- What can be done at what temperature? (e.g. below 2.8 K low current tests), and when can we start the tests?
- Relaxed operation at reduced current (e.g. can we operate without cold compressors a magnet currents corresponding to 2 TeV)?
- Table for all steps and all circuits?
- Orbit correctors 60 / 120 A – what conditions? What needs to be watched by operators?
- Procedure: masking of int

- 450 GeV, 2 TeV and 5 .. 6 TeV: what circuits at what current? What can be left for later? (remember: it is always possible to bring in other circuits on the fly)
- How much time is required to commission for injection, for ~2 TeV, 4-6 TeV and 7 TeV? What could be gained? What circuits could be left out?
- When is tunnel access required? By whom? How to optimise it? What can be done without ac
