A Multilayer Mirror/Monochromator for Dual-Energy Digital Subtraction Angiography

将设计一对大型多层膜反射器， 一个是在上面，一个是在下面， 用于双能量减影的碘边缘 同步辐射血管造影术。 镜面反射 将测量K边缘处的响应，并且性能 将在同步辐射血管造影光束线中进行分析， 二期工程。 制造参数的附加研究 将以优化反射率的观点进行。

A pair of large multilayer reflectors will be designed and fabricated, one to operate just above, and one just below the K- edge of iodine for application to dual-energy subtraction angiography using synchrotron radiation. The specular-angular responses at the K-edge will be measured, and the performance will be analyzed in a synchrotron angiography beam line, in this Phase II program. Additional studies of fabrication parameters will be carried out with a view of optimizing reflectivity.
