Toroidal Alfvén Eigenmode Avalanches in NSTX
نویسنده
چکیده
The transport of fast-ions resulting from strongly non-linear Toroidal Alfvén Eigenmode avalanches has been studied experimentally and simulated with the NOVA ideal MHD code and the ORBIT code to model fast ion transport. Detailed measurements of the multi-mode structure and amplitudes have been made to benchmark NOVA calculations of eigenmodes. The ORBIT code has been used to model the fast-ion transport, and good agreement has been found with experimental measurements with the NPA and fast neutron rate diagnostics.

An overview of recent physics results from NSTX
The National Spherical Torus Experiment (NSTX) is currently being upgraded to operate at twice the toroidal field and plasma current (up to 1 T and 2 MA), with a second, more tangentially aimed neutral beam (NB) for current and rotation control, allowing for pulse lengths up to 5 s. Recent NSTX physics analyses have addressed topics that will allow NSTX-Upgrade to achieve the research goals cri...
متن کاملObservation of compressional Alfvén eigenmodes (CAE) in a conventional tokamak
Fast-ion instabilities with frequencies somewhat below the ion cyclotron frequency occur frequently in spherical tokamaks such as the National Spherical Torus Experiment (NSTX). NSTX and the DIII-D tokamak are nearly ideal for fast-ion similarity experiments, having similar neutral beams, fast-ion to Alfvén speed vf /vA, fast-ion pressure, and shape of the plasma but with a factor of two differ...
متن کاملAlfvén wave propagation in initial value MHD simulation in a tokamak geometry
Alfvén wave propagation in an initial value magnetohydrodynamic (MHD) simulation is reported. The simulation result is compared with the theoretical shear Alfvén wave dispersion relation both in a cylindrical geometry and in a toroidal geometry. Generation of the toroidicity induced Alfvén eigenmode (TAE) frequency gap is observed in the presence of 1/R variation of the toroidal magnetic field....
متن کاملEnergetic particles in spherical tokamak plasmas
Spherical tokamaks (STs) typically have lower magnetic fields than conventional tokamaks, but similar mass densities. Suprathermal ions with relatively modest energies, in particular beaminjected ions, consequently have speeds close to or exceeding the Alfvén velocity, and can therefore excite a range of Alfvénic instabilities which could be driven by (and affect the behaviour of) fusion α-part...
متن کاملEvolution of Toroidal Alfvén Eigenmode Instability in Tokamak Fusion Test Reactor
The nonlinear behavior of the Toroidal Alfvén Eigenmode (TAE) driven unstable by energetic ions in the Tokamak Fusion Test Reactor (TFTR) [Phys. Plasmas 1, 1560 (1994)] is studied. The evolution of instabilities can take on several scenarios: a single mode or several modes can be driven unstable at the same time, the spectrum can be steady or pulsating and there can be negligible or anomalous l...
