A novel x-ray polarimeter based on hexagonal crystal, for application to thermonuclear fusion experiments

E O Baronova, M M Stepanenko2003年Plasma Physics and Controlled FusionIF 2.2出版社

A correct estimation of plasma parameters in fusion experiments cannot be done unless the role of polarization of x-ray line emission is recognized.An x-ray polarimeter is presented, based on single hexagonal crystal. The polarimeter selects two polarized components simultaneously. Simple analytical formulae are suggested to determine Bragg angle for analysed x-rays and for the directions of reflected polarized components. The polarimeter is expected to be especially useful to study polarization of x-rays emitted from plasmas with thermonuclear parameters.

核融合実験におけるプラズマパラメータの正確な推定は、X線輝線の偏光の役割を認識しない限り行うことはできない。単結晶六方晶に基づくX線偏光計が提示される。この偏光計は、2つの偏光成分を同時に選択する。解析X線に対するブラッグ角と、偏光した反射成分の方向を決定するための簡単な解析式が提案される。この偏光計は、熱核パラメータを有するプラズマから放射されるX線の偏光を研究するのに特に有用であると期待される。
