5. CERN benjamin.todd@cern.ch Converter Control Electronics Questions to Equipment Experts 1/2 5 We need to know the inventory of electronics that need to be considered for radiation effects… 1) Remaining Inventory: What options are there for system relocation and what are the advantages/disadvantages? What equipment will remain in affected environments? Do you expect the amount of equipment exposed to radiation to be than Run1? Do you expect problems in the injectors? 2) New Inventory: What new developments are planned? What are they motivated by? [e.g. operational requirements, obsolescence requirements, …] We need to know whether cumulative effects due to radiation and electrical reliability are known… 3) Cumulative Effects: What are the predictions for cumulative radiation effects and electrical reliability? How is your long term supply of system components ensured? [e.g. WorldFIP]

6. CERN benjamin.todd@cern.ch Converter Control Electronics Questions to Equipment Experts 2/2 6 is access to the machine expected to be ? and will it be due to radiation? 4) Maintenance Expectations Do you expect the maintenance of your system to be ? Do you have a preventive maintenance strategy? Do you expect the ratio of access : remote interventions to be ? Is there common ground to develop a new system, designed specifically for the LHC machine radiation environment… 6) Signalling and Communications: At the interface to the machine, what are signal and bandwidth requirements? Communications mechanism between your system and controls? [Ethernet, WorldFip, …] what engineering effort would be needed to improve the system level availability? 5) Improving Availability What effort would be needed to make a 20% improvement?
