O(h̄) effects that modify the classical orbit of a charged particle are described for the case of a classical spin2 particle moving in a constant magnetic field, using a manifestly covariant formalism reported previously. It is found that the coupling between the momentum and spin gives rise to a shift in the cyclotron frequency, which is explicitly calculated. In addition the orbit is found to ...

Microwave-radiation induced giant magnetoresistance oscillations recently discovered in high-mobility two-dimensional electron systems are analyzed theoretically. Multiphoton-assisted impurity scatterings are shown to be the primary origin of the oscillation. Based on a theory which considers the interaction of electrons with electromagnetic fields and the effect of the cyclotron resonance in F...

A bolometric diagnostic system with features necessary for steady-state operation in the superconducting stellarator W7-X was designed. During a pulse length of 1800 s with an ECRH (electron cyclotron resonance heating) power of 10 MW, the components suffer not only from a large thermal load but also from stray radiation of the nonabsorbed isotropic microwaves. This paper gives an overview of t...

We use the cyclotron-maser theory to explain the core emission from the magnetosphere of pulsars. As a kind of direct and efficient maser type of emission, it can give rise to escaping radiation with extremely high brightness temperature and narrow angle with respect to the magnetic axis. We find that the growth rates and real frequencies of the O-mode electromagnetic wave propagating parallel ...

Introduction: Energetic particles and plasma dynamics in the near-Earth space environment can significantly impact operation of both military and civilian systems. The underlying physical mechanisms relevant to two important space plasma issues, radiation belt dynamics and auroral ionospheric space weather, are under investigation in the NRL Space Physics Simulation Chamber (SPSC). Plasma condi...

Excitation of 10-GHz gigawatt-range radiation pulses ~ 1 ns long in relativistic backward-wave oscillators with an elongated periodic slow-wave system has been studied. Accelerators based on a compact pulsed-periodic high-voltage generator type SINUS-160 and a generator employing an inductive energy storage, a semiconductor opening switch and a peaking hydrogen-filled spark gap have been develo...

We show the first evidence for locally excited chorus at frequencies below 0.1 fce (electron cyclotron frequency) in the outer radiation belt. A statistical study of chorus during geomagnetic storms observed by the Van Allen Probes found that frequencies are often dramatically lower than expected. The frequency at peak power suddenly stops tracking the equatorial 0.5 fce and f/fce decreases rap...

Detection of THz radiation by a Field Effect Transistor InGaAs/InAlAs transistor was investigated at 4.2 K as a function of the magnetic field and gate voltage. We observed oscillations of the photovoltaic signal analogous to Shubnikov-de Haas oscillations, as well as their strong enhancement at the cyclotron resonance conditions. The results are successfully quantitatively described within the...
