Abstract :
The construction, digitizing electronics and results of test with cosmic rays of cylindrical drift chamber for CMD-3 detector are described. To uniformly fill the sensitive volume small hexagonal cells were chosen. The coordinate along the wire is measured by charge division technique. A resolution in the R – ϕ -plane of better than 110 μ m and about 3 mm along the wire as well as a dE/dx resolution of about 12% were obtained in cosmic test runs.
