Several effects in coherent transition radiation which may be understood analytically and which influence the character of the x‐ray spectrum resulting from a stack of foils are discussed. In particular, coherence effects may produce a radiation pa

In a recent Letter, Ohkuma, Okuda, and Tsumori [1] (OOT) report the observation of coherent Cherenkov radiation produced by a single bunch of 30-MeV electrons. Electrons passing through a Ti foil window traveled a path of 50 cm through air before str

Most developments of Cerenkov Radiation are in terms of the Fourier components of the fields and power emitted by a single electron. When many electrons in a compact bunch are emitted from an accelerator, the bunch radiates coherently and at a lower

The electron beam in a free electron laser (FEL) becomes axially modulated at the optical wavelength of the FEL radiation. This electron beam passed through a gas may produce intense Cherenkov radiation. The effects of the radial and axial dimension

Cerenkov radiation is calculated for electron beams which exceed the velocity of radiation in a nondispersive dielectric medium. The electron beam is assumed to be bunched as emitted from a traveling-wave accelerator, and the emission region is assum

Measurement of microwave Čerenkov radiation is air show that the Čerenkov cone angle is broadened as predicted in earlier work. Extension of previous theory shows that for small Čerenkov angles, the broadening is asymmetric, giving an increase in

Plane elastic waves traveling in an arbitrary direction in a crystal are, in general, neither transverse nor longitudinal and in fact show polarization angles up to 11° in nickel. A method for deducing the elastic constants of a cubic crystal is wel

Polycrystalline alloys of iron in vanadium up to 15.32 at. % were prepared principally by arc melting. Longitudinal and shear ultrasonic measurements in the 10–30 MHz range were made at room temperature. The resulting longitudinal modulus increased
