R&D per ATLAS G. Darbo - INFN / Genova Frascati, 24 Novembre Procedure for R&D  HiLumi WEB R&D for upgrade must follow procedures defined on the HiLumi WEB page

R&D per ATLAS G. Darbo - INFN / Genova Frascati, 24 Novembre How to Start R&D in the ATLAS Framework  Proposal for R&D activities to be submitted by interested institutes/groups to HL SG  template available from the HL SG web page  concise but short  Evaluation by HL SG  assign 1-2 referees (incl. experts from systems)  project/system leaders consulted  Circulation to Collaboration Board (CB)  Second evaluation by HL SG  Recommendation by HL SG to Executive Board (EB)  See detailed text (approved July 2005 by CB)

R&D per ATLAS G. Darbo - INFN / Genova Frascati, 24 Novembre R&D Proposal Guidelines Criteria for evaluation  formal aspects  clear and precise presentation of proposal  quantitative estimates of timescales and resources  well defined milestones for the R&D activities  scientific aspects  R&D topic fits into ATLAS activity structure  activity respects the various constraints etc.  proposed activity fits into foreseen time schedule  resources foreseen match schedule  funding aspects  critical mass for activity existing / expected Template for R&D proposal  available at the HL web page:

R&D per ATLAS G. Darbo - INFN / Genova Frascati, 24 Novembre R&D: Template for Proposal L’High Luminosity WG ha preparato un Template per Proposte di R&D nel Framework di ATLAS:  DES/ATLAS_RD_template.doc DES/ATLAS_RD_template.doc

R&D per ATLAS G. Darbo - INFN / Genova Frascati, 24 Novembre Common Activities with CMS Discuss common R&D projects  once concrete proposals have been submitted  or be even pro-active...  candidate joint R&D topics  CMOS processes (e.g μm), optical links,... Discuss timescale to implement (major) upgrade  when to replace the tracking detector  likely to require at least a one year shutdown  relation to major machine changes (interaction region) Discuss scope and size of upgrade  arrive at common point-of-view wrt machine  e.g. optimization of electronic replacement costs vs. RF replacement costs

R&D per ATLAS G. Darbo - INFN / Genova Frascati, 24 Novembre PBS for R&D

R&D per ATLAS G. Darbo - INFN / Genova Frascati, 24 Novembre ID Layout e Tipo di Sensori  Numero di layers 8÷11 (probabilmente 10):  Inner layer: Pixel, 3÷4 layers, 300÷400 µm x 50 µm, 2.9÷3.7 m 2. (forse pixel più piccoli per il b-layer)  Middle layer: short strips o stripxel, 3÷4 layers, 3.5 cm x 80 µm, 21÷27 m 2.  Outer layer: µstrips, 2÷4 layers, 9 cm x 80 µm, 116 ÷ 327 m 2.  Radiazione:  pixel 1.6x10 16 n eq cm -2 ;  short strips 2x10 15 n eq cm -2 ;  µstrips 8x10 14 n eq cm -2.

R&D per ATLAS G. Darbo - INFN / Genova Frascati, 24 Novembre R&D for Tracker  No R&D Submitted till now.  R&D topics (as discussed at the ATLAS Tracker Upgrade Workshop in Genova):  R&D - Pixels rad-hard sensors, 0.13 µm electronics (FE, Controller/Optolink), power scheme (serial/DC-DC converter), cooling.  R&D - Short strips module concept, faster electronics, power, cooling.  R&D - µstrips faster electronics, power, cooling, cost.  Charge collection 3D detector (Pixel), high bias voltage (>1000 V), S/N (electronics)  Material engineering n + -in-n (as for today pixel), p-type floating zone FZ (50% cheaper, need single side processing) for µstrips, High resistivity Magnetic Czochralski (MCz) silicon, epitaxial silicon (p and n-type).  We are also investigating to have a Tracker Electronic Workshop of 2 days late next spring. It should be an ATLAS/CMS workshop and its aim is to boost specific and common R&D.

R&D per ATLAS G. Darbo - INFN / Genova Frascati, 24 Novembre Cost of Upgrade  The High Luminosity WG is preparing a document (2 pages) with a crude estimation of the costs for Upgrade:  Document will be ready in draft version by end of November.  This document can be used as a first evaluation by INFN to prepare the “Road Map”  Most of the cost will be the Tracker and it will also depend on the “Production Model” for Module assembly (test should be stay in the labs):  Industry vs. Participant Laboratories. (this can weight 2 MSFr for Pixel only)  In addition to R&D cost we have to consider NRE costs (1 set of mask for 0.13 µm technology costs 660k$ !)  Cost Profile:  Basic R&D: 2005÷2007  Pre-production: 2008÷2013 (15% of CORE)  Production: 2011÷2015 (85% of CORE) End of next week for first Numbers !

R&D per ATLAS G. Darbo - INFN / Genova Frascati, 24 Novembre Sommario  Gli R&D del Tracker (e di ATLAS) sono coordinati dall’HL WG  CB  EB di ATLAS  Esiste un PBS (Project Breakdown Structure) degli argomenti di possibili R&D  Esiste un template per la sottomissione dei progetti di R&D  Nessuna richiesta ad oggi  La stima dei costi dell’Upgarde sono in fase di valutazione da parte dell’HL WG e saranno disponibili per un’eventuale discussione al di fuori del working group per la fine di Novembre
