Development of Electron Cyclotron Resonance Ion Source for Synthesis of Endohedral Metallofullerenes.

A new electron cyclotron resonance ion source (ECRIS) has been constructed for synthesis of endohedral metallofullerenes. The main purpose of the ion source is to produce new biological and medical materials. The design is based on ECRIS for production of multicharged ion beams with a traditional minimum-B magnetic field. An 8–10 GHz traveling wave tube (TWT) amplifier and a 2.45 GHz magnetron have been applied as microwave sources. Fullerene and metal vapor are introduced with a filament heating micro-oven and an induction heating oven, respectively. In preliminary ion-extraction test, Ar⁺ is 54 μA. Many broken fullerenes such as C₅₈ and C₅₆ are observed in fullerene ion beams. [ABSTRACT FROM AUTHOR]
