TL;DR: In this paper, it was pointed out that electron storage rings, in addition to their intended purpose and their secondary use as intense sources of x rays, might also serve as pulsar simulators, producing a similar spectrum of coherent emission, the properties and modification of which could be studied in the laboratory.
Abstract: Energetic electron bunches in storage rings produce pulsed bursts of incoherent synchrotron radiation. It is pointed out that they should also produce a roughly comparable power output of coherent radio-frequency radiation. Thus electron storage rings, in addition to their intended purpose and their secondary use as intense sources of x rays, might additionally serve as pulsar simulators, producing a similar spectrum of coherent emission, the properties and modification of which could be studied in the laboratory. A spontaneous bunching of electrons (artificially bunched here) might be evidenced as ''superbunching.''

15 Nov 1982TL;DR: In this paper, an annular beam of gyrating electrons is produced which is then compressed to its paraxial position by means of a solenoid magnetic field around the wave-guide.
Abstract: A source of coherent electromagnetic radiation capable of generating or amplifying waves in the centimeter, millimeter, and submillimeter wavelength range. An annular beam of gyrating electrons is produced which is then compressed to its paraxial position by means of a solenoid magnetic field around the wave-guide. This electron beam is also subjected to a transverse motion in an interaction region by a longitudinal rippled (wiggler) magnetic field. Such a field is generated by a periodic assembly of rings magnetized in the axial direction. The electron beam during its accelerated motion generates or amplifies coherent electromagnetic radiation in the centimeter, millimeter, or submillimeter range.

TL;DR: Guided submillimeter radiation (λ =118.8 μm) has been focussed by inserting a cylinder lens into the freely propagating beam in front of the incoupling prism as discussed by the authors.
Abstract: Guided submillimeter radiation (λ=118.8 μm) has been focussed by inserting a cylinder lens into the freely propagating beam in front of the incoupling prism. The beam profile at the focal spot has been determined experimentally, the results agree with theoretical predictions. The optical quality of the focus is good.
