However, they do pinch toward the tokamak center. As they pinch toward the center, the trapping cone becomes more narrow, so eventually they can be detrapped and run away. When they run away, trapped electrons will have a very different signature from circulating electrons subject to the Dreicer mechanism. The characteristics of what are called trapped-electron runaways are identified and quantified, including their distinguishable perpendicular velocity spectrum and radial extent. 1. Introduction Under acceleration by a constant toroidal electric field, circulating electrons in tokamaks run away when their velocity parallel to the magnetic field is so large that the frictional collision forces become too small to impede acceleration by the electric field. The runaway velocity is the demarcation velocity: the electric field cannot prevent electrons slower than this velocity from slowing down further due to collisions; collisions are too weak to prevent electrons faster than this velocity from undergoing acceleration by the electric field to even higher energies.

  • The Physics of Streamer Discharge Phenomena
    The physics of streamer discharge phenomena Sander Nijdam1, Jannis Teunissen2;3 and Ute Ebert1;2 1 Eindhoven University of Technology, Dept. Applied Physics P.O. Box 513, 5600 MB Eindhoven, The Netherlands 2 Centrum Wiskunde & Informatica (CWI), Amsterdam, The Netherlands 3 KU Leuven, Centre for Mathematical Plasma-astrophysics, Leuven, Belgium E-mail: [email protected] Abstract. In this review we describe a transient type of gas discharge which is commonly called a streamer discharge, as well as a few related phenomena in pulsed discharges. Streamers are propagating ionization fronts with self-organized field enhancement at their tips that can appear in gases at (or close to) atmospheric pressure. They are the precursors of other discharges like sparks and lightning, but they also occur in for example corona reactors or plasma jets which are used for a variety of plasma chemical purposes. When enough space is available, streamers can also form at much lower pressures, like in the case of sprite discharges high up in the atmosphere. We explain the structure and basic underlying physics of streamer discharges, and how they scale with gas density. We discuss the chemistry and applications of streamers, and describe their two main stages in detail: inception and propagation. We also look at some other topics, like interaction with flow and heat, related pulsed discharges, and electron runaway and high energy radiation. Finally, we discuss streamer simulations and diagnostics in quite some detail. This review is written with two purposes in mind: First, we describe recent results on the physics of streamer discharges, with a focus on the work performed in our groups.

Fusion energy will be the ultimate clean energy source for mankind. The ITER device under construction by international partners will bring this goal one-step closer 1,2. Before constructing the first prototype fusion power plant, one of the most visible concerns that needs to be addressed is the threat of deleterious runaway electrons (REs) produced during unexpected disruptions of the fusion plasma 3-7. Massive REs can carry up to 70% of the initial plasma current in ITER, and understanding their dynamical behavior is crucial to assess the safety of ITER. However, the complex dynamics of REs in a realistic fusion reactor is almost impossible to simulate numerically because it requires efficient long-term algorithms and super-large scale computing power 8,9. In the present study, we deploy the world’s fastest supercomputer, Sunway TaihuLight 10,11, and the newly developed relativistic volume-preserving algorithm 12 to carry out long-term particle simulations of 107 sampled REs in 6D phase space.

Brennan Princeton University, Princeton, NJ, United States of America Andrey Lvovskiy Oak Ridge Associated Universities, Oak Ridge, TN, United States of America Carlos Paz-Soldan General Atomics, San Diego, CA, United States of America Eric D. Fredrickson Princeton Plasma Physics Laboratory, Princeton, NJ, United States of America Amitava Bhattacharjee Princeton Plasma Physics Laboratory, Princeton, NJ, United States of America Princeton University, Princeton, NJ, United States of America Abstract. Compressional Alfv´en eigenmodes (CAE) driven by energetic ions have been observed in magnetic fusion experiments. In this paper, we show that the modes can also be driven by runaway electrons formed in post-disruption plasma, which may explain kinetic instabilities observed in DIII-D disruption experiments with massive gas injection. The mode-structure is calculated, as are the frequencies which are arXiv:2009.11801v3 [physics.plasm-ph] 2 Oct 2020 in agreement with experimental observations. Using a runaway electron distribution function obtained from a kinetic simulation, the mode growth rates are calculated and found to exceed the collisional damping rate when the runaway electron density exceeds a threshold value. The excitation of CAE poses a new possible approach to mitigate seed runaway electrons during the current quench and surpassing the avalanche. Compressional Alfv´eneigenmodes excited by runaway electrons 2 1.

Printed in Sweden by Reproservice Chalmers Tekniska H¨ogskola G¨oteborg, Sweden, 2020 Kinetic modeling of runaway-electron dynamics in partially ionized plasmas LINNEA HESSLOW Department of Physics Chalmers University of Technology Abstract An essential result of kinetic plasma physics is the runaway phenomenon, whereby a fraction of an electron population can be accelerated to rel- ativistic energies. Such runaway electrons are formed in astrophysical settings, but are also of great practical relevance to fusion research. In the most developed fusion device, known as the tokamak, runaway electrons have the potential to cause severe damage to the first wall. Runaway-electron mitigation is therefore one of the critical issues in the design of a fusion power plant. In many situations, runaway electrons interact with partially ionized atoms. In particular, the currently envisaged mitigation method for tokamaks is to inject heavy atoms which collisionally dissipate the run- away beam before it can collide with the wall, or prevent it from forming at all.

Box 11365-9567, Tehran, Iran ͑Received 10 July 2008; accepted 14 December 2008; published online 16 January 2009͒ Set of experiments has been developed to study existing runaway electrons in “Damavand” tokamak plasma upon characteristics of hard x-ray emissions produced by collision of the runaway electrons with the plasma particles and limiters. As a first step, spatial distribution of hard x-ray emissions on the equatorial plane of the torus was considered. Obtained spectra of hard x-ray emissions for different alignments of shielded detector indicate isotropic emissivity in the equatorial plane. This is in agreement with wide angle cone of bremsstrahlung radiations, deduced from the mean value of energy of the runaway electrons. The mean energy was calculated from the slope of the energy spectrum of hard x-ray photons. In the second stage in order to investigate time evolution of energy of the runaway electrons, similar technique were applied to obtain hard x-ray energy in every 3 ms intervals, from the beginning to the end of plasma.
