Special Issue Information

Dear Colleagues,

Recent progress in plasma diagnostics has been closely related to the creation of new scientific equipment, experimental measurement techniques, and related mathematical analyses. The increased reliability and accuracy of invasive probe methods, the use of passive and active spectroscopy systems, including neutron spectroscopy, as well as the development of new approaches and data processing algorithms are ongoing. The success of the controlled thermonuclear fusion program is closely connected with the capability of the diagnostic systems used for fundamental physical research and for the control of plasma parameters in experimental installations.

We are pleased to present a Special Issue of Applied Sciences that will cover new advances in diagnostic methods for low- and high-temperature plasma and their application to scientific research and industry. Areas of interest include plasma diagnostics methods and their application to fusion setups and reactors as well as their use for pulsed and stationary gas discharge in research and technological installations. Potential authors are encouraged to contact the Guest Editors with questions about the suitability of their research prior to submission.

The article presents a method of mathematical correction to be applied to the results of measuring the intensity of spectral lines using charge-coupled devices (CCDs) in the presence of the blooming effect. This technique is particularly applicable in atomic emission spectroscopy. It enables expansion of the dynamic range of spark emission spectrometers and significantly minimizes the result distortions of the measurements taken in the area of high element concentrations. The authors devised a mathematical model and proposed an algorithm to adjust the measured intensity of analytical lines at the photo detector upper limit, in addition to an algorithm for processing data from the spectra recording system. The proposed mathematical algorithm was integrated into the software for the SPAS-02 and SPAS-05 spark spectrometers produced in Russia, and tested in determining the chemical composition of steels. The findings show that the actual dispersion of the analytical line intensity distribution may exceed the measured dispersion by a factor of 1.5, and their intensities may differ by a factor of 2. This algorithm may be implemented in atomic emission spectrometer software and makes it possible to adjust the calibration curves for a range of high alloying element concentrations when the analytical line intensity is at the upper limit of the CCD dynamic range.

Doppler backscattering (DBS) is a microwave diagnostics method typically used to study the plasma rotation velocity. Apart from conventional techniques, more advanced forms of DBS implementation were suggested on Globus-M. More specifically the study of a variety of oscillating processes was performed using DBS. In this review we present a detailed description of all of the methods and techniques employed in Globus-M alongside results obtained using DBS in all the years up until the shutdown of the tokamak. These include research similar to that done on other devices into the properties of such phenomena like geodesic acoustic modes or limit cycle oscillations, along with innovative works regarding the detection and investigation of Alfven eigenmodes and filaments that were the first of their kind and that provided important and novel results. Apart from that, the specific aspects of DBS application on a spherical tokamak are discussed. An in-depth look into the gradual change and improvement of the DBS diagnostics on Globus-M is also presented in this paper. Full article
