Preparation of the IA proposals within
FP7 Working groupNovel Accelerating Systems

• Erk Jensen (CERN) for the working group
• Brigitte Cros (LPGP, U Paris Sud), Gilbert
  Guignard (CERN), Alban Mosnier (CEA/Dapnia),
  Vittorio Palladino (INFN Napoli), François
  Richard (LAL/IN2P3)

A brief history

• At CARE06
• Idea IA Novel Acceleration Systems (NAS, one
  of 3 planned IAs),
• Consisting of 10 JRAs,
• Based on Letters of Intent received by ESGARD
• Total cost then estimated to 83 M
• Dec. 06 after 1st round of concentration/de-scopi
  ng/merging
• Total cost estimate reduced to 55 M
• Jan. 07 CLIC new parameters announced
• Total cost estimate 48 M
• Proposed to define MICE as TA
• Remaining 8 JRAs, 2 TA (MICE CTF3)
• June 3 IAs to be joined into 1!
• Reduction requested to total cost of lt30 M (!),
  we request guidelines from ESGARD. At the same
  time
• ILC GDE Europe come with additional requests (DR,
  BDS, positron source, low emittance beam
  transport instrumentation)

A brief history (contd.)

• July 23rd 07 extended ESGARD meeting with
  directors, guidelines
• Prepare for one IA only,
• Define activities Core (15 M) and Additional
  (lt 8 M),
• Assume ratio contributed/requested budget of 2/1,
• Use the Strategy Document to define priorities.
• Consider to
• Expatriate Laptech to Laserlab II
• Postpone Posipol to a later call!
• End of July I asked the potential collaborators
  for detailed feedback, in particular concerning
  commitments for the matching funds. The received
  feedback showed
• A huge interest to collaborate,
• that the labs are ready to commit money (a lot!),
• that this is not a way to reduce the overall
  budget volume (back up to gt50 M)!

A brief history (contd.)

• Sept. 07 ESGARD OMIA Priorities from
  ILC/GDE-Europe and CLIC received,
• Oct. 15th 2nd extended ESGARD meeting with
  directors, presented core and additional as
  requested. Outcome of the meeting
• Retain core only,
• Assume 70k/FTEy throughout,
• Assume ceiling of 15 M for EU contribution
  (strict!)
• Further reductions (after Oct. 15th)
• Reduce by 10 to reserve budgets for NAs and
  TAs
• Reduce (by about 3) to include crab-waist
  proposal
• As a result, we had to implement further
  reductions, and
• I have to apologize that I had no time to inform
  the concerned parties about these rapid and
  drastic changes!

The reductions of October (EU part only)
Proposal presently under discussion!

In the following, I will present this present
proposal under discussion!
Preliminary!

• 9 work-packages remain
• NC high gradient, Stabilisation, BDS, Drive beam
  phase, Beam Dumps, DR Vacuum, DR SC wiggler,
  FFAG, Positron source
• Of these, I assume that
• FFAG will be in the new JRA ANAC,
• the others will be joined in the JRA NCLinac,
  which I will concentrate on.
• Should DR SC wiggler be joined with other SC
  magnets? In the following, I assume this also.
• I again ask your understanding, but we seem to be
  aiming at a quickly moving target!
• I also assume that EC contribution is 30 of
  total.

NCLinac, WP1 Normal-Conducting High-Gradient
research
Preliminary!

• Building on the success of CTF3 and complementing
  it,the goal of WP1 is to optimize CTF3 and its
  use towards
• cost- and performance optimized accelerating
  structures and
• their integration in CLIC modules. This also
  requires
• better modelling of breakdown and
• better suppression of HOMs,
• experimental verification
• Partners CIEMAT, Cockcroft/Manchester,
  HIP/Helsinki, Uni Uppsala, (CERN)
• Estimated total 2.8 M
• This WP is complementary to the module
  implementation which is financed 100 by CERN
  and not part of this proposal.

• other absorber materials He, Li, LiH, etc..
• LN2 cooled RF cavities

Summary

• From the initial ideas (IA NAS) until now, this
  has been a difficult and painful process and
• it isnt over but we must proceed fast
• Next deadline deliverables, milestones, schedule
  and 1st level WBS 21st Oct. 2007!
• Part of what I presented is in discussion and
  preliminary, but I needed to provoke your
  reaction!
• My apologies again I wasnt able to keep you
  informed about these recent, rapid changes!
• Thank you!
