6月19日N. Fisch: Methods of RF current drive

题 目: METHODS OF RF CURRENT DRIVE   报告人: Prof. timberland homme Nathaniel Fisch, Princeton Plasma Physics Laboratory, U.S.A   时 间:2013年6月19日(星期三)9:00—11:00   地 点:4号楼6楼中间会议室   Abstract:   Radio frequency waves can penetrate thermonuclear plasmas, depositing momentum and energy with great selectively: in select resonant ions or electrons, in select resonant regions, and with select momentum. doudoune moncler pas cher When these waves are injected asymmetrically with respect to the toroidal direction in tokamaks, they can drive toroidal electric current. Timberland pour hommes The advantage of driving this current by waves is that a tokamak reactor might then be operated in the steady state. doudoune moncler This talk will review at an elementary level the fundamental processes of wave-particle interactions in plasma that underlie the current-drive effect.

6月20日 N. Fisch报告: SOME UNSOLVED CHALLENGES IN RF HEATING AND CURRENT DRIVE

题 目: SOME UNSOLVED CHALLENGES IN RF HEATING AND CURRENT DRIVE

  报告人: Prof. Nathaniel Fisch Princeton Plasma Physics Laboratory, U.S.A

  时 间:2013年6月20日(星期四)9:00—11:00

  地 点:4号楼6楼中间会议室

  Abstract:

  Several unsolved challenges in rf heating and current drive are highlighted. These include current drive in magnetic geometries in which the toroidal magnetic field cannot be assumed to be dominant, current start-up with hyper-resistivity, current drive with oscillating parameters, and synergistic effects between current drive and alpha channeling. These challenges are not necessarily straightforward to address, and it is possible that the challenges cannot even be met, but were they met, at least in some cases, there is the potential of significant consequence.

题 目:Micro-Instabilities of Tokamak Edge Pedestal

主讲人:Weigang Wan(University of Colorado at Boulder, USA. )

时 间:12月6日(周二) 上午9:00

地 点:等离子体所四楼中间会议室

摘 要:

We study micro turbulence of the tokamak edge pedestal with global and flux tube gyrokinetic particle simulations using the electromagnetic particle code GEM. In global simulations, three different sets of DIII-D H-mode experimental profiles are used and the simulation results exhibit quite similar characteristics. The dominant instabilities appear to be two kinds of modes with comparable linear growth rates: a low n, high frequency mode that propagates in the electron diamagnetic direction and a high n, basket timberland low frequency mode that propagates in the ion direction. Bottes UGG Pas Cher France The global results of the high n mode agree with our flux tube simulations, bottes ugg soldes which are well benchmarked against other codes in the same study, bottes ugg including GYRO, soldes puma GTC and HD7. These results are important for the EPED model which is developed to predict the maximum height and width of the edge pedestal.

 题 目:The reactive advanced fluid transport model (Weiland model), background, achievements, present state

 主讲人:Professor Jan Weiland (Chalmers University of Technology,Sweden)

时 间:2012年3月16号上午9:00

地 点:等离子体所601会议室

摘 要:

A brief background is given of transport research up to the end of the 1980’s when advanced fluid models started to be developed.  The new achievements of advanced fluid models are presented with reference to the background physics.

The results include transport coefficients that grow with radius, particle and heat pinches  and the description of the flat density (H-mode) regime. moncler paris All these features go back to an ability to treat the situation with comparable frequency and magnetic drift frequency.  The particular properties of the model developed at Chalmers university (Weiland model) are then described in detail. Finally new features like momentum transport and the generation of transport barriers are discussed.

 

背景介绍:

My research is divided into two main periods. From 1972 till 1980 the work was mainly focused on basic theory of nonlinear wave phenomena with main application to plasmas. The main part of this work was included in the book “Coherent Interaction of Waves in Plasmas” by J. puma pas cher Weiland and H. Wilhelmsson, Pergamon, Press 1977. The later part 1980 – 2010,  has been devoted to stability and transport (mainly transport) in toroidal fusion devices. moncler Doudounes A large part of that work has been summarized in my second book, “Collective Modes in Inhomogeneous Plasmas”, J. timberland Weiland, IOP 2000. bottes ugg pas cher This book is now a standard tool for people doing tokamak transport research. chaussures puma Most recently I organized a workshop “From Leonardo to ITER” in connection with Hans Wilhelmssons promotion to jubilee Dr at Chalmers 2009.
