Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The development of light ion injector and neutralizer for the BES plasma diagnostic system and its first experimental results are presented in this work. This injector will be used for neutral beam plasma diagnostic systems. Diagnostic systems based on neutral beams of Li or Na atoms can be used to study the spatial plasma density profiles, impurity ions and magnetic field distribution in the border region of the plasma fusion devices. This method is based on the detection of the probe beam glow of atoms excited by the plasma electrons. These diagnostic systems consist of two main parts – the neutral beam injector (including the ion beam accelerator and neutralizer) and the secondary light signal registration system. Light ion beam accelerator based on the five-electrode ion-optical system, in contrast to the classical three-electrode system, delivers beams of lithium or sodium with current 3…5 mA at a beam energy 20…25 keV. The neutralizer is based on the supersonic jet of sodium vapor formed by Laval nozzle. The first experiments of neutralizing the ion beam with a transverse supersonic atomic jet was done. |
