摘要：

We developed a hybrid X-ray focusing optics, which consisted of a polycapillary X-ray lens (PC(L) and a tungsten conical pinhole (WCP) for micro X-ray fluorescence (mu-XRF) analysis. A single PCXL produced an X-ray micro beam with a spot size of 12 mu m. We developed a WCP by using a laser-ablation technique with an input diameter of 39 mu m, an output diameter of 2.5 mu m, and a thickness of 0.5 mm in a conical shape. This hybrid X-ray optics gave a small spot size of 2.8 mu m with a small divergent angle of 12 mrad. (C) 2013 Elsevier B.V. All rights reserved.
