ORNL ECR SOUCE

CHRONOLOGY:

• Oringinal ORNL ECR Source in operation since 1984; fabricated with AT funds; was first ECR source worldwide to be exclusively dedicated to study of atomic collisions of multicharged ions

• BES funded source upgrade approved in FY 1991.
  • state-of-the-art CAPRICE ECR source installed

  • number of beam lines expanded

  • improved data acquisition and source control

  • improved the quality of charge state performance

RECENT PROGRESS:

• Mini-oven for metallic species installed and tested Dec. 1993

  • can now produce multicharged ion beams of virtually any element of Periodic Table

• 1 Tesla hexapole installed Nov., 1995

  • provides better electron confinement than original 8.5 kG hexople

FUTURE PLANS:

• Place original ECR source in 200 kV High Voltage Platform to be located in MIRF (AIRM proposal sumitted to BES FY 1993)
  • will permit investigations of new collision mechanisms in little studied velocity regime for multicharged ions

  • will increase capabilities of present experiment (e.g. higher CM energies will mean higher electron energies above threshold measurable im MEIBEL experiment)

  • will prove capability for performing two-source ion-ion collision experiment
