Collapse of Langmuir solitons in inhomogeneous plasmas
Y. A. Chen, Y. Nishimura, Y. Nishida +1
Propagation of Langmuir solitons in inhomogeneous plasmas is investigated numerically. Through numerical simulation solving Zakharov equations, the solitons are accelerated toward…
Coulomb collisional effects on high energy particles in the presence of driftwave turbulence
B. Huang, Y. Nishimura, C. Z. Cheng
High energy particles' behavior including fusion born alpha particles in an ITER like tokamak in the presence of background driftwave turbulence is investigated by an orbit followi…
Guiding center orbit following calculation of edge particle and heat transport in stochastic magnetic field
C. C. Chang, Y. Nishimura, C. Z. Cheng
Particle and heat transport in tokamak edge is investigated by guiding center orbit following calculation. The guiding center equation is solved for both electrons and ions in the…
Coulomb collisional relaxation process of ion beams in magnetized plasmas
Y. Nishimura
An orbit following code is developed to calculate ion beam trajectories in magnetized plasmas. The equation of motion (the Newton's equation) is solved including the Lorentz force…
