Abstract:
A multi-energy imaging system and method for selectively generating high-energy X-rays and low-energy X-ray beams are described. A pair of optic devices are used, one optic device being formed to emit high X-ray energies and the other optic device being formed to emit low X-ray energies. A selective filtering mechanism is used to filter the high X-ray energies from the low X-ray energies. The optic devices have at least a first solid phase layer having a first index of refraction with a first photon transmission property and a second solid phase layer having a second index of refraction with a second photon transmission property. The first and second layers are conformal to each other.
Abstract:
Optical set-up displaying X-ray radiation with wavelength ? consists of monocrystal (1) with atomic planes (2) in parallel with optical axis (3). The mutual distance of the atomic planes in resting state without the force is d0. Cross section (S) of the monocrystal (1) is variable. With respect to the optical axis (3) the farther and/or closer side of monocrystal (1), which is orthogonal to this optical axis (3), is equipped with a device creating and maintaining pull or push force (F) in direction orthogonal to atomic planes (2) of such monocrystal (1).

Die Erfindung betrifft auch Verfahren zur Herstellung der modifizierten Multikanalstruktur sowie deren Verwendung.
Abstract:
A patterning device for a photolithographic apparatus is used to form a patterned radiation beam, by imparting a cross-sectional pattern to the radiation beam during reflection from the patterning device. The patterning device comprises a layer of phase-change material that is capable of locally undergoing an induced structural phase change into respective ones of a plurality of stable and/or metastable states. Furthermore, the patterning device comprises a radiation reflective structure with periodically arranged layers adjacent to the layer of phase-change material. The radiation reflective structures do not partake in the phase changes. By locally changing the phase of the phase-change material, the reflectivity of the whole structure is modified, for example due to thickness changes in the layer of phase-change material that lead to destructive interference of different components of the reflected light or due to changes in surface roughness of the radiation reflective structure.

Abstract:
Provided are an X-ray mirror master mandrel and a method of replicating an X-ray mirror using the X-ray mirror master mandrel. The X-ray mirror master mandrel includes a jig and a master mandrel. The jig is fixed to a front end of a spindle of an ultra-precision machining apparatus using first coupling members. The master mandrel includes a fixing end, a neck, a mirror portion, and an interface. The fixing end is fixed to a front end of the jig using second coupling members. The neck extends from a front end of the fixing end. The mirror portion extends from a front end of the neck. The interface is formed due to a difference between a diameter of the neck and a diameter of the mirror portion. The diameter of the mirror portion is greater than the diameter of the neck.
Abstract:
ABSTRACT There are provided a substrate with a reflective layer and an EUV mask blank, which can prevent particles from adhering to a surface of the reflective layer or an absorbing layer, or into a reflective layer or an absorbing layer during formation thereof by eliminating electrical connection between a film formed on a front surface of the substrate and a film formed on a rear surface of the substrate. A substrate with a reflective layer, which is usable to fabricate a reflective mask blank for EUV lithography, comprising a chucking layer formed on a rear surface opposite a surface with the reflective layer formed thereon, the chucking layer serving to chuck and support the substrate by an electrostatic chuck, wherein the reflective layer has no electrical connection to the chucking layer.
