Include a Beam Experimental Program 2. Include Medium Labs, Universities, and Polish Labs Remark: SPL cavities in the scope of “HE-HI-Protons” Working Group

31 October 2007CARE'074 Major Existing Facilities DESY : FLASH Linac and TTF RF Infrastructure (CHECHIA, Clean Rooms, EP, …). CERN : SC RF Infrastructure (SM18), LHC Injectors, REX-Isolde Orsay-Saclay : SupraTech RF infrastructure (1.3 GHz MHz, CryHoLab, Coupler) Cockcroft Institute : Daresbury RF Infrastructure (ERLP  4GLS) Rossendorf FZD : ELBE Linac and SC-RF Gun (1.3 GHz) BESSY : 1.3 GHz RF (HoBiCat) TU Darmstadt : DALINAC (3 GHz)

31 October 2007CARE'075 Main Assumptions for the “Core” and “Additional Activities” Only direct costs : Manpower (70 k€/y) + Material + Travel. Overheads will be counted later. The EU request is 1/3 of the direct cost for every participant. (while the EC rule for RTD activities is maximum 75% of the total cost including overheads)

31 October 2007CARE'076 Proposal for a JRA Structure for a Superconducting RF Acceleration Systems (SRFAS) Integrated Activity including all the Letters of Intend: JRA1 : High Gradient Cavities (Dieter Proch) JRA2 : Cavity Prototypes (Peter McIntosh, Matteo Pasini, Jacek Sekutowicz) JRA3 : Thin Films (Bernard Visentin) JRA4 : Accelerator and Beam Studies (Roger Jones, Mariusz Grecki, Jochen Teichert) JRA5 : RF Test Infrastructures (Wolfgang Weingarten) OMIA Speakers : Green : describe (defend) their proposal Purple : review (evaluate) the proposals

31 October 2007CARE'077 Proposal for a JRA Structure for Superconducting RF Acceleration Systems (SRF-AS) merged into a single Integrated Activity : JRA : “SRF Too” WP1 : SC Cavities WP2 : Accelerator and Beam Studies WP3 : RF Test Infrastructures as presented at the ESGARD Meeting with the Lab Directors on October 15, 2007 with the aim to negociate ~5 M€ out of the 8 M€ of additional activities

31 October 2007CARE'0712 Activities Left Out : 10.9 M€

31 October 2007CARE'0713 Proposal for Thin Films Activities About 1.5 M€ is saved for Thin Film Activities (i.e. 0.5 M€ from EU) to serve a large community of interested laboratories. But the Proposals from CERN, IPJ, Roma2, Roma3, DESY, LNL and need to be re-organized around the following principles: 1.There are 2 rock-solid users for Thin Film Cavities : a) LHC Ring for 400 MHz elliptical cavities b) Rex-Isolde for 101 MHz Quarter-wave cavities both using the Nb/Cu magnetron sputtering technique. 2. There are proposals for alternative, not yet proven, Nb/Cu coating techniques: a) arc coating (cf. CARE/SRF), successful for Pb/Nb photocathode b) “enhanced” magnetron sputtering c) atomic layer deposition 3. There are proposals to coat new materials, e.g. A15 High Tc superconductors to increase E peak and Q0 4. There is a rich network of coating, characterization and RF test facilities across Europe I have invited Mats Lindroos (CERN) to build a new proposal along these principles

31 October 2007CARE'0714 Proposal for SCRF Gun Beam Tests at ELBE FZD at Rossendorf is offering to use their ELBE linac beam time, including the SCRF Gun (CARE/PHIN) and Beam Line diagnostics, to develop new SCRF Gun concepts: 1.Polarized electron gun 2.Emittance compensation methods 3.SCRF Gun experiments for a Total Cost of 630 k€ Items removed: 4.LASER pulse shaping 5.New large grain RF cavity

31 October 2007CARE'0720 Proposal for a Trans National Access FLASH-TTF with a budget < 500 k€ with the aim to provide travel expenses for Visitors to run experiments at FLASH (DESY) and/or to test cavities in TTF RF Infrastructure. Withdrawn by DESY : too much organisation and paper work for a small benefit.
