  1. Meeting ALICE radiation tolerance. • Some reasons for this meeting: • A part very inner detectors (Pixels and SDD), ALICE has wide grey area; important decisions for the system depending on: • risk analysis (how much system failure can be tolerated) • economics (often parameter for ultimate decision of rad hard vs. COTS) • system architecture (system redundancy and quantization+location) • Electronics need to be validated for installation. • safe margins • performance/cost • evaluate weak areas and probability of shut down time • Never done ALICE survey before FF - August 30th 2004

  2. Meeting ALICE radiation tolerance. • Aims: • Status of COTS electronics in ALICE • tested • planned • “overlooked” • Regroup documents of tests already done by collaboration • improve ALICE database (knowledge) • stimulate commonalities (learn from others) • compare and conform conclusions (validate results) • Forum for discussion FF - August 30th 2004
