Characterization of the effect of plastic gas pipes with the use of a Single Wire Proportional Chamber

Plastic gas pipes are widely used in experimental setups for gaseous detectors, due to their flexibility and easiness of use. This report describes the characterization studies realized on the use of plastic gas pipes, particularly in relation to the accumulation of impurities in gas systems that they may cause. A laboratory setup has been implemented to evaluate the possible effects caused by plastic pipes, in terms of their specific impact on O2 and H2O accumulation and the consequences on detectors performance. As Single Wire Proportional Chambers are very sensitive to the presence of pollutants and gas mixture variations, this type of detector was chosen to perform the study.
