1 - large solid-angle multiplicity detector ( Si pad detector) :
- Octagon : (around the beam pipe)
- 6 Rings : (placed at 1 , 2 , 4 meter)
2 - Vertex finding detectors (Si pad detector) :
above and below the beam pipe line around the interaction region.
3 - two spectrometer arms (Si pad detector) :
- Positioned on either side of the beam. Each arm has 15 planes of
Silicon pad detectors, (7) in 2T magnetic field.
- provide particle identification for higher particles exiting
- Plastic-Scintillator Paddles (16 each array ) :
- Cerenkov rings (around beam pipe ) :
