3. RADWG Meeting October 2015 Salvatore Danzeca
RADWG Mandate
It provides support to the accelerator sector equipment groups for the assessment of radiation tolerance of electronic equipment to be installed in radiation exposed areas.
It is a forum for electronic engineers to discuss
design practices
radiation tests
radiation induced failures in the accelerators.
It coordinates radiation test campaigns on electronics inside and outside CERN
The RADWG assists the R2E Project leader for the evaluation of the technical aspects of the proposed mitigation actions with the representatives of the equipment groups

5. Equipment inventory and Radiation Monitoring
Know what there is in the tunnel and in the critical areas
Track the failures due to the radiation in the LHC and in the injector (collaboration with the AWG for the use of the AFT tool)
Suggest and foresee mitigation actions
Radiation testing coordination and supervision
Radiation Monitoring
Radiation levels in the entire accelerator (LHC and Injector) using RadMon, BLMs and passive dosimeters
Radiation levels to foresee the correct mitigation strategies
Radiation test requirements based on the measurements and calculation

6. New initiatives and developments
RADWG is the interface with all the ATS equipment groups
BE-CO in view of the CO3 initiative for the new CERN fieldbus foreseen for the LS3
BE-BI in view of the upgrade of the BPM frontend
TE-MPE splice protection system for HL and consolidation of existing hardware
TE-VSC in view of the new readout of the pressure sensors
BE-RF for the pickup amplifier for the transverse feedback in the PSB
TE-CRG in the use of a new architecture for their equipment
TE-EPC FGClite production

7. Radiation Test support and coordination
Users request driven support
Evaluate the possible radiation effects
With the input of the MCWG decide the target dose/fluences
Prepare the test setup
Carry out the tests
Report the results
From >130 components tested
FPGAs
ADCs
Mosfets
DAC
Transceiver
Etc..
2015: 42 components tested
2016: 52 components to be tested
18 already tested
All the reports are available on the EDMS:
8 PSI test slots in the 2016 (5 available)

System/Components Description
Phases
Phase 3
Radiation tests - Commercial Off the shelf components test
Phase 4
System radiation test
Final Summary
Installation Approval
Phase 5
Phase 6
Operation Follow up
Follow-up action of the 227th LMC Meeting
A document has to keep track of all the phases and the results
Proposal: A part in the ECR should be added to keep into account the RHA approval
