Abstract 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 σ φ =0.18°, σ θ =0.3° , the vertex resolution is σ R =0.2 mm . The design of the tracking system, electric field configuration, electronics, and detector simulation are described.
