1. R2E Mitigation Project Status Report 2 nd R2E Committee Meeting 20.01.20111R2E Project Report

2. Follow-Ups R2E Mandate: not required for Chamonix presentation, propose however that we reorganize the website according to committee and project (according to current understanding) Safe-Rooms: phased approach agreed upon -> see last slide “Benchmarking”: -> see report from Marco Layout drawings: 90% ready, whom to contact to include them into the official repository Memorandum for P5: update from RP + safe room discussion to be included -> rather a report than a memorandum? 20.01.20112R2E Project Report

3. R2E Highlights (Dec, Jan) Detailed Analysis of 2010 Operation – RadMon, BLM & Ratios – TLD Results for low-rad readings – Analysis of losses/luminosities/intensities Shielding & Integration – P5 close to baseline (few issues: e.g., support structure) – Opening of shielding tender (21.1.) – Shielding update for US85 – P1 issue through UX/UL wall Power-Converter R&D – Project advancing (conceptual studies) – 1 st course on radiation hard developments held (for TE/EPC) – Extensive component test campaign for 2011 (test request?) – Collaboration set up with University of Montpellier & TRAD Safe-Rooms – phased approach developed together with EN/EL (waiting for safety input for phase-I, EN/EL for phase-II/III) – Critical point for baseline in P5 and P7 Benchmarking (good agreements with FLUKA) – UX85/US85 – IR7 + … 20.01.20113R2E Project Report Calibration, Calibration, Calibration Priority: Ready for 2012

4. Safe-Room Update phased relocation approach which foresees: a first relocation of the most sensitive control equipment (racks: EYU, EYC and EYP) 230/48V supply from the surface (safety light + remaining 48V equipments) AUG verification and options (surface or other location) relocation of remaining (so-far judged low- risk) equipment, especially in case new (sensitive) components have to replace the existing equipment 20.01.20114R2E Project Report Reduce Risk Improve If Required Radiation Tests in H4

5. Further Failure Rate 2010 Radiation Level Analysis Update of Estimate (scary) Interesting Loss balance not available (so far) by OP Many issues with quality of logging (and signals) -> difficult for anlaysis Aiming for 50ns in 2012 (~100MJ or 1/2nom @4TeV) 20.01.20115R2E Project Report See Chamonix Slides
