Life Cycle Management and Reliability Analysis of Controls Hardware Using Operational Data From EAM / Fortescue, Eve (CERN) ; Kozsar, Ioan (CERN) ; Schramm, Volker (Stuttgart U.)
The use of operational data from Enterprise Asset Management(EAM) systems has become an increasingly popular approach for conducting reliability analysis of industrial equipment. This paper presents a case study of how EAM data was used to analyse the reliability of CERN’s standard controls hardware, deployed and maintained by the Controls Electronics and Mechatronics group.

Run 2 Overview of the LHC Beam Instrumentation / Krupa, M (CERN) ; Alves, D (CERN) ; Gasior, M (CERN) ; Kral, J (CERN) ; Levens, T (CERN) ; Schramm, V (CERN) ; Wendt, M (CERN) ; Zamantzas, C (CERN)
This papers reviews the implemented improvements, operational experience, and performance reach of the major LHC Beam Instrumentation systems, excluding transverse beam profile diagnostics, throughout the LHC Run 2. The major hardware and software changes since the Long Shutdown 1 (LS1) are highlighted and the main actions addressing the remaining open issues during the Long Shutdown 2 (LS2) are listed. [...]

Combined Testing And Validation Strategy For The New LHC Blm Processing Module / Schramm, V (CERN) ; Saccani, M (CERN) ; Viganò, W (CERN) ; Bertsche, B (Stuttgart U.)
A comprehensive strategy to test a new digital acquisition board has been implemented by the Beam Instrumentation Group of the European Organization for Nuclear Research (CERN) as part of a wider methodology for the design, production, test, and operation of high dependability electronic systems. This includes test benches for component and functional testing during production, as well as for validation and burn-in upon reception. [...]
