Autor: Tokihiko Tokuzawa, Shigeru Inagaki, Michiaki Inomoto, Akira Ejiri, Tatsuhiro Nasu, Toru Ii Tsujimura, Katsumi Ida
Publikováno v: Applied Sciences, Vol 12, Iss 9, p 4744 (2022)
A new Doppler radar using millimeter-waves in the Ka-band, named the “dual-comb Doppler reflectometer”, has been developed to measure the turbulence intensity and its velocity in high-temperature plasmas. For the realization of a fusion power gen

Reconstruction of plasma shape and eddy current profile based on modified cauchy condition surface method in merging spherical tokamak
Autor: Tomohiko Ushiki, Masafumi Itagaki, Michiaki Inomoto
Publikováno v: Fusion engineering and design. 122:35-41
The spherical tokamak merging start-up is one of the central solenoid-free start-up method. For controlling the merging actively, it is essential to identify the plasma shapes during the merging process. In the present work, the modified Cauchy condi

Development of new experimental setup focusing on long-pulse magnetic reconnection by using rotating magnetic field technique
Autor: Michiaki Inomoto, Ryoma Yanai, Y. Takahata
Publikováno v: The Review of scientific instruments. 89(10)
A new closed-type experimental setup to achieve a long-pulse magnetic reconnection in weakly ionized plasmas was developed by using a rotating magnetic field (RMF) technique. The experimental setup has a cylindrical vacuum vessel in which two sets of

Basic Study of Two-Dimensional Thomson Scattering Measurement by Multiple Reflections and Time-of-Flight of Laser Beam
Autor: Michiaki Inomoto, Raita Kotani, Shingo Ito, Kazumichi Narihara, Yasushi Ono, Hisashi Sakamoto
Publikováno v: Electronics and Communications in Japan. 97:1-7
SUMMARY A novel two-dimensional Thomson scattering (TS) measurement system has been developed by adopting the time-of-flight (TOF) difference in the signals scattered from three parallel laser beams formed by multiple reflections. New ideas are: (1)

Low-Frequency Magnetic Fluctuation Measurement during Magnetic Reconnection in Counter-Helicity Plasma Merging Experiment
Autor: Hiroshi Tanabe, Akihiro Kuwahata, Shingo Ito, Michiaki Inomoto, Yasushi Ono
Publikováno v: Electrical Engineering in Japan. 187:1-8
SUMMARY Magnetic fluctuations at a frequency lower than the local ion cyclotron frequency have been observed in association with magnetic reconnection events in a TS-3 plasma merging device. Counter-helicity merging of spheromaks provides significant
