Abstract
The paper presents an LHC tracker constructed from microstrip gas counters, occupying a cylinder around the beam r=400 mm and r=900 mm. The instrument measures 12 points on track with an accuracy of 30{mu}m. Due to fine granularity and the short charge collection time, the occupancy is below 1 percent at a luminosity of L=10{sup 34}cm{sup -2}. Operating at high magnetic fields and a fast charge collection process are possible using Xe/DME/CO{sub 2} mixtures and reducing the gap width between substrate and drift cathode to 1.6 mm. Hits from low energetic tracks are largely suppressed and hard tracks stand out, which greatly facilitates pattern recognition. By introducing a small stereo angle, the (r,z) coordinate can be measured with an accuracy of 1 mm. A calculation of the collected charge per strip shows that the tracker can withstand the LHC radiation for many years. (author). 9 refs.; 7 figs.
