M. Letheren, LECC 1 June 2001; Status of RD49 and COTS; objectives of one day review1 Status of RD49 and COTS and objectives of a one-day review RD49 - Study of the radiation tolerance of ICs for LHC. (LEB 1997) COTS - Project to coordinate the selection, evaluation & procurement of Commercial-Off-The-Shelf (COTS) components for use in the radiation environments of the LHC. (LEB 1999)

M. Letheren, LECC 1 June 2001; Status of RD49 and COTS; objectives of one day review2 RD49 motivation + objectives Situation in 1997: Rad-hard ASIC technologies were: Expensive (small-volume, hi-rel military & space markets). Disappearing rapidly (end of cold war). Not qualified for LHC radiation levels (except DMILL). Unreliable (low yields, run-to-run variability). RD49 was launched to: Study deep submicron (DSM) approach for rad-tol ASICs. Select a single DSM technology for LHC. Develop demonstrators of LHC-type ASICs.

M. Letheren, LECC 1 June 2001; Status of RD49 and COTS; objectives of one day review3 RD49 - achievements Proved rad-tol design method. Extreme TID hardness, good SEE immunity. IBM 0.25  m CMOS process selected. Frame Contract for LHC (12 MCHF, until Q4 2003). Export license (USA, EU, Canada, Japan). Support by CERN & RAL (Design kit, library, MPW). LHC baseline designs ( from RD49 demonstrators) 10 authorized “design centres”. (CERN, RAL, INFN, IN2P3, PSI, Heidelberg, FNAL, LBL, UPenn, Columbia) Pixels, APV25, Pascal, GOL, and many more.

M. Letheren, LECC 1 June 2001; Status of RD49 and COTS; objectives of one day review4 RD49 - what next ? RD49 completed. all R&D objectives surpassed. New common project: Support 0.25  m technology access for LHC. Prepare for obsolescence of 0.25  m process. R&D for future experiments?

M. Letheren, LECC 1 June 2001; Status of RD49 and COTS; objectives of one day review5 RD49 review – objectives (1) Review support of IBM 0.25  m process: Design kit and rad-tolerant library Rad-soft commercial library Technical and commercial interface to IBM Organization of Multi-Project Wafers (MPWs) Legal issues (restrictions, export licences, etc.) Manpower for support

M. Letheren, LECC 1 June 2001; Status of RD49 and COTS; objectives of one day review6 RD49 review – objectives (2) Review requirements of expts Baseline LHC programmes: Volumes, procurement schedules, etc. LHC luminosity upgrade & other expts Extreme rad-hardness (e.g. NA60 beamscope) => cryogenic strips --> cryogenic electronics. Low-cost, large-area pad/pixel detectors => R&D on monolithic architectures. (integrating detector on electronics wafer)

M. Letheren, LECC 1 June 2001; Status of RD49 and COTS; objectives of one day review7 RD49 review – objectives (3) Scenarios for handling future obsolescence of IBM 0.25  m process: IBM frame contract is valid until Q Extensions negotiable (in principle) but: Uncertain life-time of 0.25  m process. HEP is a very small “customer” (or disturbance?) LHC procurement strategies (Buy and store spares. How many?) Set up rad-tol support for a next-generation technology. Criteria for selecting and evaluating next technology. Estimate required resources (manpower, CAE, test equipment). Review challenges and define demonstrators (e.g. large dynamic-range analog circuits in 1 volt technology) Lead time to support a new technology ~ 3 years ?

M. Letheren, LECC 1 June 2001; Status of RD49 and COTS; objectives of one day review8 COTS motivation + objectives Before ~1999: COTS risks were poorly understood: No risk management strategies. No (or inappropriate) qualification procedures. Preparing production with unqualified components and sub-systems. COTS common project (LEB 1999): Raise awareness of COTS risks. Coordinate effort for selection, qualification, procurement. => Created network:Faccio (RD49), Dentan (Atlas), Stefanini (CMS), Christiansen (LHCb), Formenti (Alice), Rausch (machine)

M. Letheren, LECC 1 June 2001; Status of RD49 and COTS; objectives of one day review9 COTS achievements Raising awareness COTS workshops; external consultants (Space). One-week Technical Training course. SEE threshold & cross-section measurements made => predictions of SEE rates in ATLAS/CMS. Coordination and sharing of effort ATLAS policy on radiation-tolerant electronics. CMS COTS test protocol (muon boards). Elec. System Reviews consider COTS. Coordination of irradiation runs (Cyclone, Prospero, Pagure). CERN COTS database (sharing test results). “Missing” COTS (voltage regulators) => common spec & development with industry

M. Letheren, LECC 1 June 2001; Status of RD49 and COTS; objectives of one day review10 COTS review - objectives Review and summarize: Qualification procedures. Irradiation facilities. COTS database (CERN and external) Procurement procedures (e.g. qualified lots). Review status of Voltage Regulators: Prototype performance Specs. Versus requirements Required volumes Procurement plans
