Abstract
We have measured the electron drift velocity as a function of electric field in Ar-CO2 mixtures. Measurements are made for mixtures Containi ng 8% to 20% CO2 in 1% increments. Effects of air and nitrogen contami nation on Ar-CO2 mixtures are investigated. These results are useful f or determining the correct mixing ratio of the Ar-CO2 mixture in drift chamber applications. We have also measured the electron drift veloci ty in several Ar-CO2-CF4 mixtures.
