Current Status:

Wafer Type

Number of sensors in the setup

Number of channels per Wafer

Octagon Multiplicity

13(rings) x 8(octa) -12(spectrometer and Vertex open) =

92

2 x 32 =

64 ch

Multiplicity Rings

6(rings) x 8 =

48

2 x 32 =

64 ch

Inner Vertex Detector

2(top/bottom) x 4 =

8

2 x 192 =

384 ch

Outer Vertex Detector

2(top/bottom) x 8 =

16


192 ch

Multiplicity Total: 8920 channel

Vertex Total: 6144 channel
