Introduction,The concept of a crystalline undulator as a source of high-energy electromagnetic radiation, both spontaneous and stimulated, is formulated. The distinguishing features of CU and of its radiation, the feasibility of CU and the methods of preparation of periodically bent crystalline structures are discussed in general terms.让你明白 发表于 2025-3-23 19:50:36
Conclusion,The achievements in theoretical, technological and experimental investigations of various phenomena associated with the crystalline undulator and the radiation formed in it are summarized. The perspectives of further developments in this field are discussed.COM 发表于 2025-3-24 01:59:45

Polyelectrolytes and their Applicationslated. The influence of parasitic effects, such as dechanneling phenomenon, the photon attenuation and radiative energy losses on the properties of CUR are analyzed both analytically and numerically. Historical survey of the evolution of the CU-related ideas is given.Forehead-Lift 发表于 2025-3-24 12:47:30

Polyimides for semiconductor applications,iction due to the smallness of the dechanneling length, the CU must operate in the regime of higher beam energies than a positron-based one does. However, the operation of electron-based CU is also feasible for the low-energy electron beams (below 1 GeV). An algorithm of a new classical Monte Carlodiabetes 发表于 2025-3-24 19:59:17

Polymeric Biomaterials in Medica L Systemsrgies, .–. keV, is inaccessible in conventional FELs. Three different schemes of achieving the lasing effect are presented: (a) a gamma-amplifier based on the use of a single CU; (b) a gamma-klystron which utilizes the sequence of two (or more) CUs; (c) a Crystalline Undulator Laser. We demonstrate,
