摘要
采用塑料闪烁体和光电管研制了缓发中子坪探测器,该探测器具有高线性度、限幅保护和高频噪声抑制的特点。高线性度保证了测量的准确性,限幅电路保护了后续电子学设备,高频噪声的抑制提高了测量信噪比,在CFBR-Ⅱ堆爆发脉冲实验中测量得到了缓发中子坪功率曲线。
The detector of decay neutrons plateau is developed and manufactured with scintillator and photoelec- tric tube. Its characteristics are high linear current, protection of amplitude limiter and suppression of high fre- quency noise. The high linear current improves measurement precision. The amplitude limiter protects the elec- tronic equipments and improves signal to noise ratio. The power curve of decay neutrons plateau is measured by the detector in experiment of burst at CFBR - II.
