Analysis Of The Structure Of Ion Micro-Beams Emitted From RPI- And PF-Type Facilities

Abstract

The paper concerns measurements and quantitative analysis of micro‐beams of fast ions produced by high‐current pulse plasma discharges, which are investigated within different experimental facilities of the Rod Plasma Injector (RPI) and Plasma‐Focus (PF) type. The reported ion measurements were performed mainly within the RPI‐IBIS device at the IPJ in Swierk and within the large PF‐1000 facility at the IPPLM in Warsaw. The pulsed ion streams were recorded by means of ion‐pinhole cameras equipped with solid‐state nuclear track detectors (SSNTD). Before their irradiation those detectors were calibrated, i.e. their responses to different ion species of various energies were determined. For this purpose there were used mono‐energetic ion beams (obtained from particle accelerators) or ion tracks measured along the ion parabolas recorded by means of a Thomson‐type spectrometer. During the described ion measurements the ion‐pinhole cameras were placed at different angles to the symmetry axes of the investigated experimental facilities.
