摘要：

We present pulse height measurements in drift chambers operated with Xe,CO2 gas mixtures. We investigate the attachment of primary electrons on oxygen and SF6 contaminants in the detection gas. The measurements are compared with simulations of properties of drifting electrons. We present two methods to check the gas quality: gas chromatography and Fe-55 pulse height measurements using monitor detectors. (C) 2002 Elsevier Science B.V. All rights reserved.
