12 Linear IFMIF Prototype Accelerator MEBT (Medium Energy Beam Transport Line) Utmost attention advices the bunchers, which synchronizes the beam configuration (bunched) with the 175 MHz of the superconducting cavities. The beam power they must handle is unprecedented 125 ma x 5 MeV = 625 kw I. Podadera et al, The Medium Energy Beam Transport Line (MEBT) of IFMIF/EVEDA LIPAc, IPAC11, San Sebastián 12

13 Linear IFMIF Prototype Accelerator Superconducting HWR resonator at 175 MHz E input = 5 MeV E output = 9 MeV Beam loss < 10W E acc =4.5 MeV/m Max transm. RF power = 70 kw 13

14 Linear IFMIF Prototype Accelerator Diagnostics and Diagnostic Plate CIEMAT in collaboration with CEA (France) and INFN (Italy) Represents an important challenge due to: High intensity; high power Low energy; low b Diagnostics (interceptive and noninterceptive) all along the accelerator line for control and characterizing the beam (more that 16 instrumentation at DP) 14

15 Linear IFMIF Prototype Accelerator HEBT (High Energy Beam Transport Line) It transports the 9 MeV beam to the beam dump. A bending magnet reduces the neutron and gammas backscattering towards upstream components. A magnetic beam expander reduces the power density on the beam dump to design values (< 200 kw/cm 2 ); furthermore, a lead shutter, closed during beam shutdown act as a gamma shield from the activated beam dump Main Components: Quadrupoles Dipole Diagnostics Lead shutter Other important components: Cooling system Vacuum system Magnets power supply Local Control System Mechanical supports 15

39 Conclusion from AHG Panel Two European Union member state countries, Croatia and Spain, filed in a technical proposal to host the facility. Report conclusions: The Spanish proposal entirely fulfils all requirements and assumption.the Granada site present unique characteristics and is fully operational: construction works could start immediately. The national experience in building and operating nuclear facilities, the presence of waste management and storage facilities, the national scientific and technological competences both on particle accelerators and nuclear installations, is at the highest international standard. From a Spanish-Croatian communication to the F4E Governing Board Spain and Croatia have reached an agreement to support the proposal to site the IFMIF-DONES project in Granada (Spain) or, if not possible for technical reasons, in the site close to Zagreb (Croatia)... From the F4E Governing Board Record of Agreements The F4E GB welcomed the agreement of Spain and Croatia to join forces to promote Granada as European site for IFMIF-DONES. The joint proposal provides a strong basis for hosting DONES in Europe, an essential facility for the successful implementation of Fusion energy. The final choice of the location in Europe or Japan will be taken in the context of a possible continuation of the collaboration between Japan and Europe. As a consequence, if DONES is built in Europe, it will be built in Granada (Spain) Sep. CDTI, 27, octubre Page

40 IFMIF/DONES What happens next? While still not clear whether Japan will express interest in hosting DONES, opening new round of negotiations, Europeans are moving ahead: Engineering activities within EUROFusion Consortium are progressing well, now being developed for Granada site. Structural Funds application is being prepared by the joint team In parallel, the joint team is seeking the help of F4E and the European Commission to develop the best possible approach and discuss the different phases of the project. All going well, IFMIF-DONEs construction should start in early 20 s 40
