Abstract
Description
本発明は、一般には、X線管の分野に関し、より詳細には、分析機器に使用される望ましい波長におけるX線の高出力密度生成に関する。
X線管において、高エネルギー電子ビーム(典型的には、10−100keV)は、ターゲット材料に作用してX線放射を励起する。X線回析など、分析アプリケーションに使用されるX線管の場合、管は、特定の波長で特性放射線を作り出すように最適化される。そのようなアプリケーションに使用される最も一般的なX線管は、クロム、コバルト、銅、モリブデン、銀ロジウムまたはタングステンで構成されるターゲットアノードを組み込む。アノード材料の選択は、本件の分析アプリケーションにとって望ましいX線波長に基づく。
