Abstract :
The construction, digitizing electronics and results of test with cosmic rays of cylindrical drift chamber for CMD-3 (Cryogenic Magnetic Detector) detector are described. To uniformly fill sensitive volume small hexagonal cells were chosen. A coordinate along wire is measured by charge division technique. Resolution in R – φ -plane better than 100 μ m and about 2 mm along wire as well as d E / d x resolution about 12% in cosmic test runs were obtained.
