WebPart of the NATO Science Series book series (NAII,volume 49) Abstract A simple method of obtaining crystalline undulators (CU) is proposed using the curvature arising when a very thin layer of Ge x Si 1-x is epitaxially grown on a thin Si substrate. WebDec 21, 2001 · One possibility to couple acoustic waves to the crystal is to place a piezo sample atop the crystal and to use radio frequencies to excite oscillations. The usage of a statically and periodically bent crystal was discussed in Ref. [3]. The idea is to construct a crystalline undulator based on graded composition strained layers.

If ultrarelativistic charged particles channel through such a … WebOct 11, 2002 · Abstract It is proposed to create crystalline undulators (CU) with periodically deformed crystallographic planes using the curvature due to the alternating stresses arising when strips of very thin films are grown on a thin substrate.
WebApr 24, 2024 · In particular, a crystalline undulator consists in a periodically bent crystal in which channeled electrons or positrons follow the bending of the crystalline planes, thus generating electromagnetic radiation in analogy with standard magnetic undulators. State-of-the-art magnetic undulators can be built with a period of no less than a few cm. WebFeb 7, 2007 · A crystal mounting method and an alignment procedure have been developed for simple and reliable installation. From the quantitative evaluation of the performance, it was found that the cooling capability is sufficient even for an incident power of 370 W (power density of 450 W/mm2).
WebAug 15, 2013 · A ”first principle” approach to simulation of crystal undulator radiation is described and applied to both electron and positron cases. We suggest the possibility to considerably improve the crystal undulator functioning by increasing the positron capture into deep channeling states using a crystal cut or a buried oxide layer.
