Abstract. Nowadays the achievements in accelerator physics allows us to operate with evergrowing energy of the particles beams. However, the increase of the beam energy requests new issues to be resolved. For instance, it becomes necessary to develop new techniques for beam diagnostics. One of the promising solutions for beam diagnostics is based on diffraction radiation (DR).In this work similar to the methods of bunch length measurement based on transition radiation, the longitudinal size of a bunch is retrieved from the dependence of the DR intensity on the wavelength of radiation. Such dependence is expressed by so-called form-factor, which in turn depends on the beam parameters. Influence of the beam divergence on the form-factor of a beam has been examined in this work.

“…Let us also note that, in contrast to TR, before the works [21,22], the DR has not been studied in the x-ray region. In [21], on the basis of some considerations given in [2], it has been shown that the XDR can be produced only for ideal, nonexisting beams.…”

“…Nevertheless, one of the purposes of this work is to show that, as in the case of soft CDR [19], apparently the x-ray DR can be observed as CXDR of MB beams when the intensity is again proportional toN 2 b , and the spectrum is very narrow. Indeed, using the above methods and formulas from [21,22] for incoherent XDR for the case when the well focused microbunched beam passes perpendicular to the strip radiator with thickness a and width b (see inset of Fig. 3), one obtains for CXDR…”

Theoretical and numerical results on angular and spectral distributions and total number of photons of several types of coherent radiation produced by microbunched beams passing through radiators are presented: coherent x-ray bremsstrahlung, x-ray transition, resonance transition, and diffraction radiations. The possibility of observation and application of these new types of radiation for the study of parameters of electron beam microbunching, which is important for the effectiveness of x-ray free electron lasers, is discussed.

Towards integrated tunable all-silicon free-electron light sources

Extracting light from silicon is a longstanding challenge in modern engineering and physics. While silicon has underpinned the past 70 years of electronics advancement, a facile tunable and efficient silicon-based light source remains elusive. Here, we experimentally demonstrate the generation of tunable radiation from a one-dimensional, all-silicon nanograting. Light is generated by the spontaneous emission from the interaction of these nanogratings with low-energy free electrons (2–20 keV) and is recorded in the wavelength range of 800–1600 nm, which includes the silicon transparency window. Tunable free-electron-based light generation from nanoscale silicon gratings with efficiencies approaching those from metallic gratings is demonstrated. We theoretically investigate the feasibility of a scalable, compact, all-silicon tunable light source comprised of a silicon Field Emitter Array integrated with a silicon nanograting that emits at telecommunication wavelengths. Our results reveal the prospects of a CMOS-compatible electrically-pumped silicon light source for possible applications in the mid-infrared and telecommunication wavelengths.
