Radio frequency induction plasma generator 80‐kV test stand operation

Beam extraction tests at energies up to 80 kV were performed using a radio frequency induction (RFI) plasma generator hydrogen ion source. A 7×10‐cm2, long pulse accelerator was operated with a 10×10‐cm2 axial magnetic cusp bucket and a magnetic‐filter bucket. Atomic fractions (up to 85% H+), plasma...

Description
Summary:Beam extraction tests at energies up to 80 kV were performed using a radio frequency induction (RFI) plasma generator hydrogen ion source. A 7×10‐cm2, long pulse accelerator was operated with a 10×10‐cm2 axial magnetic cusp bucket and a magnetic‐filter bucket. Atomic fractions (up to 85% H+), plasma production efficiencies (≊0.6 A of beam per kW rf power), and beam divergence were at least as good as with arc plasmas in similar chambers. Potential advantages of the RFI plasma sources for large‐scale applications are ease of operation, reliability, and extended service life.
