Description
A new tandem type source on the basis of electron cyclotron resonance (ECR) plasma has been constructed for producing synthesized ion beams in Osaka University [1]. Both stage plasmas can be individually operated, and produce ions in which the energy is controlled by a large bore extractor and can also be transported from the first to the second stage. We have already investigated the basic operation and effects of the tandem type electron cyclotron resonance ion source (ECRIS) [2]. It is considered to be suitable for production of new materials, and then we will aim at producing synthesized ion beams as the new source can become a universal source to be available to wide-range mass/charge (m/q) operations. Firstly,we have already produced and extracted multicharged fullerene ion beams on the second stage by using pure C60 vapor source [3]. Next we have been trying to produce endohedral fullerenes in the ECRIS. In the first step, we have been using gaseous material, i.e. nitrogen and argon. In this paper we describe initial experimental results succeeding production of nitrogen-fullerene compounds. Since our final goal is production of metal endohedral fullerenes, e.g. iron endohedral fullerene, we will try to conduct them in the tandem-type ECRIS in the near future.
