我们测量了Ar ∶ CO_2混合气体中电子漂移速度随电场的变化。测量的混合物中含有8%至20%的CO2，增量为1%。研究了空气和氮气污染对Ar-CO2混合气体的影响。这些结果对于确定漂移室中Ar ∶ CO2混合物的正确混合比是有用的。我们还测量了几种Ar → CO_2 → CF_4混合气体中的电子漂移速度。
We have measured the electron drift velocity as a function of electric field in ArCO2mixtures. Measurements are made for mixtures containing 8% to 20% CO2in 1% increments. Effects of air and nitrogen contamination on ArCO2mixtures are investigated. These results are useful for determining the correct mixing ratio of the ArCO2mixture in drift chamber applications. We have also measured the electron drift velocity in several ArCO2CF4mixtures.
