对放射源所辐射出来的高能粒子进行探测。然而,这些探测器在进行探测工作时需要稳定、可靠的电源来确保其正常运行。为了更好地满足不同类型的核辐射探测器对电源的要求,设计了一种基于能谱测量的多路输出精密稳压直流电源。首先,利用EDA软件绘制电源的原理图,然后选择合适的元器件对电路板进行焊接和调试,并使用示波器观测噪声的大小,从而判断电源性能好坏。实验表明六路输出的电压误差范围是(0.07±0.055)V。示波器观测到六路输出电压的噪声范围为(12.46667±2.77609)mV。从测试的电压数据上可以得到,最小电压的电压噪声小于9 mV。该电源性能良好,能够满足半导体核辐射探测的需要,为相关核辐射探测器提供了一个稳定的电源。Nuclear radiation detector is an instrument used to monitor radiation levels,detecting the high-energy particles emitted by radioactive sources.However,these detectors require stable and reliable power supply to ensure their normal operation during detection work.In order to better meet the power requirements of different types of nuclear radiation detectors,a multi-channel output precision regulated DC power supply for nuclear energy spectrum detection is designed.First,EDA software is used to draw the schematic diagram of the power supply,then the appropriate components are selected to weld and debug the circuit board,and the oscilloscope is used to observe the noise,so as to judge the performance of the power supply.The experiment shows that the voltage error range of the six-channel output is(0.07±0.055)V.The noise range of the six-channel output voltages observed by the oscilloscope is(12.46667±2.77609)mV.From the voltage data of the test,it can be obtained that the voltage noise of the minimum voltage is less than 9 mV.The power supply has good performance and can meet the needs of semiconductor nuclear radiation detection,providing a stable power supply for related nuclear radiation detectors.
