Content

We are presenting a drift chamber composed from three layers of mylar drift tubes with outer diameter 15 mm. The tubes are made of mylar film 125 micrometers thickness covered with aluminium from both sides. Length of tubes is 560 mm. A ingle tube is self-supported structure withstanding 350 g wire tinsion without supports an internal overpressure. It was assembled 350 such tubes. Disign, quality control procedures of drift tubess is preented. Seven chambers were glued from these tubes. Each chamber consists of 3 layers, 16 tubes per layer. A few chambers were tested with cosmic rays. Results of the tests, counting rate plateau and coordinate resolution are presented as well.
