4.  The scope was slightly changed, and an Integrating Activity “Novel Accelerator Systems” was planned:  Integrating Activity “Novel Accelerator Systems”:  High Gradient RF Structures (estimate 5.5 M€)  Drive beam issues (estimate 5.0 M€)  LED (Luminosity Ensuring Design, 5.4 M€)  GaDGET (Generation & Diagnostic Gear for tiny emittance, 5.9 M€)  FFAG (estimate 5 M€)  Posipol (estimate 6.0 M€)  High power RF (estimate 8 M€)  Laptech (estimate 6 M€)  Total was then 46.8 M€ !  It became clear that this was too much – we asked for guidance how to reduce! 03/4/2009CLIC Meeting 4

5.  Outcome: Recommendation to reduce to 15 M€ total core + 8 M€ optional (for each of the 3 working groups)!  My proposal for WG “NAS” (WG meeting 30-Jul-2007): 03/4/2009CLIC Meeting 5 JRAOldIndicative new coreoptional High Gradient5.5 M€4 M€ EURODrive5 M€2 M€1 M€ LED5.4 M€2 M€1 M€ GADGET5.9 M€3 M€1.5 M€ FFAG5 M€3 M€ Posipol6 M€3.5 M€ HP RF8 M€1 M€ Laptech6 M€ Network+TA1 M€ total46.8 M€15 M€8 M€

6.  Additional requests from the ILC community (damping ring issues, undulator based positron source, low emittance beam transport, laserwire, beam dumps, crab cavity…)  Numbers had been “direct cost” only – now they were to be understood as “total cost” (effective increase by 60%)  After the “EuroCRAB” DS proposal was rejected by EC, an additional request for around 3.8 M€ had to be included.  “Laptech” – which I cut out, suggesting it should go into “Laserlab II” – was partly forced back in.  This was the status as presented in CLIC meeting on 31-Aug-07 and in ESGARD “OMIA”, 10-Sep-07. 03/4/2009CLIC Meeting 6

7.  The accelerator R&D proposals were grouped together.  Jean-Pierre Koutchouk was nominated Coordinator of the Project-to-be “EuCARD”, European Coordination of Accelerator R&D.  The agreed target total cost of EuCARD was 50 M€, with 15 M€ EC request.  “Novel Accelerator Systems” now became a “Work-Package” inside EuCARD – the name became “NCLinac” – the target total was 11.2 M€ with 3.4 M€ EC request. 03/4/2009CLIC Meeting 7

8.  Some fine tuning was done to finish the proposal (DR SC wigglers, positron source, crab cavity, FFAG and Laser plasma acceleration went into other work packages)  The NCLinac budget total in the proposal was 9 M€ total with 2.65 M€ EC request.  The NCLinac proposal contained the following tasks: 03/4/2009CLIC Meeting 8

11. 03/4/2009CLIC Meeting 11 Mark: 5.00 This I3 selectively addresses some of the most critical S&T topics for advanced accelerators, thus laying the groundwork for decisions to be made on future European and Global accelerators in the next 5 years. The concept is sound and the quality of the objectives is world leading. The activities in the framework of this proposal are a useful, more technical complement to FAIR-PP, SLHC-PP, ILCPP, Hi-GRAD and EuroNu-DS. The proposal brings together all the leading European laboratories, and will reinforce and expand existing collaborations. The RTD activities will lead to clear progress beyond the state-of-the-art. These include, for example, prototyping next generation accelerator magnets of ~20T field, of a hybrid Nb3Sn + High-Tc superconductor design, which the Panel considered to be the strongest component of the JRA. It is also gratifying to see a concerted effort within this proposal in normal-conducting RF structures, now that CLIC has been redesigned for X-band, thus allowing the considerable technology investment of the world-wide high energy physics community over the past two decades to be leveraged. The proposal methodology is well-tailored to its objective to shape and inform intermediate-term decisions on future accelerators; it reflects the priorities of the CERN Council for high energy physics, and the ESFRI roadmap more broadly for the accelerator needs of nuclear science and light sources. The JRAs were thus selectively chosen and given precedence over NA and TA activities; and the ongoing R&D investments of the participating labs are highly leveraged. …

12. 03/4/2009CLIC Meeting 12 Mark: 5.00 Responsibility for the management (WP1) resides with CERN, which has long-standing experience in the organisation of large, international collaborations. The partners are the leading EU accelerator labs plus a number of institutes with experience in the relevant fields or who joined recently in the effort. Especially welcome is the participation of industrial firms. The proponents have reached out and involved a large number of non-EU institutions, which will lay the groundwork for a long-term collaborative relationship, when hopefully some of these future facilities enter project construction phase. The consortium is well above the critical mass. Responsibilities and work are well-distributed over the institutes and the EU.

13. 03/4/2009CLIC Meeting 13 Mark: 4.50 A near-term technical impact of this work will be to facilitate the luminosity upgrade of LHC. Later, this work will optimally shape and inform decisions to be made within the time-frame of FP7 about future European and Global accelerator infrastructures. In particular, it may provide a critical catalytic effect for starting the ILC, once the LHC provides some insight about the TeV- scale physics landscape. The impact of this work will also be felt in other fields, particularly x-ray FELs, an increasing number of which are under construction or on the drawing boards around the world. More broadly, this I3 would link nearly all labs in EU which perform accelerator R&D. The large labs have already been well-connected, though this bonding has not been as strong as it could be, as possible synergies have been difficult to discern so far. A number of possible synergies have been taken up within this proposal, apparently under the impetus of the ESGARD Committee. The proposal has the merit to first strengthen the bonding in the fields with potential synergies, and second to include also the smaller institutes and to give them facilitated access to a number of leading-edge facilities, which is important (WP5-7). This will improve the structure in the field of accelerator R&D.

14. 03/4/2009CLIC Meeting 14 The Panel recommends that R&D on high-field magnets are given highest priority. There is considerable potential for cost-savings in the superconducting RF work which is requesting the lion's share of the EC funding. There are two non-EU partners in this proposal: The Russian Research Center "Kurchatov Institute" (RRC KI), which will contribute to studies of materials under thermal shocks; and the Budker Institute of Nuclear Physics (BINP) that will carry out beam dynamics simulations. The Panel agrees that both these institutes are making unique and high -value contributions to this proposal, and thus their participation is well-justified. This proposal builds upon a successful I3 project under FP6 (CARE). The present proposal makes a clear case that this collaboration should be continued and even expanded. In view of the need to achieve long-term sustainable integration of the infrastructures and services offered, the participants should urgently set out to develop lasting structures based on mutual interest, which will allow them to increase the efficiency of their own scientific activities as well as the services they offer to the user community. Activities with this aim should figure prominently in the description of work to be agreed during negotiation. The EC funding for the current proposal should clearly focus on a sustainable integration and on reaching a stronger commitment of the public authorities linked with the participating institutes and/or user communities, allowing a growing independence of external EC funding.

15. ... in spite of these excellent marks, the upper limit of EC funding request was set to 10 M€!  This meant another reduction by 33 %!  This was tough! Of course I made some enemies during this “negotiation” phase, which ended 6-Feb-09... 03/4/2009CLIC Meeting 15
