Development of a Millimeter-Wave Beam Position and Profile Monitor for Transmission Efficiency Improvement in an ECRH System

EPJ Web of Conferences, 2015
In a high power Electron Cyclotron Resonance Heating (ECRH) system, a long-distance and low-loss transmission system is required to realize effective heating of nuclear fusion-relevant plasmas.

An assessment of the evaporation and condensation phenomena of lithium during the operation of a Li(d,xn) fusion relevant neutron source

Heliyon, 2016
The flowing lithium target of a Li(d,xn) fusion relevant neutron source must evacuate the deuteron beam power and generate in a stable manner a flux of neutrons with a broad peak at 14 MeV capable to cause similar phenomena as would undergo the ...

Direct measurement of refracted trajectory of transmitting electron cyclotron beam through plasma on the Large Helical Device

EPJ Web of Conferences, 2015
The electron-cyclotron (EC) -beam refraction due to the presence of plasma was investigated in the Large Helical Device. The transmitted-EC-beam measurement system was constructed and the beam pattern on the opposite side of the irradiated surface was ...

D-Fusion: A Distinctive Fusion Calculus [PDF]

, 2004
We study the relative expressive power of Fusion and pi-calculus. Fusion is commonly regarded as a generalisation of pi-calculus. Actually, we prove that there is no uniform fully abstract embedding of pi-calculus into Fusion. This fact motivates the introduction of a new calculus, D-Fusion, with two binders, λ and ν.

Recent result of gyrotron operation in NIFS

EPJ Web of Conferences, 2015
In the last Large Helical Device (LHD) experimental campaign, a 154GHz gyrotron which had been conditioned to generate 1 MW/2 s, 0.5 MW/CW was installed for LHD experiments.

Infection Control Practices for Vascular Access Management in Hemodialysis: Results From a Nationwide Survey of Japanese National University Hospitals

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Bloodstream infections due to repeated vascular access (VA) puncture and circuit connections remain major concerns in hemodialysis. Therefore, we examined current practices for glove, disinfectant, and personal protective equipment (PPE) use according to VA type in national university hospitals in Japan.

Workshop at Data and Planning Center of NIFS in 2003 "Assesment of Fusion R&D" - The Critical Issues of Demonstration Fusion Reactor - [PDF]

, 2004
実証炉を構想しそれに至る課題を整理することは、核融合研究開発の現状を評価するうえで最も適切な作業のひとつと考えた。磁場閉じ込めと慣性閉じ込め核融合に共通な課題は経済性の改善である。また、磁場閉じ込めではトカマクもヘリカルも将来性のあるダイバータの開発は共通である。 経済性に関しては先進トカマクや高速点火方式のレーザ慣性核融合の提案が出てきている。さらにダイバータに関しては可動型や外置き型の研究が進められている。これらの要約は添付した。In order to asses the fusion ...
