A specially designed cryostat apparatus was built to operate a liquid argon ionization cell with very low acoustic noise. The cryostat was equipped with a system to damp out low frequency vibrations and thus reduce induced acoustic noise on the data transients. A liquid argon ionization cell was tested in the new cryostat by measuring the ionization of the argon by cosmic ray muons. Digital filtering of the individual data transients improved the purity of the data set used to generate ensemble averaged transients for different electric fields across the ionization cell. Transient waveform analysis was used on these averaged transients to extract the mean electron lifetime of the ionization electrons drifting in the liquid argon. A result ...
