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
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
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
A-PHOENIX • CAD Design achieved (05/2006) • Mechanical parts ordered to industry & to LPSC workshop (10/06) EURONS PCC Meeting, Groningen, Holland, 11-12 December 2006 4
