摘要：

The spatial resolution of a liquid xenon ionization chamber operated in the time projection mode was measured with a multiwire anode structure, using cosmic rays traversing a maximum drift gap of 5.9 cm. From the digitized pulse shape of the ionization signal induced on the anode wires, the timing information was measured for different track orientations in space. In order to estimate the resolution capability of the chamber, tracks entering the chamber at about 50-degrees with respect to the horizontal were selected, as they would most likely induce a signal on all the wires. The accuracy on the measured drift time, limited mostly by electronic noise and electric field shaping, translates into a spatial resolution of 180-mu-m rms for the z-coordinate along the drift direction.
