摘　　要：研制了一台可调整脉冲电源 ,并用于空心阴极放电管读取 5L6 16 90 0 7M7的光电流光谱。调整脉冲电源的脉冲宽度、脉冲频率、直流偏压以及输出电压等参数 ,记录读取光电流信号及光电流光谱 。A programmable-pulsed power supply of hollow cathode discharge tube (HCD) for optogalvanic spectroscopy is fabricated. The optogalvanic signal of transition 5L6-16900 7M7 is measured. By adjusting the pulse width, pulse frequency, DC bias, as well as the output voltage, the optogalvanic spectra are obtained with good qualities. Spectra obtained by using different parameters were compared and discussed.
