  1. Project / Study Group / RadWG R2E Mitigation Project: • Responsible of development and implementation of long-term R2E mitigation plan for the LHC accelerator • Project decisions are taken by the project leader, strategic aspects are discussed in the committee (e.g., long-term solutions and requirements globally affecting the A&T sector), • Reports to the LMC R2E Study Group -> R2E Committee: • Long-term R2E goals aside the R2E Mitigation Project and with a longer mandate • CERN R2E Policy (A&T Sector) • R2E aspects also at other accelerators (present and future) and respective needs • Steering committee for strategic discussions concerning the R2E project • R2E Project meetings as membership strongly overlaps and only one meeting is kept • R2E project leader reports on the project status and might require endorsement of strategic decisions • Reports to the LMC Radiation Working Group: • Coordinates radiation test campaigns (CERN internal and external) • Forum for equipment owners (in the A&T sector) to discuss technical aspects related to radiation damage to electronics • currently focused on SEEs and electronics (as support for the R2E Project) • other aspects: cumulative damage, radiation damage to materials (e.g., cables), etc…

  3. Mandate R2E Project & Committee “The R2E Committee assists the A&T sector with expert knowledge on radiation damage to electronics and all related aspects. It steers all R2E related working groups and shall define a global electronics policy. It reports to the LMC” R2E Committee Responsibilities & Activities: • Development of a radiation policy for the accelerator sector (LHC, injectors and new projects) • Direct link with related R2E activities within the PH department • Advising and coordination role for all R2E related subjects and the Radiation Working Group • Radiation test facilities beyond the need of the R2E mitigation project • Discussion forum for the R2E project, committee meetings are at the same time project meetings “The R2E Mitigation Project decides on action priorities, assures a mitigation plan within the LHC planning constraints and steers all R2E mitigation actions. The project leader reports to the LMC.” R2E Mitigation Project Responsibilities & Activities: • Minimizing the risk of LHC failures caused by radiation effects on electronics installed in critical LHC areas • Development and implementation of a R2E mitigation plan coherent with the LHC schedule • Evaluation based on radiation monitoring and calculations • Study of patch-solutions and radiation tolerant developments • Support and review of R&D for radiation tolerant power-converters • Study, feasibility analysis and final proposal of long-term mitigation solution • Budget planning, steering and optimization of all mitigation actions • Radiation test facilities within the requirements of the R2E project (CNRAD, H4IRRAD) Linked Activities: • Collimation upgrade at IR3 (IR7->3 Move) • Superconducting Links R&D • New radiation test facility in the PS East-Area

  4. R2E Mitigation Project Roles & Deliverables Roles: • Assurance of global mitigation actions and their implementation within the LHC planning • Long-term solution for power-converters & evaluation of options • Support for all R2E activities linked to the R2E mitigation project and assurance of availability of requirements (e.g., test areas) • Project planning and coordination Deliverables: • Mitigation Plan & Required Documentation • Evaluation of Radiation Levels & Consequences • Decision on best long-term mitigation option • Implementation and review of mitigation actions • Availability of radiation facilities and radiation test support • Budget/resources/timing details & reporting

  5. Monitoring & Calculations WG Mandate: • Early monitoring around the LHC critical (R2E) areas • Comparison (“benchmarking”) with expected radiation levels • Coordination of required R2E Monte-Carlo calculations • Improvements for the combined monitoring tool & related issues • Possible required improvements for monitor locations & numbers • Extrapolation towards nominal LHC operation • Development of a standardized reporting of radiation levels Members: • RadMons: D.
