[en] The design features of the KEDR drift chamber are described. The 1 m long and 1 m outer diameter cylindrical chamber consists of seven radial super layers. The multiwire drift cell contains six sense wires with a distance of 4.5 mm. The maximum drift distance is 30 mm. Measurements of spatial resolution and aging tests were performed using DME gas with a prototype. The resolution averaged over drift distance has a value of 40 μm. The relative gain drop is equal to 45%/(C/cm). This would correspond to 2% pulse height decrease per year at a gas gain of 10⁵ and flux of the charged particles of 1 kHz/cm². (orig.)
