Abstract:
Spin polarized beams are an essential tool in the study of nuclear physics using particle accelerators. Particle accelerators can produce spin polarized beams, but a technology is needed to continuously monitor, in real time and non-invasively, the beam's polarization direction and quality. Without this capability, there is no way to automate polarization quality optimization. The ring-coupled cavity resonator provides a mechanism to enhance the interaction between a cavity resonator and the spin of passing particles, and provides a method to determine and monitor, in real time and non-invasively, beam magnetization and longitudinal spin polarization direction and quality.
Abstract:
An EUV light source serves for generating a usable output beam of EUV illumination light for a projection exposure apparatus for projection lithography. The light source has an EUV generation device which generates an EUV raw output beam. The latter is circularly polarized. For the purposes of setting the polarization of the usable output beam and in respect of the polarization direction, a polarization setting device has a linearly polarizing effect on the raw output beam. This results in an EUV light source, which provides an improved output beam for a resolution-optimized illumination.
Abstract:
Examples are described related to nanostructures and assembling nanostructures. A fluid including nanostructures may be deposited onto a surface of a substrate. Optical beams may be directed towards a region of the surface of the substrate such that the optical beams overlap at a location within the region. Radiation pressure generated by the optical beams may effectively drive at least some of the nanostructures in the fluid towards the substrate. In this manner, the nanostructures may be assembled on the substrate.

Abstract:
A reflection surface 12 constituted by a transition metal having a core level absorption edge in the vicinity of a wavelength of a soft X-ray is formed on an inside of a vacuum vessel 14, and furthermore, there is provided a permanent magnet 13 for generating a magnetic field in a perpendicular direction to a longitudinal direction of the vacuum vessel 14 in a position of the reflection surface 12 by which the soft X-ray is to be reflected, and the soft X-ray to be linearly polarized light incident on the vacuum vessel 14 is reflected at plural times over the reflection surface 12 in a position where the magnetic field is applied in such a manner that magnetic scattering is increased by a resonant effect of a magnetic circular dichroism when the soft X-ray is reflected by the reflection surface 12. Thus, a great difference in a refractive index is made between circularly polarized counterclockwise light and circularly polarized clockwise light which constitute the linearly polarized light, and a phase difference between the circularly polarized counterclockwise light and the circularly polarized clockwise light is obtained at a time. Consequently, it is possible to reversibly convert the soft X-ray from the linearly polarized light into the circularly polarized light or from the circularly polarized light into the linearly polarized light by a reflection to be carried out at only several times.
Abstract:
In a system for isotope separation wherein a plasma of ions of one isotope type is created, method and apparatus for magnetically extracting the ions from the plasma without impairing the ionization selectivity and efficiency. In a particle flow of plural isotope types, radiant energy is applied to selectively excite and ionize ions of at least one isotope type without corresponding ionization of particles of other isotope types. A magnetic field is applied to divert the ions of the one isotope type sufficiently to permit separate collection of those ions without the other particle constituents of the flow. The system of the present invention balances the requirements for a high magnetic field to provide sufficient diversion before charge exchange with the requirement for a limited magnetic field to prevent interference with the selective ionization process due to Zeeman broadening of the isotope absorption lines.
Abstract:
A polarized beam of atoms is generated by forming a plurality of apertures of micron-sized diameter through a magnetically saturated monocrystalline material and passing in a partial vacuum a collimated beam of atoms through said apertures incident to the walls thereof. The monocrystalline material effects a charge-transfer reaction with the atomic beam to produce a polarized beam of atoms, the nuclei of which are subsequently polarized by hyperfine interaction in a weak external magnetic field.
Abstract:
The present invention relates to a method creating highly concentrated quantum entangled particles which can be embedded into substrates such that the particles, and therefore substrates they are embedded upon are remotely controllable. The invention includes streaming a beam of particles through a beam splitter and then applying a selected correlation system, such as NMR or supercooling, to the particles in order to align the particle spins. The particles are then released from the correlation system resulting in an unnaturally high saturation of concentrated quantum entangled particles on a macro scale. The particles and substrates are then in a salve-x relationship configuration and are therefore remotely controllable. Through stimulation and detection, changes in state may be observable in order to determine the level of concentration and remote control.
Abstract:
A mode converter for converting transverse electric modes into hybrid modes of type EH.sub.mn and including a circular waveguide provided with corrugations extending in a circumferential (azimuth) direction that become deeper toward its end and are continued in a subsequent helically outlined aperture antenna with constant depth. The emitted radiation is circularly polarized and, by the use of suitable reflectors for the emitted radiation, may be cause to be linearly polarized. The emitted radiation no longer has any sidelobes in the far field and its characteristic has a Gaussian profile over the azimuth angle.
Abstract:
Method and apparatus for highly polarizing a fast beam of particles by collisional pumping, including generating a fast beam of particles, and also generating a thick electron-spin-polarized medium positioned as a target for the beam. The target is made sufficiently thick to allow the beam to interact with the medium to produce collisional pumping whereby the beam becomes highly polarized.
