Abstract
The main goal of the KLOE experiment is the study of CP violation in t he K mesons system, with an accuracy of 10(-4) in the measurement of R e(epsilon'/epsilon). This task imposes strong constraints on the desig n and operation of the drift chamber, which must reconstruct the charg ed decays of low momentum K-L's and K-S's with high efficiency and hig h resolution, full-length prototype of the chamber has been built and tested on a 50 GeV/c beam. The analysis of the large sample of data ha s allowed a detailed study of the time to distance relations as a func tion of the track parameters and of the peculiar geometry of the drift cell, The detector performance, in terms of efficiency, spatial resol utions and dE/dx resolution, is illustrated and discussed.
