Abstract
The attenuation length of drifting electrons in liquid argon doped with 50 ppm of allene and its time variation have been investigated by using a dual type gridded ionization chamber. The attenuation length changed from 1.1 m as initial value to longer than 2 m after 20 hours in an electric field of 1.0 kV/cm, while the amount of collected charge decreased with time. The reason why the charge collection yield in liquid argon doped with allene is degraded with time is discussed.
