| • | angular coverage of almost 94% of 4p |
| • | good angular resolution, fundamental also in the reconstruction of kinematical variables and in the study of particle-particle correlation; |
| • | identification in mass and/or charge of the detected particles; |
| • | low detection threshold and high dynamical range in energy; |
| • | direct velocity measurement for all the particles above the detection treshold; |
| • | total reconstruction of the event even for high particle multiplicity (<=40). |
