用吸收光谱法测量COIL的水汽含量
Measurement of water vapor content in COIL by absorption spectroscopy at 1 392 nm
摘要
分析了利用吸收光谱法测量氧碘化学激光器的水汽含量的原理,在氯气流量为0.1 mol/s的N2-COIL上进行了测试实验.实验结果显示,在常规工作条件下,由于BHP温度变化所引起的水汽百分含量变化仅为0.1%,可以忽略;水汽含量随稀释气体流量增大而增加,气体流速是引起水汽含量变化的主要原因,实验中应把氯气和氧气的比例控制在4∶1之内.
Abstract
We measured the water vapor fraction in COIL by absorption spectroscopy. Measurements showed that the change of water vapor fraction due to the basic hydrogen peroxide（BHP）temperature could be ignored during normal operation. The water content rises with the increasing of buffer gas flow rate. It is indicated that the gas flow velocity is the main reason that affects on the water vapor
fraction in COIL.
