摘要：

Big planar drift chambers built for the downstream tracking system of the HERMES spectrometer are described. Using the fast non-flammable gas mixture Ar/CO2/CF4 (90/5/5) average spatial resolutions of about 180 mu m per plane at efficiencies above 96% have been obtained from test run data analysis.
