Once the shell has been mounted on the integration bench the next operation is the preparation |
| 46 |
|
of the Control Ring cables. |

As described in section \ref{fig:ctrlring} the readout clock, |

which is not protected by the carbon fiber plate |
| 83 |

is shielded using a thin Aluminum foil. |

The small AOH board ($3\times 2.2 cm^2$) |

|
is simply screwed to a C-shaped ledge which is directly glued on the string cooling |

|
pipes. Due to mechanical constraints the |

|
The Mother Cables are inserted into the structure when the AOH have been mounted and the optical |
| 133 |
|
fibers fixed to the shell and protected. This procedure is in some cases complicated by mechanical |
| 134 |
|
constraints at the level of the shell front flange, where the mother cables are entered in the shell, |
| 222 |
|
When a string of three modules has been mounted the I$^2$C communication are again verified and |
| 223 |
|
a noise run, at 400V bias, is taken. For the tests complete description see section \ref{sec:Tests}. |

The TIB control electronics, which distributes clock, trigger and I$^2$C signals to the modules, |
| 227 |
|
is located on a carbon fiber support mounted on the shell external surface |
| 228 |
|
just above the modules. |
