Cyclotron-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 کاملPhonon Effects on the Cyclotron Resonance for a Many-body System: a Generalized Quantum Langevin Equation Approach
We have recently developed a new approach to the derivation of quantum transport results for an interacting many-body system of electrons, impurities and phonons. Now, using a similar philosophy, the cyclotron resonance lineshape (CRLS) of an electron-phonon many-body system is studied by the generalized quantum Langevin equation approach, in which the memory function is obtained directly by so...
متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
Cyclotron Resonance in High Magnetic Fields
We review recent cyclotron resonance studies of semiconductors performed in high magnetic fields. This traditional semiconductor characterization method has been used to study some of the recentlydeveloped materials systems, including ferromagnetic III-V semiconductors and two-dimensional electron gases formed in InSb/InAlSb and GaN/AlGaN heterostructures. These studies have not only provided a...
