Analysis of toroidal Alfven eigenmode-induced fast ion losses in Globus-M2 spherical tokamak

چکیده

With an increase of magnetic field up to 0.8 T and plasma currentto 400 kA, fast ion losses rate in the discharges with toroidal Alfveneigenmodes decreased tokamak Globus-M2 comparing Globus-M tokamakdischarges. Taking into account data on increasedmagnetic current, regression fit neutral particleanalyzer flux drop energy channel close beam onrelative eigenmode magnitude, value currentwas analyzed. The power dependence TAE magnitude was foundto be ~0.5 inverse proportional product magneticfield which is highly likely determined only byplasma current due weak field. resultobtained indicates that Globus-M2, stimulated by toroidalAlfven eigenmodes are mostly shift passing orbits tothe edge. field,neutron drops arising moments mode bursts have alsodecreased.

Fast Compressional Alfven Waves in a Tokamak

Enhancement of cyclotron damping is theoretically evaluated based upon the wave E-field polarization which is modified by the two-ion hybrid resonance. The degree of enhancement and its asymmetry about the plasma center is consistent with experimental observations. The enhancement factor is very large at low plasma densities at which most of the past damping strength measurements have been repo...

Fast-Ion Transport Induced by Alfven Eigenmodes in ASDEX Upgrade

A comprehensive suite of diagnostics has allowed detailed measurements of the AE spatial structure and subsequent fast-ion transport. RSAEs and TAEs have been driven unstable by fast-ions from ICRH as well as NBI origin. In ICRF heated plasmas, diffusive and convective fast-ion losses induced by AEs have been characterized in fast-ion phase-space. While single RSAEs and TAEs eject resonant fast...

Evolution 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...

A Study of Prompt Fast Ion Losses From Neutral Beam Injection in the DIII - D Tokamak

A study of the prompt losses of injected neutral beam born fast ions was conducted on the DIII-D tokamak at General Atomics using scintillator based fast ion loss detectors (FILD) and a reverse orbit calculation code. Prompt losses, also called first orbit losses, result from injected neutrals that are ionized on orbits that terminate to the outer wall before making a complete neoclassical, pol...
