Total spectrum of photon emission by an ultra - relativistic positron channelling in a periodically bent crystal
We present the results of numerical calculations of the channelling and undulator radiation generated by an ultra-relativistic positron channelling along a crystal plane, which is periodically bent. The bending might be due either to the propagation of a transverse acoustic wave through the crystal, or due to the static strain as it occurs in superlattices. The periodically bent crystal serves ...
متن کاملSpontaneous and stimulated undulator radiation by an ultra-relativistic positron channeling in a periodically bent crystal ?,??
We discuss the radiation generated by positrons channeling in a crystalline undulator. The undulator is produced by periodically bending a single crystal with an amplitude much larger than the interplanar spacing. Different approaches for bending the crystal are described and the restrictions on the parameters of the bending are discussed. We also present numeric calculations of the spontaneous...
متن کاملThe influence of the dechanneling process on the photon emission by an ultra - relativistic positron channeling in a periodically bent crystal . ‡ Andrei
We investigate, both analytically and numerically, the influence of the dechanneling process on the parameters of undulator radiation generated by ultrarelativistic positron channelling along a crystal plane, which is periodically bent. The bending might be due either to the propagation of a transverse acoustic wave through the crystal, or due to the static strain as it occurs in superlattices....
متن کاملExperimental evidence of planar channeling in a periodically bent crystal
The usage of a crystalline undulator (CU) has been identified as a promising solution for generating powerful and monochromatic γ -rays. A CU was fabricated at Sensors and Semiconductors Lab (SSL) through the grooving method, i.e., by the manufacturing of a series of periodical grooves on the major surfaces of a crystal. The CU was extensively characterized both morphologically via optical inte...
متن کاملUltra- Relativistic Solitons with Opposing Behaviors in Photon Gas Plasma
We have studied the formation of relativistic solitary waves due to nonlinearinteraction of strong electromagnetic wave with the plasma wave. Here, our plasma isrelativistic both in temperature and in streaming speed. A set of equations consisting ofscalar and vector potentials together with a third order equation for the enthalpy inphoton gas plasma is obtained analytic...
