The project of the new spherical neutral detector tracking system for experiments at VEPP-2000 e+e- collider is presented. The tracking system consists of a drift and a proportional chambers in a common gas volume. The drift chamber provides 9 measurements along the track for charged particles within 94% solid angle. Design angular resolutions for radial tracks are σφ = 0.18°, σθ = 0.3°, the vertex resolution is σR = 0.2 mm. The design of the tracking system, electric field configuration, electronics, and detector simulation are described. © 2002 Elsevier Science B.V. All rights reserved.
