1. Eric – (Slide#4) - itemized budget page – when are these items needed

1. Eric – (Slide#4) - itemized budget page – when are these items needed at LHC and what is their priority? (also ref: slide#20 of Oliver’s talk) (me) 2. Present the budget for FY 10 and FY 11 in a consistent format. (ref: Eric’s first talk, page#10). (Tom) 3. What is your plan for delivery of the rotatable collimators that is consistent with CERN’s schedule? (Tom) 4. Crab cavities – what is the plan? When will CERN assume leadership and issue technical and schedule requirements? (Rama) 5. How are you different from ILC-ART in e. Cloud? (Uli) 6. Resolution of HQ – when, how? (Gian. Luca and Peter) 7. Treat magnets as projects. Provide a resource-loaded schedule that culminates in one LHQ that meets CERN’s schedule. By when must you get the LHQ length specification from CERN to avoid compromising your schedule? (Gian. Luca and Peter) 8. What are the technical specifications you need from CERN for transition to full-length magnet construction and when do you need them? (Gian. Luca and Peter) E.

 The highest priority activities, which are tied to the CERN schedule are Rotatable

The highest priority activities, which are tied to the CERN schedule are Rotatable Collimator The first prototype is needed at CERN for installation end of 2010/beginning of 2011 for impedance and operational testing in the SPS. A second prototype or partial prototype will be needed for installation in the Hi. Rad. Mat facility at the end of 2011 for destructive testing. Devices beyond these will be part of a separate construction project Crab Cavities The exact plan is being worked out by CERN, but LARP’s role is most likely Development of a viable 400 MHz compact cavity design by 2012 A role in the construction of a prototype for installation in 2015/2016 E.

 E-cloud This is high priority to the extent that it informs the design

E-cloud This is high priority to the extent that it informs the design of a LLRF feedback system. The logical time for the system to be complete is when the Phase II/cryo collimation is installed in 2015/2016, however, it would be very important to develop and install the beam line hardware (ie kickers) in the SPS well before that, ideally for installation during the long 2012/2013 shutdown. PSB Studies LARP’s role (if any) in the PSB is still being defined, but the project is slated for completion during the 2015/2016 shutdown and anything we contribute would have to respect that time line. If we get involved with Profile Monitors, it would probably be useful to install a prototype in at least one of the PSB rings well before that (2012? ). E.
