• What else do we need to know to definitively adopt Finemet cavities? When the decision can be made?
• What is left to demonstrate with the digital LLRF (e.g. synchronization before transfer, different intensity ranges, test more than one ring)?
• Are RF by-passes an issue?
• Can some of the new hardware for the transverse damper tested this year?
