Measurement of the time dependent neutron energy spectrum in the 'DENA' plasma focus device

M Abdollahzadeh, S M Sadat kiai, A R Babazadeh2008年Plasma Physics and Controlled FusionIF 2.2出版社

An extended time of flight method is used to determine the time dependent neutron energy spectrum in the Filippove type 'Dena' plasma focus (90 kJ, 25 kV, 288 µF), filled with deuterium gas. An array of 5 detectors containing NE-102 plastic scintillators+photomultipliers is used. The number and position of the detectors are determined by a Monte Carlo program and the MCNP code. This paper briefly describes the simulation method and presents the experimental measurements and their results. The mechanisms of neutron production (thermonuclear and non-thermonuclear) and their time variations are discussed.

飛行時間法の拡張を用いて、重水素ガスを充填したフィリポフ型『デナ』プラズマフォーカス(90 kJ、25 kV、288 µF)における時間依存中性子スペクトルを決定した。NE-102プラスチックシンチレータ+光電子増倍管からなる5基の検出器アレイを使用した。検出器の数と位置は、モンテカルロプログラムおよびMCNPコードによって決定した。本論文では、シミュレーション手法を簡潔に説明し、実験測定とその結果を示す。また、中性子生成機構(熱核的および非熱核的)とその時間的変動について考察する。
