Abstract
The 1 m long and 1 m outer diameter chamber consists of 42 layers. The chamber is based on a cell of the jet type with drift distance of 30 mm. The measurements of the spatial resolution and the aging tests were performed with DME gas on prototypes. The resolution averaged over the drift distance has a value of 45 μm. The relative gain drop is equal to 45%/(C/cm). The design and construction of the chamber, the gas system, the laser calibration system and first results of the cosmic-ray test are discussed.
