Design and analysis of reflective line focus systems for X-ray laser experiments

Based on the three-dimensional ray tracing and aberration calculations,the off-axis mirror line focus system used in SERC Rutherford Appleton Laboratory is analyzed.Then,two types of novel reflective line focus geometry for X-ray laser experi-ments,namely,the reflective wedge array and conical lens array systems,are first pro-posed and illustrated with numerical examples.Finally,the results are compared and discussed.
