    • A method to determine a concentration of a target element in a sample is provide. The method comprises (i) positioning a sample containing a target element with respect to a reference material containing a reference element, (ii) simultaneously irradiating the sample and the reference material with Bremsstrahlung X-rays to thereby produce activated nuclei in the target element and to produce activated nuclei in the reference element, (iii) detecting deactivation gamma-rays' from the irradiated sample and deactivation gamma-rays from the irradiated reference material, (iv) determining a first number of detected deactivation gamma-rays from the irradiated sample and a second number of detected deactivation gamma-rays from the reference material, and (v) determining the concentration of the target element in the sample by first normalising the first number of detected deactivation gamma-rays from the irradiated sample by the second number of detected deactivation gamma-rays from the reference material. The variation of the reference element to target element cross section ratio over a range of electron beam energies is less than a predetermined measurement accuracy.
    • 提供了确定样品中目标元素浓度的方法。 该方法包括(i)相对于包含参考元件的参考材料定位包含目标元素的样品,(ii)用Bre致辐射X射线同时照射样品和参考物质,从而在目标元素中产生活化的核, 在参考元件中产生活化的核,(iii)从照射的样品中检测去激活的γ射线,以及从照射的参考物质中去激活γ射线,(iv)从被照射样品中确定检测到的去激活γ射线的第一数量 和来自所述参考物质的检测到的去激活γ射线的第二数量,以及(v)通过首先将来自被照射的样品的检测到的去激活γ射线的第一数量归一化来确定样品中的目标元素的浓度第二数量 检测到来自参考物质​​的失活γ射线。 参考元件与目标元件截面比在电子束能量范围内的变化小于预定的测量精度。

    • Methods, apparatuses, and systems for slice and view processing of samples with dual beam systems. The slice and view processing includes exposing a vertical wall of a trench formed in a sample surface; capturing a first image of the wall by interrogating the wall with an interrogating beam while the wall is at a first orientation relative to the beam; capturing a second image of the wall by interrogating the wall with the beam while the wall is at a second orientation relative to the beam, wherein first distances in the first image between a reference point and surface points on the wall are different than second distances in the second image between the reference point and the surface points; determining elevations of the surface points using the first distances and the second distances; and fitting a curve to topography of the wall using the elevations.
