ECAL End Cap ECAL EE Layout and Identification Proposal. The talk is mostly ideas and initial concepts in relationship to numbering and labelling of component parts which go to make the CMS ECAL EE: • Nothing is set in concrete. • Things can be changed (for good reason). • Incorrect understanding? • Better ideas? • Less work or cost? • Etc. etc……. etc? We should also keep in mind ‘Time Scale’ and ‘Level of Work’. CMS ECAL Meeting Ecole Polytechnique. 29 - 30 June 2005 A. B. Lodge - RAL 2

ECAL End Cap ECAL EE Layout and Identification Proposal. CMS ECAL EE Identification Ideas? When deciding on a scheme we should: • • • Not just Crystals and Super Crystals Numbers. Keep it simple, when possible. Clear and concise. Unambiguous. Minimise the level of documentation. Minimise the possibility of mistakes during, the definition, manufacture, build and Integration. CMS ECAL Meeting Ecole Polytechnique. 29 - 30 June 2005 A. B. Lodge - RAL 3

ECAL End Cap ECAL EE Layout and Identification Proposal. What and How do we number on the CMS ECAL EE? • • • End Caps? Dees? SCs? Crystals & VPTs? HV Cards & Umbilical? Mother Cards?

ECAL End Cap ECAL EE Layout and Identification Proposal. CMS ECAL EE SC Types: • Initially would have liked all SCs to be the same (apart from their unique Positional Spacer). The reality is: • We need 2 types of interface plate (i. e. 2 types of SC). • Trigger Tower Mapping to Electronics? Helen Madj • Possibly Crystal sorting? • Possibly VPT sorting?

ECAL End Cap ECAL EE Layout and Identification Proposal. CMS ECAL EE Identification Ideas? I believe by using: • • Relatively simple layout diagrams. Trigger mapping diagrams. Sector mapping miagrams. Individual SC Connection Spreadsheet. Individual TRLB Mapping Diagrams. LV Distribution Mapping Diagrams. Etc………. Will minimise the possibility of mistakes during, the definition, manufacture, build and Integration of the CMS ECAL EE. CMS ECAL Meeting Ecole Polytechnique. 29 - 30 June 2005 A. B. Lodge - RAL 14

ECAL End Cap ECAL EE Layout and Identification Proposal. Conclusions: To continue to make progress with the complex and detailed Mapping of the EE Trigger Towers to VFE Electronics, also the FE (GOH) Fibre Optic Mapping to the EE Patch Panels Connectors we need to agree : • A detailed Trigger Tower Map? • The Trigger and Data Sector Mapping? • And finally the Trigger/Data Sector numbering and orientation.
