Straw-based coordinate muon chamber
The article considers a prototype module with sensitive dimensions of 2 x 0.5 m2 based on 2 m long straw tubes which preserves its geometrical dimensions up to the pressure of 4 bar independently of the ambient temperature and humidity. The suggested technique provides a possibility of constructing relatively low-cost planar modules by using straw tubes as long as needed for constructing large area detectors at colliders or other field experiments by assembling them in a common coordinate detector with a user-specified acceptance. The distinguishing feature of a detector is its good radiation hardness, low radiation thickness and a possibility of optimizing the detector operation mode in a large range of gas pressure.
