Full-wave computation of SUb-atmospheric Radio-frequency Engine (SURE)
Dingzhou Li, Lei Chang, Ye Tao
Near-space, which covers altitudes from 20 to 100 kilometers, has been receiving more and more attention because of its special strategic value. Airships and high-altitude balloons…
Exploration on the Two-stream Instability in the Polar Cusp Under Solar Storm Disturbances and its Potential Impacts on Spacecraft
Jikai Sun, Lei Chang, Yu Liu +6
During solar storms, the polar cusp often exhibits electron populations with distinct velocity distributions, which may be associated with the two-stream instability. This study re…
Exploration of novel ICP using helicon antennas with zero magnetic field
Ye Tao, Lei Chang, Dingzhou Li +1
Inductively coupled plasma (ICP) attracts great attention from aspects of fundamental research and practical applications, and efficient power coupling is highly desirable for both…
The bump-on-tail instability excited by energetic electrons in helicon plasma
Shi-Jie Zhang, Dong Jing, Lei Chang +10
This work explores for the first time bump-on-tail (BOT) instability excited by energetic electrons in helicon plasma. The Berk-Breizman model that developed for the wave-particle…
Spatial and temporal evolutions of blue-core helicon discharge driven by planar antenna with concentric rings
Chao Wang, Lei Chang, Ling-Feng Lu +9
The spatial and temporal evolutions of blue-core helicon discharge driven by a planar antenna with four concentric rings are explored on the Linear Experimental Advanced Device (LE…
