Cables separation due to EMC constraints
1st idea: additional drills on the ceiling
Pros: - Minimum changes to the buildingCons: - Delicate drilling (present cable tray and TBL line to be removed, dust inside)
- Cables length > 20 m if to follow present cable trays - Problem to install new racks in the gallery- Staff in the gallery during operations
CLIC
Module
TBL
CALIFES
Shortest path from Module to Gallery
Drill only on same rows as the present pits - building structure to be preserved– drilling the ceiling is problematic (GS/SE)
Problem to install the drilling machine
Cable tray to be removed
TBL equipments to be removed
Protection from dust and water to be installed
Even more problems for cable path
Cable trenches are full on this side
Nothing authorized below air ducts level (transport vehicles)
Any other path is very long (40 m for last installed RF cables)
Lack of space in the above gallery
2.5 crates available in the vacuum alley (to be negotiated)
3 crates available in the signals acquisition alley (after some rearrangement)
Pits positions
2nd solution: drill the wall towards CTF2
Pros: Simple drilling (Clear area, enough space for dust confinement)Possibility to install racks where are the disused 30 GHz racksOperations from a safer gallery (but still close to the X-Box1)
Cons: Long cable length (>> 20 m, inside CLEX electronics required)Radioprotection of the CTF2 area to be investigated
CLIC
Module
TBL
CALIFES
Cables path towards CTF2
Possible drillsMore clearance but iron wall to be moved
Possibility to add a cable tray under the ceiling but long path to reach the module (13 m to the wall)
Only 3 crates available in the gallery above CTF2 if disused 30 GHz electronics is removed
Best choice: dedicated shelter on the car park
Pros: Easiest drilling solution (from outside, minimum dust, clear area inside)Shortest possible cables length (< 20 m)Sufficient place to host the new racksSafe and comfortable operations inside the shelter (outside of the controlled area)
Cons: New construction (Algeco 1 kCHF/m2) with all services (air conditioning ?)Radioprotection of the car park to be investigated by RP

Shelter
3 x 5 m
From Module to car park wall
- Easy drilling of 6 holes (diam. 160 mm) with slope for RP- Still 2 m of trench to be cut to reach the wall
- 0.400 x 0.180 m fully available trench- 3.8 m to the wall (2.8 m thick)
Alternatively use of the ventilation window chicane instead of drilling new holes (to be investigated)
A shelter on car park side
5 x 3 m available
Example of a present shelter (high voltage electronics for TL2 tail clipper)
Ventilation window
Possible shelter arrangements

4 x 3 m shelter
ConclusionThe shelter on car park solution allows:- Minimal cable length and easy cables pulling (also a cost issue for “good” RF cables)
- Easy crates installation and safe operations (outside controlled area)
- Easy drilling of the holes (less building structure concern, drill from outside)
- Alternatively possible use of the ventilation window (under investigation by Y. Body – EN-CV)
- Possibility to displace some electronics cabinet inside for Rad-Hard tests
- Requires cable trench extension (feasibility checked with (GS/SE) )
- RP to give the green light (G. Dumont contacted)- Decision to be taken by March 2014
