0014 #### Vertex Tracker Barrel Parameters
0015
0016 - The sensor modules are 2 half-cylinders.
0017 - There are 2 sensitive layers
0018 - Each sensor has a thickness is 40um
0019 - There is an outer shell for structural support 300um thick.
0020 - The ID of this shell is set (arbitrarily) to 10 cm.
0021
0022 ##### Sensor layers
0023
0024 Currently there are 2 sensor layers. Each is composed of 2 half-cylinders modules with only 40um of silicon thickness.
0025
0026 ##### Support shell
0027
0028 Simple carbon fiber support shell.

0054 "Support" is to "shell" like "layer" is to "module", and is need for the flat stave barrel implementation.
