8. Assembly / Testing Cables and ribbons both need assembly jigs
Cables: Karlshrue responsibility
Cables testing: ?
Ribbons: jig under design at Lyon

MFS
MPO
12 x MU
Tester
Commercially available tester
Cycles visible light along 12 fibres in ribbon
Requires MFS-MPO adapter
Transmitter + receiver: cost 3000 Euros

10. TEC integration tests Pre-integration (after LT tests)
Full check of petal functionality, including noise
Use same bench as for « debugging »
FED-PMC and FEC-PMC
« High temperature » cooling (~10 °C)
Post-integration
Same tests as above
Check each petal immediately after insertion
Final electronics
Cooling using TEC cooling circuits and 2 kW Louvain plant
Some tests (full cooling circuits) at –20 °C
