1. Link Board Upscope Frascati group Napoli group Warsaw group

2. Main Goal Design and produce an “updated version” of the present Link Board; to be used in the RPC upscope project and as spares in the RPC project. New design includes: – LV regulators – Critical component protections – Obsolete components replacement, if any – Any other improvements coming from the past experience. – back-compatibility 8/6/102Pigi Paolucci - CMS LB Review

3. Numbers and Schedule Numbers: – 150 upscope + 10% of spares – 100 spare for the present RPC project Schedule: – pre-production end of 2010 – production 2011 – Test, installation and commissioning 2011-2012 8/6/103Pigi Paolucci - CMS LB Review

4. Compatibility Full compatibility: – mechanical, electrical and firmware compatibility with the present system. – has to work in both new and old (protected) link box – possibility to have both protected and not protected boards in the same box 8/6/104Pigi Paolucci - CMS LB Review

5. Plan, schedule and budget Design in Italy (Warsaw, Napoli and Frascati) Board production in Italy Complete test setup at CERN (bulding 904) – Test under the Warsaw responsibility – Italian group will joint to learn about the test and the full system working Preproduction 2011, full production 2012 2011 budget will be discussed in Sept. at I.N.F.N. and assigned sub-judice to the RPC upscope approval and to a formal agreement with the Warsaw group. 8/6/105Pigi Paolucci - CMS LB Review

6. What new groups need Napoli group is composed by: physicist, electronic technicians and the electronic service supervisor – Napoli is studying the present project and the proposal made by Warsaw group to protect the link box with an external regulator. Frascati group is ready to contribute with elect. tech. What do we need more to begin: – List of broken components – Full set of schematics – Gerber files of the present LB PCB from Laaparenta/Warsaw – Meet Warsaw experts to learn and discuss about the new board (Napoli in September). Complete test setup at bulding 904 8/6/106Pigi Paolucci - CMS LB Review

7. Conclusions Now we have experience to design a “new” version of the link board. Two new groups (Napoli and Frascati) are joining LB upscope project. – Napoli experts are studying all the documentation and will be ready to meet and discuss the new design asap. Warsaw group will play a major role. Test and commissioning will be done at CERN under the Warsaw group supervision. INFN will discuss about the 2011 and 2012 budget in September. Budget request of about 400 K€ ? Pre-production at the end of 2010 8/6/10Pigi Paolucci - CMS LB Review7
