  1. Scientific highlights of ISIBHI G. Ciavola For the ISIBHI collaboration INFN- GSI- GANIL- JYFL- KVI - TSL- CERN– LPSC - NIPNE EURONS PCC Meeting, Groningen, Holland, 11-12 December 2006 1

  2. Aims to: Improve the knowledge of intense beams production and transport Fulfil all the needs of the major EU accelerator facilities Maintain the EU leadership in the field of ECR ion sources EURONS PCC Meeting, Groningen, Holland, 11-12 December 2006 2

  3. GOALS To design, build and test prototypes of ECRIS with a magnetic field still never reached and frequency ≥ 28 GHz • A Multi-purpose totally Superconducting ECRIS (MS-ECRIS, inspired from the GyroSerse project), with an adjustable magnetic configuration : Bmax = 4 T; Brad = 2.7 T; large ECR zone, f = 28 GHz according to our scaling laws • A more compact source, with a lower magnetic field and an higher power density (A-PHOENIX source) with a technology based on HTS coils and permanent magnets • Bmax=3 T; Brad~ 1.7 T to 2.2 T EURONS PCC Meeting, Groningen, Holland, 11-12 December 2006 3

Highlight : Large Permanent magnet hexapole 3 mm-2.3 T 5 mm-2.1 T 6 mm-2.05 T 2005 Hexapole final design LPSC Iron plates in the plasma chamber wall Iron plates width influence on Br • The strongest permanent hexapole in the world so far (2T on the magnets) 1.6 T in the plasma chamber (without iron plates) • 1.8 to 2.3 T in the plasma chamber using different iron plates geometries EURONS PCC Meeting, Groningen, Holland, 11-12 December 2006 6

  7. A-PHOENIX hexapole assembly status • Last permanent magnets FeNdB received end of July 2006 • Lateral hexapoles builded successfully • Main hexapole assembly to start in late december 2006 Up to now, global planning has drifted of ~3 to 4 months Full program completion by the end of 2008 EURONS PCC Meeting, Groningen, Holland, 11-12 December 2006 7
