Special Issue Information

Dear Colleagues,

We have the pleasure of inviting you to submit your future articles in our Special Issue, entitled: Advances in Fundamental and Applied Fusion Research Domain". At present, fusion research is receiving a great deal of interest, due to many future applications, especially in obtaining clean and cheap energy via thermonuclear plasma (e.g. ITER, DEMO, PROTO). In this line, a wide range of experiments are currently underway in order to detect future problems or future improvements. One of many challenges is to analyze and simulate the plasma behavior inside tokamaks during its lifetime: here we can think about the consequences of the plasma–wall interactions, which usually lead to the formation of melting spots, and exotic structures where tritium could be trapped, producing further problems, and so on.

The goal of our Issue is to highlight the latest results in the fusion research domain. The topics cover a wide range of scientific interests: from lab-scale plasma experimental systems, plasma diagnostics, material investigations, and simulations, up to robotics and cyber-applications.

The topics of our Special Issue are presented in the following (not an exhaustive list):

  • Lab-scale plasma experimental systems comparable to fusion phenomena (filamentary discharges, jets, glow discharges, etc.);
  • Plasma–material interaction: studies on erosion, cracks, dusts, fuzz, and the formation of exotic structures;
  • Tritium trapping in dust produced during plasma operation (W);
  • LOVA and LOCA issues and waste management;
  • Elastic recoil detection analysis for hydrogen, deuterium, and light elements profiling investigations.
  • In situ coating repair;
  • Modelling of interfaces in PFC;
  • Computation, robotics, and cyber-applications for fusion research sector development.

In this paper, results concerning hydrogen and deuterium plasma (RF, 13.56 MHz) interactions with tungsten surfaces, were reported. We used the Hollow-Cathode (HC) configuration for plasma–tungsten surface interaction experiments, along with the collection of tungsten dust, at different distances. Further on, the plasma-exposed tungsten surfaces and the collected dust were morphologically analyzed by contact profilometry, scanning electron microscopy, and energy dispersive spectroscopy measurements, along with chemical investigations by the X-ray photoelectron spectroscopy technique. The results showed that exposing the tungsten surfaces to the hydrogen plasma induces surface erosion phenomena along with the formation of dust and interconnected W structures. Herein, the mean ejected material volume was ~1.1 × 105 µm3. Deuterium plasma facilitated the formation of blisters at the surface level. For this case, the mean ejected material volume was ~3.3 × 104 µm3. For both plasma types, tungsten dust within nano- and micrometer sizes could be collected. The current study offers a perspective of lab-scaled plasma systems, which are capable of producing tungsten fusion-like surfaces and dust. Full article
