Description
本出願は、2013年9月17日に出願された、Tomas Plettner及びJohn Gerlingに対する所有者共通の同時係属米国仮特許出願第61/878,609号、名称「ELECTRO−OPTIC ELECTRON BEAM MONITOR」の非仮特許出願であり、その優先権の利益を主張し、その全開示は、参照により本明細書に組み込まれる。
連続波(CW)プローブビームを使用する走査型電子顕微鏡(または同様のツール)用の電気光学(EO)検出器は、基本的に、EO効果を使用して単一の電子を検出しようとするものである。例えば、1keVのナノアンペア電子ビーム内の電子は、約3mm離間している。検出器が、荷電粒子ビームの方向に約1mmの長さを有するEO材料を含む場合、所与の時間において約1個のみの電子が検出器を通過している。
