18. Consolidation of the LHC Quench Detection Systems MOTIVATION: Design of important part of electronics dating back to late ‘90, operating since 2007. Electronic components become successively obsolete. Original baseline assumed minimum number of spare parts and subsequent replacement of electronic boards (ca. 16000 boards in total) in function of the obsolesces of the components and/or their vulnerability to radiation induced phenomena Ongoing process After LS1 the main concerns are: vulnerability of the field-bus coupler chip of the MICROFIP type Obsolesce of several quench detection boards New DAQ systems based on the new radiation tolerant NanoFip are planned to be implemented Replacement of several board families is mandatory in order to eliminate obsolesce of the components and to improve their radiation tolerance 18 A.

30. Conclusions 30 MPE is proceeding as a function of allocated resources with the renovation of interlocks in the accelerator complex Priorities of renovation need to be agreed (to take into account physics priorities) and must be coherent with other renovation programmes (mainly TE-EPC and EN-EL) MPE proposal is to complete main proton/ion chain until end LS2 Experimental facilities until end LS3 Due to successive obsolesce of electronic components consolidation of the LHC magnet protection systems is a continuous process In case of the quench detection electronics it is not easy to decouple “pure consolidation” from R2E upgrades Bankruptcy and closure of premises of Russian manufacturer of unique 600A energy extraction breakers forces us to develop an alternative solution A.
