One dimensional reduced model for ITER relevant energetic particle transport

Well-Posedness for a One-Dimensional Fluid-Particle Interaction Model

The fluid-particle interaction model introduced by the three last authors in [J. Differential Equations, 245 (2008), pp. 3503–3544] is the object of our study. This system consists of the Burgers equation with a singular source term (term that models the interaction via a drag force with a moving point particle) and of an ODE for the particle path. The notion of entropy solution for the singula...

An alpha particle measurement system using an energetic neutral helium beam in ITER (invited).

An energetic helium neutral beam is involved in the beam neutralization measurement system of alpha particles confined in a DT fusion plasma. A full size strong-focusing He(+) ion source (2 A, the beam radius of 11.3 mm, the beam energy less than 20 keV). Present strong-focusing He(+) ion source shows an emittance diagram separated for each beamlet of multiple apertures without phase space mixi...

one-dimensional pollutant transport model in natural rivers, with emphasis on the role of storage zones

rivers are one of the major resources of drinking and agriculture water, so accurate control and modeling of their water quality is essential for protection of human health and environment stability. transient storage zones have a great effect on contaminant transport, especially in small mountain streams. the main effects include temporary detainment of solute and decrease its concentration in...

Effects of interplanetary transport on derived energetic particle source strengths

[1] We study the transport of solar energetic particles (SEPs) in the inner heliosphere in order to relate observations made by an observer at 1 AU to the number and total energy content of accelerated particles at the source, assumed to be near the Sun. We use a numerical simulation that integrates the trajectories of a large number of individual particles moving in the interplanetary magnetic...
