- What happens before powering tests after cooldown
- Main issues that slowed us down
- ELQA: Continue as for sector 45? Further optimisation of the strategy?
- What has been done during the powering tests? During what time? By whom? Efficiency?
- How to ensure minimization of re-commissioning 45 and to secure what has been achieved?

- Partial heater firing if switches do not open – yes/no?
- Access to the tunnel for 600 A extraction switches, can be optimised?
- Firing heaters without current in the magnet circuit – Why? EMC due to other tests?

- 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...
