Title: Radiation properties of cavity Cerenkov radiation

Abstract

Cerenkov radiation from cavities has been analyzed by quantum electrodynamic theory. Analytical expressions of basic radiation properties such as the Einstein's A and B coefficients are derived and shown to be directly modified by the cavities. The analysis leads to the conclusion that the coherent radiation from the Cerenkov radiation devices is due to super radiance of spontaneous emission instead of stimulated emission. Coherent and incoherent radiations are analyzed in the THz radiation range.

  • The properties of Cerenkov radiation are analyzed for a small radiator thickness. It is shown that the directionality of the radiation, its threshold properties, and also the dependence on the electron energy and radiator thickness differ substantially from the well known characteristics of Cerenkov radiation corresponding to the case of an unlimited particle trajectory in an extended medium. We have experimentally studied the directionality and energy characteristics of radiation excited by electrons in a mica target of thickness 12 400 A at wavelength 4000 A. The experimental results are in good agreement with the calculations.
  • In this account of Cherenkov radiation, the optical analogue of the supersonic bang,'' great emphasis is laid on the underlying physical principles of the effect. The historical introduction is followed by a qualitative account of the basic mechanism of the generation of light by the passage of fast charged particles through homogeneous transparent media. After a discussion of the relationship of Cherenkov radiation to other processes connected with the interaction of fast particles with matter, the practical applications of Cherenkov detectors and counters in the fields of cosmic ray and high-energy physics are discussed. In conclusion, some interesting experiments carriedmore » out on light flashes from the night sky are described.« less
  • This paper presents preliminary research on a V-band overmoded Cerenkov generator with dual-cavity reflector operating in a low guiding magnetic field. It is found that the fluctuation of the electron envelope in the low guiding magnetic field can be predicted using an equivalent coaxial model of a foilless diode, and a dual-cavity reflector based on the model matching method can provide strong reflection at the front end of the overmoded structures so that any microwave power that leaks into the diode region can be effectively suppressed. Numerical simulations indicate that the control of the beam envelope and the use ofmore » the dual-cavity reflector ease generator operation in the low guiding magnetic field. In the experimental research, the fluctuation of the annular electron beam with the outer radius of 7.5 mm measures approximately 0.7 mm, which is in good agreement with the theoretical results. The disturbance caused by power leaking from the overmoded slow wave structure is eliminated by the dual-cavity reflector. With accurate fabrication and assembly processes, an operating frequency of 61.6 GHz is attained by the fifth harmonic heterodyne method, and the output power is measured to be approximately 123 MW by the far-field measurement method at a diode voltage of 445 kV, a beam current of 4.45 kA, and under a guiding magnetic field of 1.45 T. The output mode is measured using an array of neon flash bulbs, and the pulse shortening phenomenon is both observed and analyzed.« less
  • The problems involved in increasing the efficiency of cavity solar-energy collectors are considered when radiation-absorption surfaces with selective characteristics are employed. It is shown that in cavity-type solar collectors with selective radiation-absorption characteristics there is an optimum cavity depth determined by the heating temperature and radiation characteristics that will insure maximum efficiency of the radiation receiving surfaces of solar-radiation collectors.
