Abstract
Measurements on drift velocities and collected charge were made in a small test dewar on liquid argon with admixtures of methane, ethane, ethylene and ammonia using alpha and beta particle sources. In addition a test in the Helios uranium-liquid argon calorimeter was made with a 0.35% addition of methane. The results in the Helios calorimeter showed a worsening of the hadronic resolution and the electron/pion ratio.
