Passage of neutrons through accelerating crystal and the acceleration effect
A. I. Frank, V. A. Bushuev, M. A. Zakharov +1
The problem of changing the energy of a neutron when it passes through an accelerating crystal under conditions close to the Bragg condition is considered. It is shown that, simila…
Performance of a cryo-cooled crystal monochromator illuminated by hard X-rays with MHz repetition rate at the European X-ray Free-Electron Laser
I. Petrov, U. Boesenberg, V. A. Bushuev +11
We present experimental data illustrating how heat load affects the performance of a cryogenically cooled monochromator under intense X-ray Free-Electron Laser pulses. The measurem…
Broadband quasi-PT Symmetry Sustained by Inhomogeneous Broadening of the Spectral Line
D. M. Tsvetkov, V. A. Bushuev, V. V. Konotop +1
It is shown that inhomogeneous broadening of the spectral line of active impurities may sustain simultaneously parity (P) and time (T) symmetries of a medium, in a finite range of…
Dynamical effects in Bragg coherent x-ray diffraction imaging on finite crystals
A. G. Shabalin, O. M. Yefanov, V. L. Nosik +2
We present simulations of Bragg Coherent X-ray Diffractive Imaging (CXDI) data from finite crystals in the frame of the dynamical theory of x-ray diffraction. The developed approac…
Spectroscopy of ultracold neutrons using diffraction by a moving grating
G. V. Kulin, A. I. Frank, S. V. Goryunov +7
Spectra of ultracold neutrons that appeared in experiments on neutron diffraction by a moving grating were measured using the time-of-flight Fourier spectrometer. Diffraction lines…
Dynamical theory of diffraction on moving grating
V. A. Bushuev, A. I. Frank, G. V. Kulin
In the framework of the approximation of slowly varying amplitudes a multiwave dynamical theory of neutron diffraction on a moving phase grating was developed. The influence of the…
Spectrometer for new gravitational experiment with UCN
G. V. Kulin, A. I. Frank, S. V. Goryunov +5
We describe an experimental installation for a new test of the weak equivalence principle for neutron. The device is a sensitive gravitational spectrometer for ultra-cold neutrons…
