Abstract :
For the outer tracking system of the LHCb spectrometer 53.760 straws of 2.5 m length will be used. They are arranged in detector modules of 5 m length and 0.34 m width. The envisaged spatial resolution over the entire active area is 200 μ m resulting in stringent requirements on the accuracy for the module construction. s paper we discuss the optimisation of the straws, design and construction of detector modules. The long-term operation properties of straws in two different counting gases, Ar/CO 2 (70/30) and Ar/CO 2 /CF 4 (75/10/15), are compared.
