摘要：

The actions taken during the first years of the Radiation to Electronics (R2E) Mitigation Project [1] enabled to drastically reduce the rate of Single Event Errors on radiation-sensitive electronic equipment installed in the LHC underground areas. Shielding and relocation activities, performed during the first Long Shutdown (LS1) in 2013/2014, will allow the resolution of the present issues concerning UJs of Points 1, 5, 7 and the cavern of Point 8. The parallel development of radiation tolerant power converters will address the remaining concerns for equipment in the RRs. Similarly R&D on super-conducting links will address the relocation of equipment away from RRs and further exposed UJs. Radiation levels in areas where luminosity is the source are under control. The questions yet remaining are related to the evolution of the beam-gas source term in the arc and dispersion suppressor (DS) region, and to the evolution of losses at the betatron and momentum insertion regions. 2012 operation will enable these points to be investigated; this will be used for a complete forecast of radiation levels and projected failures after operation is resumed in 2014/15.
