Description
Electron cyclotron resonance ion source (ECRIS)
plasma has been constructed for producing
synthesized ion beams in Osaka Univ.[1,2] We hope
that it can become a universal source capable of
producing ions with wide range mass/charge ration
(m/q). We have been trying to produce endohedral
fullerenes in the ECRIS. We have conducted initial
experiments on production of them only in the
second stage of ECRIS. We have been using iron
vapor source by induction heating (IH) from the
mirror end along to the geometrical axis, and C60
crucible from the side wall, respectively. We
succeeded in realizing ECR plasma that fullerene and
iron ions coexist on the single stage ECRIS, even by
1kV extraction voltage.[3] By these experimental
series, the typical CSD suggests that there is
possibility of slight formation of iron fullerenes
compounds and iron endohedral fullerenes. We are
continuing to investigate the experimental conditions
that maximize spectrum corresponding to iron
endohedral fullerenes. In this paper we describe
preliminary experimental results of synthesizing ironendohedral
fullerene on the ECRIS.
