JOURNAL FREE ACCESSThe High Field Laboratory for Superconducting Materials (HFLSM) was established in April 1981 in the Research Institute for Iron, Steel and Other Metals, Tohoku University, for the developmental research on superconducting materials which would be used for superconducting magnets for plasma confinements in fusion reactors. Its main facilities consist of three hybrid magnets up to 30 T with inner bores of 32 to 52 mm. Cooperative research programs are under way in a nation-wide scale. Design concepts of hybrid magnets are discussed in detail. The present status of our hybrid magnet system is also described. The current situation of hybrid magnets in the world is briefly reviewed.View full abstractDownload PDF (2566K) -
Toshiatsu ODA1985 Volume 53 Issue 2 Pages 123-134

Released on J-STAGE: March 04, 2011
JOURNAL FREE ACCESSA brief review is given of spectroscopic measurements by using laser-induced fluorescence technique in various plasmas. Observations of metal impurity behaviors in the edge-region of magnetically confined plasmas, and new methods for measuring local electron density, fluctuating electric fields in plasmas, and the Doppler profile of impurity atoms by a single laser shot are described.View full abstractDownload PDF (908K) -

JOURNAL FREE ACCESSIntense pulsed ion beams are extracted from magnetically insulated diodes, whose anodes are cooled with liquid nitrogen or helium. The lowest temperature of the anodes is about 5 K, and H2 ices are produced on the anode surfaces. H+ beams of high purity are extracted with good reproducibility. Another kinds of beams (Ar+, N+, D+) are produced also with the corresponding ices. Performances of the diodes and the beam characteristics are described briefly in this report.View full abstractDownload PDF (2201K) -

JOURNAL FREE ACCESSTechnological troubles and new approaches in a pulse-power machine : LIMAYI as a relativistic electron and light ion beam generator are reported. Liquid Fron-113 is successfully tested as insulator of the Marx generator for the first case. We develop a new type of a SF6 spark gap switch for the Marx generator.View full abstractDownload PDF (828K) -
Tihiro Ohkawa1985 Volume 53 Issue 2 Pages 161-168
Published: February 20, 1985
Released on J-STAGE: March 04, 2011
JOURNAL FREE ACCESSA new method of impurity control in toroidal devices is proposed. Density inhomogeneity on flux surfaces produced by beam injection or rf heating creates a poloidal electric field. The resultant impurity ion distribution and orbit leads to the reversal of the impurity inflow.View full abstractDownload PDF (413K) -
