0012 #### Vertex Tracker Barrel Parameters
0013
0014 - The sensor modules are 2 half-cylinders.
0015 - There are 2 sensitive layers
0016 - Each sensor has a thickness is 40um
0017 - There is an outer shell for structural support 300um thick.
0018 - The ID of this shell is set (arbitrarily) to 10 cm.
0019
0020 ##### Sensor layers
0021
0022 Currently there are 2 sensor layers. Each is composed of 2 half-cylinders modules with only 40um of silicon thickness.
0023
0024 ##### Support shell
0025
0026 Simple carbon fiber support shell.

0052 "Support" is to "shell" like "layer" is to "module", and is need for the flat stave barrel implementation.
