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.

A magnetic material observation method in accordance with the present invention includes: an irradiating step including irradiating a region of a sample with an excitation beam and thereby allowing a magnetic element contained in the sample to radiate a characteristic X-ray; a detecting step including detecting intensities of a right-handed circularly polarized component and a left-handed circularly polarized component contained in the characteristic X-ray; and a calculating step including calculating the difference between the intensity of the right-handed circularly polarized component and the intensity of the left-handed circularly polarized component. Reference to such a difference enables precise measurement of the direction or magnitude of magnetization without strict limitations as to the sample.

In a general aspect, a collimator system is described. In some aspects, a neutron beam collimation method includes receiving a neutron beam from a neutron source; polarizing the neutron beam using a polarizer, and obtaining a collimated neutron beam from the polarized neutron beam. The neutron beam generated by the neutron source has a first beam divergence and includes a plurality of neutrons. The collimated neutron beam has a second beam divergence that is less than the first beam divergence. Obtaining the collimated neutron beam includes mapping transverse momentum of each respective neutron, of the plurality of neutrons, onto a polarization degree of freedom of the respective neutron by applying a sequence of phase shift gradients to the polarized neutron beam, and after applying the sequence of phase shift gradients, passing the polarized neutron beam through an analyzer.

The present invention relates to a detector arrangement for an X-ray phase contrast system (5), the detector arrangement (1) comprising: a scintillator (11); an optical grating (12); and a detector (13); wherein the optical grating (12) is arranged between the scintillator (11) and the detector (13); wherein the scintillator (11) converts X-ray radiation (2) into optical radiation (3); wherein the IN optical grating (12) is configured to be an analyzer grating being adapted to a phase-grating (21) of an X-ray phase contrast system (5); wherein the optical path between the optical grating (12) and the scintillator (11) is free of focussing elements for optical radiation. The present invention further relates to a method (100) for performing X-ray phase contrast imaging with a detector arrangement (1) mentioned above. The invention avoids the use of an X-ray absorption grating as G2 grating in an X-ray phase contrast interferometer system.

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.

A method and means to produce a force for propulsion comprises a source of free electrons and a means to produce pseudoelectrons; whereas, a gravitating body such as the Earth provides a repulsive fifth force on the pseudoelectrons. Pseudoelectrons are produced by absorption of high-energy photons by free electrons or by angular momentum exchange between polarized relativistic free electrons and a collision partner such as H3+. The free electrons to undergo transitions to pseudoelectron states may be first formed in the ground spin state. The pseudoelectrons experience a fifth force (F2) away from the Earth and move upward (away from the Earth).

Preparing a metrologically-relevant entangled state includes: providing a plurality of atoms in a regular lattice, wherein each atom is in an initial quantum state of a first state in a ground state manifold; initializing a central atom in the regular lattice to a (|0+|1)/?2 state while all other atoms remain in the first state |0 as remaining atoms; and proceeding, starting with the central atom, to propagate preparation of Greenberger-Horne-Zeilinger (GHZ) states in a nonlinear progression by increasing a number of GHZ states in each iteration through the remaining atoms in a recursive manner, to produce an intermediate GHZ state, such that the intermediate GHZ state acts as an initial GHZ state for a next iteration, until a final GHZ state is formed to prepare the metrologically-relevant entangled state of the atoms.
