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

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
• Bmax3 T Brad 1.7 T to 2.2 T

4
A-PHOENIX

• CAD Design achieved (05/2006)
• Mechanical parts ordered to industry to LPSC
  workshop (10/06)

HTS Coils
3 T axial field
20K LHe free
2004 HTS Coils Specifications At LPSC
2005 HTS Coils builded at SpaceCryomagnetics LTD
2006 Coils quench protection electronics
designed and builded at LPSC, delivered to
SpaceCryomagnetics LTD

• Final Reception Tests at Culham (UK) in December
  18th-20th 2006
• Delivery at LPSC January 2007

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

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

Planning

• Magnetic system and cryostat are expected for
  the spring 2007
• Mechanics will be available at GSI at beginning
  of 2007
• Microwave generator and ancillary equipment at
  same time
• First beam July 2007
• Test with gaseous beams in DC mode 2nd half
  2007
• Test with metallic beams in DC mode 1st half
  2008
• Test in pulsed mode 2nd half 2008
