3. Urgent R2E Actions
Solution Finding / Clarifications & Decisions (follow-up):
P5 comparison of options (three ‘solutions’) and impact on planning/costs (Anne-Laure)
Open questions after CMS visit, see Anne-Laure/Markus (Anne-Laure)
Open questions for solution with gallery, see s following the discussion with Christoph and Martin (M. Gastal)
Gain between Bypass and UJ561 (cabling mainly),… -> Cost/Planningt (Anne-Laure)
How can the planning become shorter (e.g., cable installations in two shifts)
Shielding installation during xMasBreak: (Anne-Laure)
RRs: no due to risk and impact on power connections
UJ76: yes
UJ14/16: to be verified with consequences on adjacent inner triplet -> if no risk, then yes
Shielding Purchase: (Anne-Laure)
Table with shielding details per area, open questions, e.g., 2nd layer in US85 (Michael)
Reserve of 50% (of existing stock) – to be partly ‘compensated’ by new ‘reserve’ (Michael)
Installation of heavy blocks (>7t): Markus discussed with Serge and it might be feasible for the lower layers in the RRs, Serge will verify and keep us informed
Reserve in total amount: 10%
Status of complementary order (200 blocks) -> is this in the pipeline? (Michael)
Budget code to be defined for purchase, green light for divisional request (Roberto)

4. Urgent R2E Actions
Solution Finding / Clarifications & Decisions (follow-up):
P8 cable installation close to cryo installation: only those actions with no risk to operation to be performed (Anne-Laure)
Safe-Room P7/P5 solution finding (Markus)
Unlikely that shielding at P5 will be sufficient for operation until 2016
Safe-room situation needs to be reviewed (see workshop), also for P7
P7: VAC-racks -> Sylvain wanted to have a last iteration before the layout is frozen
P7: racks related to access -> details not clear (Sylvain), how much can be combined and could they also be switched off during operation (like access gates in P1/2/8)? (Anne-Laure)
P1 (UJ14/16) / P2 (UJ23) / P8 (UJ87) access gates: oral agreement on procedure -> to be clarified that we don’t relocate the access gate and it’s the equipment owner’s responsibility to assure the implementation of the procedure (Anne-Laure)
P8 shielding verification
Preliminary update of simulations shows that the shielding of the safe-room is coherent with the future shielding of the cryo-racks and towards the UW85 (Marco)
Additional simulations ongoing in order to verify comparison with monitors, as well as the long-term need/possibility of a second shielding layer

5. Start of Mid-Term Activities
SCL R&D (Amalia)
Started
Cable tests scheduled, in time for 2011 goal
WG will be created and keep direct contact with R2E
Power-Converter R&D (Yves)
R&D is in the medium-term plan, activity to be started now
Fellow will arrive or is already there
First steps:
First conceptual design studies
Radiation tests of existing power-converters
Aiming for a first conceptual design review in autumn 2010
Discussion with TE/EPC and F. Bordry to be organized (Markus)
H4IRRAD (Marco)
Generic calculations available
No showstopper so far
Next step: detailed layout, requirements (TE/EPC), RP issues
Aiming for radiation tests in February/March
Special RadWG scheduled for next week

8. Mandate R2E Project & Study Group
“The R2E Mitigation Project decides on action priorities, assures a mitigation plan within the LHC planning constraints and steers all R2E mitigation actions. Together with the R2E Study Group it assists LHC operations and equipment groups with expert knowledge and assessments of radiation-induced failures in electronics of the accelerator. The R2E mitigation project is steered by the R2E study group which directly reports to the LMC”
R2E Study Group Responsibilities:
Forum and steering meeting for R2E Mitigation Project
Development of a radiation policy for the accelerator sector
Direct link with related activities within the PH department
Advising and coordination role for all R2E related subjects and working groups
Availability of radiation test possibilities according to LHC requirements
R2E Mitigation Project Responsibilities:
Minimizing the risk of LHC failures caused by radiation effects on electronics
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
New radiation test facilities and possibilities within the requirements of the R2E project
Linked Activities:
Collimation upgrade at IR3 (IR7->3 Move)
SCL R&D
New radiation test facility in the PS East-Area

9. Monitoring & Mining WG Mandate:
Early monitoring around the LHC critical (R2E) areas
Comparison (“benchmarking”) with expected radiation levels
