Abstract
We have measured the performances of a large (115 x 57) cm(2) planar d rift chamber filled with a He-iC(4)H(10) (70-30) mixture in a beam. Th e spatial resolution is better than 100 mu m along the whole drift cel l. Local and integrated efficiencies are 99.3 +/- 0.2% and 98.1 +/- 0. 2% respectively. The coordinate along the wire is measured by the char ge division method and the resolution at the center is 0.61% of the wi re length.
