Characteristics of MINI ECR ion source

Abstract

A very compact electron cyclotron resonance ion source (MINI ECR) was manufactured to extend available energy ranges of ion beams by applying multiply charged ions to electrostatic accelerators. The magnetic field to confine a plasma is formed only by small permanent magnets and the microwave power up to 15 W is generated by a compact transistor amplifier in order to install the ion source at a narrow high-voltage terminal where the electrical power feed is restricted. The magnet assembly is 12 cm in length and 11 cm in diameter, and forms a mirror field with the maximum strength of 0.55 T. The total power consumption of the source is below 160 W. The performance of the source was tested in a bench stand. The results of Ar, Xe, O, and N ion generation are reported in this paper. (author)
