#### Vertex Tracker Barrel Parameters
- The sensor modules are 2 half-cylinders.
- There are 2 sensitive layers
- Each sensor has a thickness is 40um
- There is an outer shell for structural support 300um thick.
- The ID of this shell is set (arbitrarily) to 10 cm.
##### Sensor layers
Currently there are 2 sensor layers. Each is composed of 2 half-cylinders modules with only 40um of silicon thickness.
##### Support shell
Simple carbon fiber support shell.

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