Specific to this ACE meeting
The 5th ACE meeting will focus on the technical progress towards the CDR design and the status of the R&D program needed to demonstrate CLIC feasibility in support of the CDR.
The ACE is asked to comment on:
i) the layout and schedule for the CDR
ii) the schedule of the CLIC feasibility demonstrations and timing of the CDR
iii) the technical and/or design status of the following subjects drawn from the “list of CLIC critical issues”:
1) RF structures (MB + DB)
2) DB + MB generation (phase, intensity, energy stability)
3) Two Beam Acceleration
5) Preservation of ultra low emittances, highest luminosity

4th ACE meeting (02-04/09/08)
Specific Mandate: Focused on progress and plans for critical R&D supporting the CDR and beyond
The Committee is invited to review, assess and comment on these plans. In specific, the committee is asked to evaluate:
a prioritized list of the most relevant CLIC technical issues and their classification by feasibility, performance and cost impact.
the R&D status and plans to address the critical issues
the R&D program and the schedule to complete a CLIC Feasibility Demonstration as well as a Conceptual Design Report
A first proposal of technical objectives and planning for the Technical Design Phase in the years 2011 - 2015
ACE report: Report not (yet?) available
Recommendations to CLIC team:
Extensive detail behind each topics providing greater
detail of feasibility demonstration for 2010 and future
studies in early TDR period (2010-2012)
CTC list did not prioritize between programs
Believe that this may be necessary
J.P.Delahaye
Concerned that a large task to complete by 2010
Focus on CLIC-specific items as much as possible
Consider CDR / feasibility schedule carefully
Plan to engage international community in extended workshop post-CDR
All issues addressed till 03/02 pm:
CDR schedule and organisation: H.Schmickler
CLIC feasibility summary: JPD
1 H00 discussion on feasibility benchmark and expected level of accomplishment by end 2010
J.P.Delahaye
Aggressive structure program
PETS HOM benchmark studies
Injector issues and stability …
Two beam Acceleration & CTF3 (02/02 pm)
TBTS high priority for key two beam acceleration demonstration
Increased effort for experimental program
Develop schedule & priorities
Significant extrapolations
Subsystems issues (Inj., DR, RTML, ML, BDS)
Stabilisation
Mobilize the CTF3 collaboration for increased participation in operating the test facility and in CDR
J.P.Delahaye
Possible for a strong CERN program (3 ~ 4x present)
Consideration of pre-construction demonstrations
~700 meters of TBA linac
Challenging to even demonstrate CLIC drive beam hardware and beam dynamics
100 A and 240 ns drive beam
Must balance between completing broad design and demonstrating near-final drive beam linac hardware
Ongoing discussion that should engage international community pre- and post-CDR

CLIC / ILC Joint Working Group on General Accelerator issues
ILCSC has approved formation of two CLIC/ILC General Issues working groups by the two parties (one on Accelerators and one on Detectors) with the following mandate:
Promoting the Linear Collider
Identifying synergies to enable the design concepts of ILC and CLIC to be prepared efficiently
Discussing detailed plans for the ILC and CLIC efforts, in order to identify common issues regarding siting, technical issues and project planning.
Discussing issues that will be part of each project implementation plan
Identifying points of comparison between the two approaches .
The conclusions of the working group will be reported to the ILCSC and CLIC Collaboration Board with a goal to producing a joint document.

TDR task force chaired by R.Corsini presented @ Advisory Committee (May09):
J.P.Delahaye
Start from needs and not from (potentially) available budget / resources
Begin with list of activities and feasibility / critical items
Determine where we will likely stand in 2010.
Define a logical extension of R&D for each activity in the short term (2010-2012) - when needed - setting clear goals.
Try to define additional R&D needed to arrive at a TDR in 2015 for each activity & identify schedule critical items.

The CLIC enhancement program aims to provide proof of feasibility by 2010.
In the event of a positive outcome of the feasibility study, the increase of resources
from 2011 onwards will allow for the preparation of a technical design report.

CLIC program towards CDR
2010 resources (CERN and Collaborations) compatible with completion of work program towards a draft CDR (accelerator) end 2010 and a final CDR (including detectors) by June 2011
The Concept of a Multi-TeV Linear Collider based on CLIC technology is mature enough to be described in CDR.
All accelerator feasibility issues are being addressed
A large part of them are or will be demonstrated by the time.
A few of them (stability,…) still need some time to be fully addressed with an R&D program well under way (final results by 2012) and for which preliminary and promising results are already available.
The CDR will include the R&D status, available results and remaining program to fully address CLIC technology feasibility issues
in preparation for the development of a CLIC Technical Design (pending Council approval) with technology optimisation and industrialisation in parallel with R&D completion
Still to be reviewed (peer review Nov 2010) if and when cost figures should be included
ACE’s (wise) comments and advices appreciated
