Description
TThis meeting will examine the scope of the pre-project CFS work, the schedule, and necessary resources. The detector hall concept at the proposed site, and the impact of energy phasing will also be addressed. The pre-project CFS timeline will likely drive many aspects of the accelerator design work in the next few years thus it is important to understand these constraints. In order to derive a site dependent ILC design and address long lead-time CFS activities then we need to assess what design information needs to be available to the CFS group and when. The ILC technical design in the TDR relied on a generic site description which is inadequate to proceed much further in the site specific design.
There are 4 sessions per day and should last ~90 minutes each. Talks should be ~45 minutes (30 mins if 2 talks in that session) which leaves a similar amount of time for discussions. The Chairs will work with the speakers to ensure the talks address the topics. As we generally only have one named speaker per session it will be important that their presentations “provoke discussion”. One assumes this will be achieved by people presenting some minimum list of open issues and questions that we need to discuss. The session annotations hopefully give some sense of this.

The CFS pre-project work scope will determine the readiness for a construction project hence we need to understand the elements of the work scope and their individual schedules. Can any items be delayed with compromising the effort ? Can the 5-year estimate for this work be shortened in any way ? Since non trivial funding will be needed to complete this work then this implies some kind of budget before the anticipated GO-NOGO decision in 2016. How much money is needed and when, if we try and minimise a pre-project request.

ADI Support of CFS
There remains” loose ends” in several systems in regard to CFS requirements. Ascertaining these issues will help determine the systems groups work scope and remaining CFS uncertainty.

Technology Support & CFS Impact
This session will examine issues related to the tunnel and access-tunnel X-sections and input penetration layout. Is the generic tunnel layout including accessibility and safety now stable?

Hitoshi Hayano(KEK)

Cryomodule & Waveguide installation, LHe inventory control, Radiation shielding, Safety
Do we understand the Detector design well enough to determine the CFS Detector Hall requirements ? Is there risk that significant Detector changes could still remain ? Can we identify the major technical cost drivers arising from the Detectors in terms of the CFS, including comparisons of effects with vertical shaft and horizontal access?

Can we conclude the horizontal – vertical access debate ( at least conceptually) ? Hybrid model – positives/negatives. When do we need to resolve this? What needs to be done in the near term to facilitate this decision?

Energy Phasing
The proposal to implement the project in stages has implications for the CFS approach and scope. What are these features (transfer lines, cryogenics, installation, storage, test facilities ……)? There may be a request for energies in excess of 500 GeV as part of the project baseline. How do we approach this?

Site Infrastructure
Further information will be required soon on the outside-the-TDR site needs (power, water, roads etc….). How well do we know these requirements ? Are there any significant energy efficiency opportunities ? Power reduction on demand ?

The CFS pre-project work scope will need to have aspects of the accelerator design to be finalised at certain points in the timeline. We need to define when this ADI input is needed and what aspects needed to be defined. What near-term aspects of the CFS work will need to be addressed and what resources will be available.

Wrap-Up
We will use this session to document the conclusions and map out a plan for the next few years: the LCC phase. We will also discuss how we may well prepare for the AWLC14, to be held at Fermilab in May.
