Control of fluctuations in ECR plasma by applying multipole magnetic fields
Hayato Tsuchiya, Mayuko Koga, Masayuki Fukao +1
The control of fluctuations generated in an electron cyclotron resonance (ECR) plasma is attempted by changing microwave powers. It is found that when a cage is introduced in the v…
Control of the chaotic state caused by the curent-driven ion acoustic instabilit and dynamical behavior using delayed feedback
Takao Fukuyama, Christian Wilke, Yoshinobu Kawai
Controlling chaos caused by the current-driven ion acoustic instability is attempted using the delayed continuous feedback method, i.e., the time-delay auto synchronization (TDAS)…
Melting of 2D Coulomb clusters in dusty plasmas
Ryuta Ichiki, Yuriy Ivanov, Matthias Wolter +2
The melting of 2D dust clusters caused by one additional particle in the lower layer has experimentally been observed to undergo a two-step transition, which divides the phase of t…
Production of a large diameter ECR plasma for plasma processing
Mayuko Koga, Yasuhiro Hishikawa, Hayato Tsuchiya +1
A large diameter plasma over 300 mm in diameter is produced by electron cyclotron resonance (ECR) discharges using a newly developed large diameter chamber of 400 mm in inner diame…
