The prototype of radioactive ion source

Abstract

The design and experimental results of the RIB source prototype are presented. A source will have the container of ²³⁵U compounds heated up to 2200-2500°C. Vapors of uranium fission obtained when the ion source is irradiated by the high-energy neutron flux, are then ionized and extracted from the source. In the experiments with the prototype loaded by ¹²C the source working temperature 2700°C was reached, the carbon ion current 10 nA was obtained. The total operation time of more than 100 hours with no performance degradation was demonstrated.
