Abstract :
As part of our continuing program to develop a liquid argon Time Projection Chamber (TPC), we have drifted ionization electrons produced by a 113Sn internal conversion electron source over a physical distance of 20 cm in fields of 0.8 to 1.6 kV/cm. This liquid purity was maintained over a period of many days. The liquid argon purity has been improved in the liquid state by the use of molecular sieves.
