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…

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
r2e mitigation project roles deliverables
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
monitoring calculations wg
Monitoring & Calculations WG
