光电倍增管增益 multiplier gain
- 为避免产生光子并合现象的产生,可以利用在接收光路上加装中性衰减片、提高光电倍增管开始工作的高度和降低光电倍增管增益等措施来分段测量,提高臭氧测量的精度。
To avoid the phenomena of photon overlap, many measures such as neutral optical attenuator, gate witch and reducing the gain of PMT, are taken to enhance accuracy of ozone measurements. - 实验比较了高计数率下三种光电倍增管电压供给方式的增益变化和温度效应。
The gain stabilities and temperature effects were experimentally for three different bias voltage supply modes to photomultipliers at high counting rates. - 由于IC CD器件的成本较高,本论文设计了用光电倍增管进行增益调制的原理验证性实验。
As ICCD device costs high, based on analysis of existing photoelectric detector, we choose photomultiplier tube as a substitute for the principle verification experiment.
