Copper cabling & connectors I• Existing cable database: re-use

very useful features: naming convention, barcodes• Re-cycle existing cables• Remove cables…..? eg Velo Cu signals• All between detector & D2/D3/B1 (none to surface)

Common cable typesMaraton 380VDC + monitoring/controlCANbus for ELMBs

Sub-detector specificeg multiwire HV for silicon detector biascoax for PMT signals

Upgrade infrastructure, 19-20 Feb 20154Ken Wyllie, CERN

Copper cabling & connectors IINew cables:

Choose cables/connectors available through CERN storesEasy purchasing & delivery (careful with delivery times)Unused length can be returnedMost meet safety regulations (IS-23)

Must be carefully specified & documented in EDMS

Long-distance cables: purchasing & installation by infrastructure group

(sub-detector budget codes!)Short-distance cables:

sub-detector responsibility (help from infra-group)

Power supplies

Re-cycle existing unitsAssume maintenance contract extended after 2018

Buying new units:• Stay with the usual suppliers

easy to integrate, common software support,organized maintenance, shared experience,database

• Buy units that are commonly used (eg Wiener 0M22.0003)• Delivery times can be long

my last order took 5 months

Power supply sharing - summaryhttps://indico.cern.ch/event/354046/

See summary slides for proposal for sharing power suppliesIT + TT + OT + PS/SPD => TT + SciFi + CaloOptimum distribution of existing power suppliesBUT most sub-detectors have to purchase more units

Excellent database for orders, repairs, prices etc etc

LHCb Upgrade Infrastructure

- Electrical powering- Racks- Long distance optical fibres

Laurent Roy, CERN Upgrade infrastructure, 19-20 Feb 20159

Electrical installations- main additional power need (UX or Surface)? to be foreseen well in advance with EN/EL (previous slides from EL)

- Experiment equipment powered by same network of LHC (EXD)

can your systems live with power cuts?- glitches (µs ; often)- micro cut (ms-s ; few/year) rk: with LHC stop- AUG tests (1day/year)- switchboards, transformers maintenance (2-5days/2 years)

- Possibility to power systems with ‘secure’ powering (schema next slide) quantity of power limited : must be justified

- Possibility to install ‘repowering’ possibilities ex: for failure in the distribution, during AUG, maintenance
