过热液滴探测器对中子的声频响应

Sound Response of Superheated Drop Bubble Detectors to Neutrons

    摘要
  • 摘要: 本文主要研究中国原子能科学研究院的过热液滴探测器在252Cf中子源辐照下的气泡声音响应。通过对声音信号进行滤波预处理，得到短时信号能量、FFT频谱图、功率谱图、波形衰减时间常数，以此来确定气泡声音信号的真伪。

     

    Abstract: The sound response of the bubble detectors to neutrons by using 252Cf neutron source was described. Sound signals were filtered by sound card and PC. The short-time signal energy, FFT spectrum, power spectrum, and decay time constant were got to determine the authenticity of sound signal for bubbles.
