1. Cables Ian Crotty 8 May 2012 Cables for the RE4 Upscope in CMS News. The HV cables are in the Integration DB (INB/904) The Hv order is confirmed. Need delivery times for small quantities and total. HCaL have made input to QC tests. HV YE1 PP was checked for as built. The layout in USC will be done with Shoaib. Signal Negociations with Cavitech indicate original price maintained. Connector & ancillaries given to JFP. Need originals of Excel & Autocad. Still problem with total cable +Fibre length to Far X2

2. Cables Ian Crotty 8 May 2012 News Continued Rack cabling. I have latest “as built” doc from S. Lusin and will talk this week. Trigger cables Confirm what cables to be made. Establish who will produce. Present a full list of cables to integration asap. Production schedule to be established.

4. Cables Ian Crotty 8 May 2012 The Range of Cables Chamber cables HV cables from patch panel(YE1) to chamber LV cables from Caen 3009 (Racks) to chamber DCS cables from Link Board Crate to chamber Signal (LVDS) from Chamber to Link Board crate (LBB) Temperature sensors. Inter rack cabling LV (48V) cables from Mao(ACDC) to Easy Crate, Caen 3009 (x4) LV 3 phase from rear of rack to ACDC. (x2)? Caen bus communication cables(x4) from Mao to Easy crate? USC/UXC cabling Branch Controller (LV and Comm.) to YE1 PP and YE1PP to Mao. HV, USC/UXC connection is there, had been installed for RE1/1

5. Cables Ian Crotty 8 May 2012 Trigger Cables Trigger Cables (& Fibres) 12 new LBB crates each with 4 LV cables (2.5V & 3.3V) from the Caen 3016. The cable is in the ISR. The signal fibres from the LBB to the USC are already in place, only 50%used. New “Double” fibres (80) are needed from each tower thru’ the Mini Cable Chains to YE1 Fibre PP.? TTC fibres on YE3. Ethernet cable ring on each yoke. The new LBB will not need the add on regulator with its associated cabling. The Polish expert is Krzysztof

6. Signal Cable RE+4 In Racks on X2 there is a length problem wrt RE3, that will require rerouting. Heat Exchangers will be added

Signal Cables Signal cables /LBB Crate6x6x2 [RE4/2&RE4/3]72 Signal cables Total [RE-4 & RE+4]864 DCS cables1 x 144144 Industry was used for the previous production which included the QA up to the skew test. This approach is required here given the manual nature of the job. The twisted pair cable has no laminated zones and so each strand of each pair has to be placed individually with no errors. I propose to contact the company for a quote, in terms of delay and cost. The company estimates 2 months. The skew test could be done by the same industry or in-house, specific simple to use equipment is required as was built for the previous production. 7

8. Cables Ian Crotty 8 May 2012 HV cable production HV cable from Chamber to YE1 PP144 pieces The connector assembly is very delicate and intricate, and so should be followed in-house. The testing will be done at 15kV (as before), this time with current, for some hours. Clearly all failures are identified and the connector redone, numerous failures are to be expected. The person should an expert available for 2 months. Spares for repairs on the yoke and diagnostics (x10)

The number of cables of any one type, involved here, is small and so should be done in- house. 2 month of a cabling technician.

10. Cables Ian Crotty 8 May 2012 Questions and Conclusions No new cable types so no new CERN approvals required. 904 Integration office must confirm integration, cable path & length wrt piping, Mini cable chain etc The cable space allocated in 904 will be used including the space ISR. Signal cables made with previous company near Neuchatel. QA & QC procedures must be established for each cable type. All cable types are in drum form, require connectorising, (including procurement of connectors) Costing will come when full component list is established. See below. Full breakdown of cabling needs is being built here: “http://rpc-cms-re4-upscope.web.cern.ch/rpc-cms- re4upscope/RPC/Services/CableOverView/ file name “CablesUXCUSCRE4.xlsx” Cables should be ready for installation end 2012 This talk can be seen at; http://rpc-cms-re4-upscope.web.cern.ch/rpc-cms-re4- upscope/RPC/Services/CableOverView/CablesRE416April2012V3
