We have observed x-ray emission from transition radiators placed inside an electron storage ring. The radiators were thin (0.18–9 μm) and the electrons were of sufficient energy (118–252 MeV) so that the electrons passed through the radiators ma

Quartz and nickel cylinders were used as grazing incidence x‐ray optics for transition radiation (TR) from Al, Ti, and Cu foil stacks. The cylinders were used to direct the otherwise diverging TR to a small spot (1 mm diameter), with measured fluxe

This article describes the measurements of x‐ray power, spatial and spectral distributions from transition radiators whose spectra are narrowed by the foil material’s K‐shell photoabsorption edge. We used two foil stacks, one composed of 15 foi

By designing transition radiators to emit x-rays at the foil material's K-, L-, or M-shell photoabsorption edge, the x-ray spectrum is narrowed. The source is quasimonochromatic, directional, and intense and uses an electron beam whose energy is cons

We have measured the profile of x rays generated by a transition radiator and focused by simple cylindrical optics. Soft x rays with photon energies between 1 and 4 keV were generated by a 93‐MeV electron beam striking a stack of eight foils of 3.5

We have measured the total soft‐x‐ray power from a transition radiator composed of a stack of 25 beryllium foils each 1.0 μm thick which were penetrated by a relativistic electron beam whose maximum power was approximately 7 kW. The maximum tota

Soft x rays were produced by a stack of 12 aluminum foils, each 1.0 μm thick, which were bombarded by a relativistic electron beam whose maximum power was ∼10 kW. The maximum total soft x‐ray flux was measured to be 8 mW, a factor of 10 over the

Transition and Parametric radiators are proposed as sources for EUVL and XRL. Collimated soft x rays and extreme ultraviolet (EUV) radiation can be generated using electron beams with moderate electron-beam energies, unlike synchrotron radiators, whi

We present quantifiable images of the angular distributions (AD`s) of parametric x radiation (PXR), and vacuum-ultraviolet transition radiation (vuv TR) from 230 MeV electrons interacting with a silicon crystal. Both AD`s are highly polarized. The vu
