1 3 A ug 2 00 1 Superradiance in volume diffraction grating ⋆
نویسنده
چکیده
To simulate VFEL operation the superradiance from a short electron pulse moving in a volume diffraction grating is studied. It is supposed that Bragg condition for emitted photons is fulfilled and dynamical diffraction takes place. Spectral-angular distributions for transmitted and diffracted waves are derived. It is shown that the optimal geometry for superradiance exists and it is determined by the energy and transverse size of electron beam.

Atom-surface interactions can significantly modify the intensity and phase of atom de Broglie waves diffracted by a silicon nitride grating. This affects the operation of a material grating as a coherent beam splitter. The phase shift induced by diffraction is measured by comparing the relative phases of serveral interfering paths in a Mach-Zehnder Na atom interferometer formed by three materia...

Results on soft and hard diffraction obtained by the CDF Collaboration at the Fermilab Tevatron p̄p Collider are reviewed with emphasis on aspects of the data that point to the underlying QCD mechanism for diffraction. The results are interpreted in terms of a phenomenological approach in which diffraction is due to an exchange of low-x partons subject to color constraints.

We present results from cryogenic tests of a Volume-Phase Holographic (VPH) grating at 200 K measured at near-infrared wavelengths. The aims of these tests were to see whether the diffraction efficiency and angular dispersion of a VPH grating are significantly different at a low temperature from those at a room temperature, and to see how many cooling and heating cycles the grating can withstan...

A simple model of 1D structure based on a Fibonacci sequence with variable atomic spacings is proposed. The model allows for observation of the continuous transition between periodic and non-periodic diffraction patterns. The diffraction patterns are calculated analytically both using “cut and project” and “average unit cell” methods, taking advantage of the physical space properties of the str...
متن کاملThe dielectric lamellar diffraction grating
A rigorous modal theory describing the diffraction properties of a dielectric lamellar grating is presented . The numerical implementation is shown to be suited to modelling the behaviour of high refractive index gratings . This suggests that an approach of this type may be successfully applied to the problem of lossy metallic lamellar gratings . 1 . Introduction The problem of diffraction by a...
