Proposal for R&D activities to be submitted by interested institutes/groups to HL SGtemplate available from the HL SG web pageconcise but short

Evaluation by HL SGassign 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 Proposal GuidelinesR&D Proposal GuidelinesCriteria 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: Template for ProposalR&D: Template for ProposalL’High Luminosity WG ha preparato un Template per Proposte di R&D nel Framework di ATLAS:

QuickTime™ and aTIFF (LZW) decompressor

are needed to see this picture.


Common Activities with CMSCommon Activities with CMSDiscuss common R&D projects once concrete proposals have been submitted

or be even pro-active ... candidate joint R&D topics

CMOS processes (e.g. 0.13 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

ID Layout e Tipo di SensoriID 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 m2.(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 m2.Outer layer: µstrips, 2÷4 layers, 9 cm x 80 µm, 116 ÷ 327 m2.

Radiazione: pixel 1.6x1016 neqcm-2;

short strips 2x1015 neqcm-2;

µstrips 8x1014 neqcm-2.


R&D for TrackerR&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 collection3D detector (Pixel), high bias voltage (>1000 V), S/N (electronics)

Material engineeringn+-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.


Cost of UpgradeCost 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÷2007Pre-production: 2008÷2013 (15% of CORE)Production: 2011÷2015 (85% of CORE)

End of next week for first Numbers !


SommarioSommario 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&DNessuna 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
