Questions to Equipment Experts 1/2We 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]

Questions to Equipment Experts 2/2is 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 <, = or >?
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?
