Microstructure of dense plasma columns in Plasma-Focus discharges2016.04.08 9:56 - admin
High-current discharges in plasma-focus-type experimental setups (PF) have been investigated all over the world for many years. The discharges produce intense pulses of both electromagnetic and corpuscular radiation. Range of electromagnetic radiation is very broad: all the way from radio frequencies up to high-energy gamma photons. The produced corpuscular radiation includes beams of fast ions and electrons (emitted along electrode axis direction), and high-energy protons, tritons, alpha particles and neutrons (products of the D-D and/or D-T nuclear reactions).
The fact that columns of dense plasma (the so-called "pinch columns") produced in PF discharges are not homogenous is known for years. Dependence of "pinch" emission on column microstructure was investigated in numerous studies, including recent research on PF-360U facility in Świerk and PF-1000U facility in Warsaw conducted by researchers from TJ5 NCBJ Division. Results of the latter research (in particular X ray emissions) was recently published in Plasma Sources Sci. & Technol. 24 (2015) 055003.
Brief history of research on microstructure of pinch columns and the most significant recently obtained results will be presented.
All interested persons are invited.
