Experimental results on hard x-ray energy emitted by a low-energy plasma focus device: a radiographic image analysis

Marcelo Zambra, Patricio Silva, Cristian Pavez, Denisse Pasten, José Moreno, Leopoldo Soto2009年Plasma Physics and Controlled FusionIF 2.2出版社

The PF-400J plasma focus device (400 J of energy) was studied in a similar way to a pulsed source of high-energy x-ray radiation. High-sensitivity fast-response commercial radiographic film and different metal filter array combinations were used to study the energy of the proper emitted x-ray. The effective energy of the hard x-ray radiation is studied and discussed in terms of its effective mean attenuation with the penetration distance on different metallic samples when the x-ray pulsed beam is supposed monoenergetic. These results were then used to assess the energetic properties of the pulsed radiation when different x-ray film–filter array combinations were irradiated between tens to almost 160 effective pulses of x-ray coming from the PF-400J device.

PF-400Jプラズマフォーカス装置(400Jのエネルギー)は、高エネルギーX線放射のパルス源として同様の方法で研究された。高感度の高速応答型商用放射線写真フィルムと異なる金属フィルターアレイの組み合わせを用いて、適切に放出されたX線のエネルギーを調査した。硬X線放射の実効エネルギーは、X線パルスビームが単色であると仮定した場合の、異なる金属試料における透過距離に伴う実効平均減衰の観点から研究・考察された。これらの結果は、PF-400J装置から放出される約数十回からほぼ160回の実効X線パルスを照射した際の、異なるX線フィルム–フィルターアレイの組み合わせにおけるパルス放射のエネルギー特性を評価するために使用された。
