1. CMS ECAL Meeting Ecole Polytechnique. 29 - 30 June 2005 A.B.Lodge - RAL 1 ECAL End Cap CMS ECAL End Cap Trigger Meeting. Meeting held 29 th - 30 th June 2005 Paris - Ecole Polytechnique. Prepared by A.B.Lodge. ECAL EE Layout and Identification Proposal.

2. CMS ECAL Meeting Ecole Polytechnique. 29 - 30 June 2005 A.B.Lodge - RAL 2 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 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’.

3. CMS ECAL Meeting Ecole Polytechnique. 29 - 30 June 2005 A.B.Lodge - RAL 3 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.

A Super Crystal consists of a 5 * 5 matrix of PbWO 4 Crystals contain and supported by a Carbon Fibre Alveolar. It is made unique by attaching it to the Back - Plate using a unique Aluminium Positional Spacer.

10. CMS ECAL Meeting Ecole Polytechnique. 29 - 30 June 2005 A.B.Lodge - RAL 10 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? Possibly Crystal sorting? Possibly VPT sorting? HelenMadj

LV Distribution Mapping Diagrams. Etc………. Will minimise the possibility of mistakes during, the definition, manufacture, build and Integration of the CMS ECAL EE.

15. CMS ECAL Meeting Ecole Polytechnique. 29 - 30 June 2005 A.B.Lodge - RAL 15 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.
