Crystalline Micro Undulator

On the mechanical behaviour of a crystalline undulator

“…In the present work a periodic deflection of a crystalline substrate is obtained patterning its surfaces with alternate strips [9] through a low pressure chemical vapour deposition (LPCVD) technique. The advantages concerning this method have been reported previously [14].…”

Accelerator Tests of Crystal Undulators

“…Later on, in 1984, Ikezi et al 6 proposed a Si 1-x Ge x /Si graded composition lattice with periodical modulation of Ge content x. More recently, Avakian et al 11 suggested to apply a periodic surface strain on crystal wafer. These ideas have been theoretically developed 4-11 but they are still pending realization.…”

“…Typically, at the modern accelerators the period of undulator in the synchrotron light sources is a few centimeters 1 . With a strong worldwide attention to novel sources of radiation, there has been broad interest [2][3][4][5][6][7][8][9][10][11] to compact undulators based on channeling in crystals, where a strong periodic electric field exists by nature. The crystalline undulators with periodically deformed crystallographic planes offer electromagnetic fields in the order of 1000 Tesla and could provide a period L in sub-millimeter range.…”

Radiation of relativistic particles for quasiperiodic motion in a transparent medium

“…At the present time such power sources of x-rays as undulators [1] are widely used in various fields of science. In a number of papers [2,3,4,5,6,7,8,9], with the aim of increasing of the energy of emitted photons, the crystal undulator was considered. The recent paper [10] contains a rather complete list of references related to various problem of crystal undulators [11].…”
