Ultra soft X-ray Microbeam: optical analysis and intensity measurements

摘要

In this work, optical analysis and intensity measurements of the Ultra Soft x-ray microbeam (100 eV–1 keV) are presented. X-ray emission at 500 eV are generated from a plasma produced by focusing Nd-YAG laser beam on the Yttrium target. In particular, we will report the study of x-ray intensity and the measurement of focal spot dimension. Moreover, the software/ hardware control of sample holder position and the alignment of biological sample to the microbeam will be described.
