Orbits of relativistic electrons in a perturbed tokamak magnetic
field
Orbits of relativistic electrons accelerated to 99% of the speed
of light in a stochastically perturbed tokamak magnetic field
are shown. Theoretically it was thought that the confinement of
relativistic electrons would not deteriorate in such a perturbed
field. Our present study revealed for the first time that macro-scale
magnetic perturbations can destroy the confinement of relativistic
electrons by deviating their motion along the magnetic field lines
from inside of the plasma, that leads to a rapid loss of electrons
from the plasma surface. |
