“…(The Smith-Purcell effect for a single grating with these characteristics has been discussed in Ref. [14].) Although this model is clearly an oversimplification, its main features do not depend on the choice of the perturbation structure: The existence of diffraction radiation is due to the excitation of propagating modes by evanescent waves and is independent of the particular mechanism by which the propagating modes are excited.…”

We show that if the visible universe is a membrane embedded in a higher-dimensional space, particles in uniform motion radiate gravitational waves because of spacetime lumpiness. This phenomenon is analogous to the electromagnetic diffraction radiation of a charge moving near to a metallic grating. In the gravitational case, the role of the metallic grating is played by the inhomogeneities of the extra-dimensional space, such as a hidden brane. We derive a general formula for gravitational diffraction radiation and apply it to a higher-dimensional scenario with flat compact extra dimensions. Gravitational diffraction radiation may carry away a significant portion of the particle's initial energy. This allows to set stringent limits on the scale of brane perturbations. Physical effects of gravitational diffraction radiation are briefly discussed.

“…The first of our two novel bunch-length diagnostics is based on coherent SmithPurcell radiation (SPR) [13,14,15,16,17]. When an electron beam traverses close to the surface of a metallic diffraction grating, SPR is emitted (Figure 1 …”

This is the final report of a three-year, Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). The purpose of this LDRD project was to develop new, inexpensive, simple electron beam bunch-length diagnostics with resolutions below ¼ picosecond (ps). Our approach to this problem was three pronged. First, it was our intent to build a streak camera with ½ ps resolution. This conventional diagnostic was to be used to verify the results of two novel measurement techniques. Second, we wished to investigate the utility of off-axis coherent Smith-Purcell radiation as a bunch-length diagnostic. Finally, we planned to demonstrate a measurement of the electron bunch-length using a transversely deflecting RF field and a beam position monitor (BPM). Background and Research ObjectivesThe generation of very short bunch lengths (temporal duration of 1 ps or less) is a
