Compact Detector as proposed for NLC

"Straw-man detector": a compact five-layer tracking system using double-sided 5$\mu$m-resolution silicon strips in B=4T. Beam pipes: 750$\mu$m thick beryllium, r=1cm near the IP and 500$\mu$m thick stainless steel for the rest. RF-shields: 200$\mu$m thick copper. Vertex detector: 4 layers of silicon+beryllium at the radii of 1.2, 2.7, 3.8 and 4.8cm with $\vert \cos \theta \vert <$0.9.
