Query: Pulse height measurements and electron attachment in drift chambers
  operated with Xe,CO2 mixtures   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 Fe55 pulse height measurements
using monitor detectors.
