Spectrum of coherent VUV radiation generated by 5.7 MeV electrons in a multilayer X-ray mirror

“…The measured spectral line width is an experimental evidence of the separately observed PXR and DTR contributions, since the width of the PXR spectral line should be several times narrower than that of the DTR (figures 4 and 5). The DTR and PXR spectra can be studied using another multilayer structure as a spectrometer [13][14][15][16]. The width of the spectral line can be found experimentally by measuring the width of the rocking curve -the dependence of the radiation output on the tilt angle of the multilayer structure.…”

Characteristics Of Transition Radiation In The X-Ray Spectral Region

“…The theory of transition radiation was correctly predicted more than forty years ago, and has been a topic of continued study since that time. 3 Application of transition radiation has been hampered by the CO.-IL 1 Icated, multiparameter nature of the theories, nakinq it difficult t -understand how transition radiation might apply to a given sitJatin*. This difficulty can now be avoided with relatively simple computer calculations of transition radiation emission distributions.…”

“…The specific equations used for the calculations will not be presented; for a more thorough discussion of the theory, the reader is referred to any of a number of appropriate references. [1][2][3][4][5][6][7][8][9] The format ion length…”
