On 30 October 2024, at 4:00 PM, the Association of Young Scientists and Specialists at JINR invites everyone interested to the next seminar that will take place in the Big Hall of the JINR Scientists’ Club (6, Joliot-Curie street, left side).

Candidate of Physics and Mathematics, Head of the Plasma Diagnostics Laboratory at the Troitsk Institute of Innovative and Thermonuclear Research (TRINITY) Alexandra Kartasheva will deliver her report “Experimental study of the characteristics of a plasma flow generated in a quasi-stationary plasma accelerator (QSPA)”.

One of the promising areas for using plasma accelerators is the development of powerful electric jet plasma rocket engines based on them. The study of the spatiotemporal characteristics of the discharge and plasma flow generated by the QSPU will allow optimising the QSPA geometry and operating modes to ensure stable operation and reduce the role of dissipative processes.

The speaker will present the results of studying the spatial-temporal dependences of the characteristics of hydrogen plasma flow in the QSPU. The spatial-temporal structure of discharge radiation in the interelectrode gap will be explained. The work that the report is based on shows that at the output of the electrode system of the accelerator there is a bright luminescence region characterised by the presence of impurities of the electrode system materials and increased values ​​of the electron density. The time dynamics of the plasma flow concentration was measured simultaneously for the first time using two independent optical diagnostics.
