  The level of flux of hadrons with en­ergy in the multi MeV range ex­pected from the col­li­sions at the LHC in­ter­ac­tion Points 1, 5 and 8 and from the col­li­ma­tion sys­tem at Point 7 will in­duce Sin­gle Event Er­rors (SEEs) in the stan­dard elec­tron­ics pre­sent in many of the con­trol equip­ment in­stalled in LHC un­der­ground. Fur­ther­more, a risk of SEEs in­duced by ther­mal neu­trons can­not be ex­cluded. Such events would per­turb the LHC op­er­a­tion, pos­si­bly lead­ing to a stop of the ma­chine. Main mit­i­ga­tion ac­tions will be im­ple­mented dur­ing the first LHC Long Shut­down of 2013/2014 (LS1) to re­duce the SEE oc­cur­rence. This paper sum­ma­rizes the mit­i­ga­tion mea­sures and their as­so­ci­ated fore­seen im­prove­ments in terms of SEEs. It pre­sents the or­ga­ni­za­tion process and as­so­ci­ated plan­ning high­light­ing the im­pacts with the over­all LHC LS1 plan­ning and the main con­cerns dur­ing im­ple­men­ta­tion.

  The CERN PS Booster (PSB) is presently un­der­go­ing an am­bi­tious con­sol­i­da­tion and up­grade pro­gram within the frame of the LHC In­jec­tors Up­grade (LIU) pro­ject. This pro­gram com­prises a new in­jec­tion scheme for H− ions from CERN’s new Linac4, the re­place­ment of the main RF sys­tems and an en­ergy up­grade of the PSB rings from 1.4 to 2.0 GeV which in­cludes the re­place­ment of the main mag­net power sup­ply as well as the up­grade of the ex­trac­tion equip­ment. This paper de­scribes the sta­tus and plans of this work pro­gram.
