Dynamic Charge Transport Behavior of Double-layer Thin Film Materials Under Electron Beam Irradiation

Guang-Yu Sun

Spacecraft dielectrics in the complex space environment often suffer charging and discharging, causing on-orbit anomalies and failures. Studying charge transport in the dielectric during a spacecraft's charging process is crucial. It helps take measures li ...

Oblique streaming waves observed in multipactor-induced plasma discharge above a dielectric surface

Guang-Yu Sun, Haomin Sun

In a recent discovery (Wen et al 2022 Phys. Rev. Lett. 129 045001), streaming waves were found in multipactor-induced plasma discharges. However, due to the limitations of a 1D simulation setup, these waves displayed only transverse dynamics. In this lette ...

The role of neutral baffling in closed divertor for nitrogen-seeded detachment in TCV tokamak

Guang-Yu Sun

Excessive power exhaust on divertor target remains a critical challenge for magnetic confinement fusion reactor based on the tokamak concept. If unmitigated, the power received on the divertor target will far exceed the material limit of 5-10MW/m2 in futur ...

Neutral pressure measurement in TCV tokamak using ASDEX-type pressure gauges

Holger Reimerdes, Marcelo Baquero Ruiz, Guang-Yu Sun, Elena Tonello, Marc Noël, Mateusz Gospodarczyk, Hammam Elaian

Probing the neutral gas distribution at the edge of magnetic confinement fusion devices is critical for plasma exhaust studies. In the TCV tokamak, a set of ASDEX-type hot ionization pressure gauges (APGs) has been installed for fast, in situ measurements ...

On the Ohmic-dominant heating mode of capacitively coupled plasma inverted by boundary electron emission

Haomin Sun, Guang-Yu Sun

Electron emission from the boundary is ubiquitous in a capacitively coupled plasma (CCP) and precipitates nonnegligible influence on the discharge properties. Here, we present Particle-in-Cell/Monte Carlo Collision simulation of an Ohmic-dominant heating m ...

Characterization of transversely confined electron beam-generated plasma using two-dimensional particle-in-cell simulations

Guang-Yu Sun, Haomin Sun

Electron beam-generated plasmas (EBPs) have been used to modify the surface properties. In certain applications, EBPs are transversely confined and their properties are of value to the treatment. In this paper, the characteristics of an electron beam-gener ...
