Tunable multilayer EUV/soft x-ray polarimeter
نویسنده
چکیده
A tunable polarimeter using multilayer interference coatings as both reflection polarizer and transmission phase retarder is described. The portable device bolts onto existing chambers and its rotation axis is precisely aligned to the beam. The upstream transmission phase retarder is tunable by varying its incidence angle, and the downstream polarizer is tunable by translating a laterally graded multilayer. These optical components allow an unambiguous determination of the polarization state of any collimated beam entering the device over at least the SO-800 eV range.

Space solar telescope in soft X-ray and EUV band
In this paper we have reviewed our achievements in soft X-ray and extreme ultraviolet (EUV) optics. Up to now, the research system of soft X-ray and EUV optics has been established, including light sources, detectors, calibrations, optical testing and machining of super smooth mirrors, and fabrications of multilayer film mirrors. Based on our achievements, we have developed two types of solar s...
متن کاملTunable Coherent Radiation in the Soft X-Ray and Extreme Ultraviolet Spectral Regions
Undulator radiation, generated by relativistic electrons traversing a periodic magnet structure, can provide a continuously tunable source of very bright and partially coherent radiation in the extreme ultraviolet (EUV), soft X-ray (SXR), and X-ray regions of the electromagnetic spectrum. Typically, 1–10 W are radiated within a 1=N relative spectral bandwidth, where N is of order 100. Monochrom...
متن کاملA Soft X-ray Polarimeter Designed for Broad-band X-ray Telescopes
A novel approach for measuring linear X-ray polarization over a broad-band using conventional imaging optics and cameras is described. A new type of high efficiency grating, called the critical angle transmission grating is used to disperse soft X-rays radially from the telescope axis. A set of multilayer-coated paraboloids re-image the dispersed X-rays to rings in the focal plane. The intensit...

Improving the eciency of soft X-ray and extreme ultraviolet (EUV) gratings by way of multilayer re¯ection coatings has been under investigation for many years. Here we present the fabrication and characterization of binary blazed gratings designed to operate in the 14 nm wavelength region. These binary gratings are stepped approximations to the ideal sawtooth blazed-grating pro®le and are fabr...

Cr/Sc multilayer systems can be used as near-normal incidence mirrors for the water window spectral range. It is shown that a detailed characterization of these multilayer systems with 400 bilayers of Cr and Sc, each with individual layer thicknesses <1 nm, is attainable by the combination of several analytical techniques. EUV and X-ray reflectance measurements, resonant EUV reflectance across ...
