SYNCHRO-CURVATURE RADIATION OF CHARGED PARTICLES IN THE STRONG CURVED MAGNETIC FIELDS

Impact of strong magnetic fields on collision mechanism for transport of charged particles

One of the main applications in plasma physics concerns the energy production through thermo-nuclear fusion. The controlled fusion is achieved by magnetic confinement i.e., the plasma is confined into a toroidal domain (tokamak) under the action of huge magnetic fields. Several models exist for describing the evolution of strongly magnetized plasmas, most of them by neglecting the collisions be...

Motion of Charged Particles in Perturbed Magnetic Fields of Tokamak

In this paper we present two Hamiltonian approaches–full and drift–for description of charged particles (e.g. electrons, D + ) in magnetic field of a tokamak. We use a basic magnetic toroidal field configuration with shear plus overlapping island chains creating magnetic ergodic layer. We would like to use this apparatus for solving two physical problems. Firstly for an estimate of generation o...

Arnold Diffusion of Charged Particles in ABC Magnetic Fields

We prove the existence of diffusing solutions in the motion of a charged particle in the presence of ABCmagnetic fields. The equations of motion are modeled by a 3DOF Hamiltonian system depending on two parameters. For small values of these parameters, we obtain a normally hyperbolic invariantmanifold andwe apply the so-called geometric methods for a priori unstable systems developed by A. Dels...

Comparison of the Light Charged Particles on Scatter Radiation Dose in Thyroid Hadron Therapy

Bachground: Hadron therapy is a novel technique of cancer radiation therapy which employs charged particles beams, 1H and light ions in particular. Due to their physical and radiobiological properties, they allow one to obtain a more conformal treatment, sparing better the healthy tissues located in proximity of the tumor and allowing a higher control of the disease.  Objective: As it is well ...
