60 GHz ECR ion CAD

• Size and cost reduction without changing

• Internal characteristics unchanged

Production of B and Li

• B* and Li* are produced by irradiating a target. How is Boron or Lithium when it get out from the target?

• Atoms – Ions – Molecules? What are the possibilities?
• If we have molecules => they should be broken in the plasma
• If we have ions => use the 1+/n+ method

• Solutions:

• Metallic vapor, efficiency ~ 1 – 10 %
• Sputtering, efficiency ~ 1 % (energetic atoms)
• Extract species using offline chemical separation techniques, efficiency ~ 10 % 7Be is produced by irradiating a lithium target (30 μA of 27 MeV protons) and is extracted by this way (Loiselet et al. Louvain-La-Neuve)
