1 CMS ECAL Meeting Ecole Polytechnique 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 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 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.

4 CMS ECAL Meeting Ecole Polytechnique June 2005 A.B.Lodge - RAL 4 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? Cooling Bar assemblies? VFE Cards + LV Cards? FE & GOH Cards? TRLB & Cables? LV, HV, Fibre Optic Cables & Connectors? Patch Panels etc?

5 CMS ECAL Meeting Ecole Polytechnique June 2005 A.B.Lodge - RAL 5 ECAL End Cap ECAL EE Layout and Identification Proposal. Identification of the CMS ECAL - 2 End Caps. [1] D1, D2, D3 & D4? [2] +D1, +D2, -D3 & -D4? [3] +ZR, +ZL, -ZR & -ZL? [4] D1R, D1L, D2R & D2L? [5] Da, Db, Dc & Dd? Etc. Etc. Etc………………………. EE+ EE- EB Previously agreed on EE+ & EE-, to identify End Caps ? Centre LHC

6 CMS ECAL Meeting Ecole Polytechnique June 2005 A.B.Lodge - RAL 6 ECAL End Cap ECAL EE Layout and Identification Proposal. EE+F EE-N EB EE-F EE+N Previously agreed on EE+F, EE+N, EE-F & EE-N to identify End Cap Dee? Identification of the CMS ECAL End Cap - 4 Dees. Centre LHC

7 CMS ECAL Meeting Ecole Polytechnique June 2005 A.B.Lodge - RAL 7 ECAL End Cap ECAL EE Layout and Identification Proposal. SC - Crystal Numbers. Viewed from the Rear (Cooling Bar Side) looking through the Back-plate at the Top Right-hand Quadrant Previously agreed on to identify Crystal Numbers within each Super Crystal (SC)? 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.

8 CMS ECAL Meeting Ecole Polytechnique June 2005 A.B.Lodge - RAL 8 ECAL End Cap ECAL EE Layout and Identification Proposal. CMS ECAL End Caps - Crystal Numbers. Viewed from the Rear (Cooling Bar side) looking through the Back-plates Quad 1 Quad 2Quad 3 Quad 4 Previously agreed Quadrant Numbers?

9 CMS ECAL Meeting Ecole Polytechnique June 2005 A.B.Lodge - RAL 9 ECAL End Cap ECAL EE Layout and Identification Proposal. CMS ECAL End Caps - SC Interface Plate Types. Viewed from the Rear (Cooling Bar side) looking through the Back-plates Quad Quad Quad Quad Q uadrants 1 & 3 SC’s use Type 2 Interface Plates thus making them the same. Q uadrants 2 & 4 SC’s use Type 1 Interface Plates thus making them the same.

10 CMS ECAL Meeting Ecole Polytechnique 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

12 CMS ECAL Meeting Ecole Polytechnique June 2005 A.B.Lodge - RAL 12 ECAL End Cap ECAL EE Layout and Identification Proposal. What and How do we number on the ECAL EE? Service Ducts? EE Patch Panels? PP Connector Numbers? Mother Boards? EE+F & EE-N EE+N & EE-F FE Cards? EE+F & EE-N EE+N & EE-F LV Dist Modules? EE+F & EE-N EE+N & EE-F Token Ring Link Boards? EE+N & EE-F Cooling Bar Groups? EE+F & EE-N EE+N & EE-F

13 CMS ECAL Meeting Ecole Polytechnique June 2005 A.B.Lodge - RAL 13 ECAL End Cap ECAL EE Layout and Identification Proposal a b 23 Once we have agreed the Mapping/Numbering of : Trigger Tower Mapping ( Any 5). Data Sector Mapping. Trigger Sector Mapping. We could consider accessing the ECAL EE data in a similar way to this? Data Sector Number ?

14 CMS ECAL Meeting Ecole Polytechnique June 2005 A.B.Lodge - RAL 14 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.

15 CMS ECAL Meeting Ecole Polytechnique 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.

16 CMS ECAL Meeting Ecole Polytechnique June 2005 A.B.Lodge - RAL 16 ECAL End Cap ECAL EE Layout and Identification Proposal. EE+ Super Crystal Number 1 Trigger Tower Mapping. Viewed from the Rear (Cooling Bar Side) looking through the Back-plate at the Top Right-hand Quadrant It could be very useful to have individual SC Trigger Tower Maps readily available, particularly during the Building and Integration of the Dees? i.e. For the Testing of the Mapping.

17 CMS ECAL Meeting Ecole Polytechnique June 2005 A.B.Lodge - RAL 17 ECAL End Cap ECAL EE Layout and Identification Proposal. EE+ Super Crystal Number 5 Trigger Tower Mapping. Viewed from the Rear (Cooling Bar Side) looking through the Back-plate at the Top Right-hand Quadrant It could be very useful to have individual SC Trigger Tower Maps readily available, particularly during the Building and Integration of the Dees? i.e. For the Testing of the Mapping.
