Assumptions:

Inner Tracking Detector Sub – System (Only first and second layer)

Module size: 60mm x 60mm

Outer Tracking Detector Sub – System (third, fourth and fifth layer)

Module size: 120mm x 120mm

Modules are combined in packets of length equal to half the length of the barrel
Two packages of modules per length of the barrel.
At the end of each package is placed the SMC card ( Surface‐Mounted‐Components)

Alternative proposition – 6 layers

Additional sixth layer? Arrangement of Electronics Cards and Power Suppliers Comment: We needed to move

utward the first layer

in order to achieve more uniform distribution
