摘要
A table-top soft x-ray microscope based on a long-term stable and nearly debris-free laser plasma from a pulsed nitrogen gas jet target is presented. The microscope operates in the "water window" region at 2.88 nm wavelength. The emitted soft x-ray radiation is focused by an ellipsoidal condenser mirror into the object plane and a sample is imaged using a Fresnel zone plate onto a CCD camera. The spatial resolution of the microscope is about 50 nm demonstrated for a Siemens star test pattern.
