    International Nano Letters https://doi.org/10.1007/s40089-018-0259-x ORIGINAL ARTICLE Time evaluation of diamagnetic loop and Mirnov oscillations in a major plasma disruption and comparison with a normal shot R. Sadeghi1 · Mahmood Ghoranneviss1 · M. K. Salem1 Received: 21 November 2018 / Accepted: 7 December 2018 © The Author(s) 2018 Abstract In this paper, plasma disruption was investigated in IR-T1 tokamak. Moreover, the time evaluation of plasma parameters such as plasma current, Ip; loop voltage, Vloop; power heating; and safety factor was illustrated. The results of diamagnetic loop and Mirnov oscillations in a major disruption were compared with their results in a normal shot. In addition, plasma disruption in diferent tokamaks was investigated and the results were compared with the IR-T1 tokamak. Keywords Disruption · Runaway electrons · Mirnov coils · Diamagnetic loop · Tokamak · MHD instability Introduction tokamak disruptions cause plasma confinement to be destroyed by restriction of current and density which ends Among various tools of magnetic confnement, tokamak to large mechanical stresses. Plasma disruption is caused containing hot plasma is one of the best and developed by strong stochastic magnetic feld formed due to nonlin- devices [1]. Tokamaks are divided into two groups: frst, the earity excited low-mode number magneto–hydro–dynamics large tokamaks for studying large plasmas such as DIII-D (MHD) modes. The safety factor (q) is very important in [2] and Tore–Supra [3] with high-cost testing conditions and determining stability and transport theory [9–13]. The paper second, small tokamaks such as STOR-M [4] and ISTTOK is organized as follows: in Sect.

Light B.A./B.S., Case Western Reserve University, 2005 A thesis submitted to the Faculty of the Graduate School of the University of Colorado in partial fulfillment of the requirements for the degree of Doctor of Philosophy Department of Physics 2013 This thesis entitled: Imaging and Probe Techniques for Wave Dispersion Estimates in Magnetized Plasmas written by A. D. Light has been approved for the Department of Physics Prof. Tobin Munsat Prof. Martin Goldman Date The final copy of this thesis has been examined by the signatories, and we find that both the content and the form meet acceptable presentation standards of scholarly work in the above mentioned discipline. Light, A. D. (Ph.D., Physics) Imaging and Probe Techniques for Wave Dispersion Estimates in Magnetized Plasmas Thesis directed by Prof. Tobin Munsat Fluctuations in magnetized laboratory plasmas are ubiquitous and complex. In addition to deleterious effects, like increasing heat and particle transport in magnetic fusion energy devices, fluctuations also provide a diagnostic opportunity. Identification of a fluctuation with a particular wave or instability gives detailed information about the properties of the underlying plasma. In this work, diagnostics and spectral analysis techniques for fluctuations are developed and applied to two different laboratory plasma experiments. The first part of this dissertation discusses imaging measurements of coherent waves in the Controlled Shear Decorrelation Experiment (CSDX) at the University of California, San Diego. Visible light from ArII line emission is collected at high frame rates using an intensified digital camera.

  • Book of Abstracts Contribution: T1 / Beam Plasmas and Inertial Fusion
    Book of Abstracts Contribution: T1 / Beam Plasmas and Inertial Fusion Exploring HED physics, ICF dynamics and lab astrophysics with advanced nuclear diagnostics Chikang Li Massachusetts Institute of Technology, Cambridge, MA 02139, USA Significant progress has recently been made in developing advanced nuclear diagnostics for the OMEGA laser facility and the National Ignition Facility (NIF). Both self-emitted fusion products and backlighting nuclear particles have been measured and used to study a large range of basic physics of high-energy-density (HED) plasmas. The highlights of these achievements are manifested by numerous recent publications. For ignition science in inertial-confinement fusion (ICF) experiments, for example, these works have helped to advance our understanding of kinetic effects in exploding-pusher ICF implosions and our understanding of NIF capsule implosion dynamics and symmetry. For basic physics in HED plasmas and laboratory astrophysics, our research contributed to the understanding of nuclear plasma science, the generation and reconnection of self-generated spontaneous electromagnetic fields and associated plasma instabilities, high-Mach-number plasma jets, Weibel-mediated electromagnetic collisionless shocks, and charged-particle stopping power in various laser-produced HED plasmas. In this Tutorials and Topical Lecture, we will present details of these researches.

Feng 2) 1) Department of Physics, Islamic Azad University, Mashhad, Iran, 2) Institute of Physics, Chinese Academy of Sciences, Beijing, China 3) Plasma Physics Research Center, Islamic Azad University, Tehran, Iran E-mail: [email protected] Abstract. Effects of viscosity on magnetohydrodynamics behaviour during limiter biasing in the CT-6B Tokamak has been investigated. The results shown that subsequent to the application of a positive bias, a decrease followed by an increase in the frequency of magnetic field fluctuations was observed. With contribution of viscous force effects in the radial force balance equation for Limiter Biasing, in terms of the nonstationarity model, it allows us to identify the understanding physics responsible for change in the Mirnov oscillations that could be related to poloidal rotation velocity and radial electric field. It could be seen that the time scale of responses to biasing is important. The response of ∇pi, decrease of poloidal rotation velocity, the edge electrostatics and magnetic fluctuations to external field have been investigated. The results shown that momentum balance equation with considering viscous force term can be use for modeling of limiter biasing in the tokamak. 1. Introduction Many experiments have shown the importance of the radial electric field in improved confinement states and several theories can explain the transition mechanism. There are several methods for controlling the radial electric field externally [1,2]. Edge biasing experiments have been found to be important in modifying edge turbulence and transport, but the mechanism of biasing penetration in edge fluctuations and its levels are different with respect to devices operation.

Reactor studies are also being developed for Helical Devices (see e.g. [1-4]). However, a decision on a next step Extrapolation of the knowledge base towards a future stellarator/helical device can only take place when the main fusion power reactor is discussed. Although fusion research results of the current large helical devices in operation or has achieved important milestones since the start and construction have been obtained. The largest helical device continues achieving successes, we show that there are still currently in operation is LHD (Large Helical Device, in the important challenges that have to be addressed before the National Institute for Fusion Science (NIFS), close to construction and operation of an economical fusion power Nagoya, Japan). The construction of the largest stellarator reactor. Both physics and technological questions have to in the world Wendelstein 7-X (Max-Planck Institute, be solved. ITER is a significant step that will lead to major Greifswald, Germany) is nearly finished with first progress; for a DEMO reactor however, there will still be operations foreseen for beginning 2015.

Neu (EFDA CSU) 1.1 Short description. In a fusion power plant, plasma regimes need to ensure a high fusion gain Q (Q=Pfus/Paux). The Lawson criterion sets a limit on the nτE product (with n the density and τE the energy confinement time) to achieve a given fusion gain. The energy confinement time is determined by plasma turbulence that has been progressively controlled by developing of more advanced regimes of operation. Our present understanding of transport processes in plasmas shows that the nτE product increases with the power plant dimension.
