Scientific highlights of ISIBHI
EURONS PCC Meeting, Groningen, Holland, 11-12 December 2006 2Giovanni Ciavola, JRA-07 ISIBHI
JRA-07 Ion Sources for Intense Beams of Heavy Ions (ISIBHI)
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
Aims to:
EURONS PCC Meeting, Groningen, Holland, 11-12 December 2006 3Giovanni Ciavola, JRA-07 ISIBHI
JRA-07 Ion Sources for Intense Beams of Heavy Ions (ISIBHI)
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

Highlight : Large Permanent magnet hexapole
2005 Hexapole final design
LPSC
6 mm-2.05 T
5 mm-2.1 T
3 mm-2.3 T
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
Iron plates width influence on Br
