We have investigated the behavior of a small number of charged fine particles under Coulomb interactions in an AC trap. There is a transition from ballistic to diffusive motion in the mean square displacement of the angle, θ, for a single charged fi

For the purpose of tritium removal from carbon co-deposits on plasma-facing material of fusion device, pulsed-laser induced desorption of hydrogen from co-deposits on JT-60 open-divertor tile has been investigated. The fundamental (1064 nm) and fourt

We proposed a new method for measuring plasma energy using superconducting helical field coil (HFC) signals. The change in HFC flux is experimentally confirmed due to the increase in plasma energy. The VMEC-DIAGNO equilibrium analysis code clarified

Characterization of a compact, high density, and uniform rf line-plasma source has been investigated. Plasma production is conducted in a rectangular discharge chamber (200×100×20 mm3) with a pair of permanent magnets placed on top and bottom of th

Helicon-wave sustained (HW) and slow-wave sustained (SW) discharges are studied in a whistler- or helicon-wave range of frequency using high-frequency (13.56 MHz) and very-high-frequency (50 and 144 MHz) bands of rf. For 13.56 and 50 MHz, in addition

High-density plasma production by helicon waves in a simple torus has been investigated. The measured plasma density np versus external magnetic field B0 peaks at a condition close to the lower-hybrid resonance in H2, D2, and He. Three density region
