Tracking

The particle tracking is performed by the V$_1$ and V$_2$ detectors. A charged particle passing through one of these detectors produces a signal from a single ring and a single sector.

The intersection between the hit ring and the hit sector determines the impact point of the particle on the detector. Then two detectors allow the complete reconstruction of the particle trajectory.

The polar and azimuthal emission angles resolution depends on the ring pitch and on the sector opening angle respectively.

Thus the detector geometrical parameters were chosen to have the required resolutions which are expected to be $\sigma(\vartheta)\simeq 1^\circ$ and $\sigma(\varphi)\simeq 10^\circ$ according to simulation.
