    "abstract": "We present pulse height measurements in drift chambers operated with Xe,CO2\ngas mixtures. We investigate the attachment of primary electrons on oxygen and\nSF6 contaminants in the detection gas. The measurements are compared with\nsimulations of properties of drifting electrons. We present two methods to\ncheck the gas quality: gas chromatography and Fe55 pulse height measurements\nusing monitor detectors.",
