The Radiation to Electronics (R2E) Project is responsible for the development and the implementation of mitigation actions to minimize the radiation induced failures in the electronics and thus to optimize the availability of the Large Hadron Collider (LHC). Significant shielding and relocation mitigation actions, coupled with a large number of equipment upgrades are being implemented during the first LHC Long Shutdown of 2013/2014 (LS1) in five LHC Points (Points 1, 4, 5, 7 and 8) and for electronics deployed in the remaining critical areas such as the LHC tunnel and adjacent RRs. This report first provides a brief summary of the radiation levels, the observed failures during Run-1, the LS1 R2E activities with particular focus on the expected improvements on the overall system failures. The last part of the report focuses on the qualification strategy, including radiation hardness assurance procedures and test facilities.
