Maser Theory
This review covers some of the developments in basic theory of astronomical masers over the past ten years. Topics included are the effects of three dimensional geometry and polarization, with special emphasis on the differences between maser and non-maser radiation. 1. Maser Absorption Coefficient in Three Dimensions The absorption coefficient κ describes the coupling between particles and rad...
متن کاملCompton scattering as a probe for materials investigation
This article investigates into the feasibility of using gamma radiation Compton backscatter spectra as a means of material characterization, with the view to developing a portable, hand held probe for investigative purposes such as searching for illicit substances hidden in wall or car door cavities.
متن کاملPolarized maser growth.
A polarized maser is assumed to operate in an anisotropic medium with natural modes polarized differently to the maser. It is shown that when the spatial growth rate and the generalized Faraday rotation rate are comparable, the polarization of the growing radiation is different from those of the maser and medium. In particular, for a lineary polarized maser operating in a medium with linearly p...
متن کاملCyclotron-resonance maser in a magnetic mirror.
A cyclotron-resonance maser (CRM) experiment is performed in a high-gradient magnetic field using a low-energy electron beam ( approximately 10 keV/1 A). The magnetic field exceeds 1.63 T, which corresponds to a 45-GHz cyclotron frequency. The CRM radiation output is observed in much lower frequencies, between 6.6 and 20 GHz only. This discrepancy is explained by the finite penetration depth of...
متن کاملA 32-Gigahertz Coupled-Cavity Maser Design
A 32-GHz coupled-cavity maser design is described. The theory and the predicted performance of cavity masers are included. A coupling cavity in the signal waveguide enables tuning of the maser over the 500-MHz-wide deep-space frequency allocation from 31.8 GHz to 32.3 GHz. The ruby cavity is simultaneously resonant at 32 GHz in the TE101 mode and at the pump frequency of 66.4 GHz in the TE301 m...
