The slow-wave cyclotron-resonance master ~CRM! oscillator experiment presented in this paper produces output signals that correspond to normal and anomalous Doppler shifts. The table-top low-voltage (,10 kV! CRM device consists of a double stripline waveguide. The metal strips are loaded by dielectric slabs; thus the waveguide supports slow waves with different phase velocities in odd and even ...

[1] We calculate growth rates for extraordinary mode Saturnian kilometric radiation generated by the electron cyclotron maser instability using a ring‐type (DGH) electron phase distribution model fitted to measured electron energy dist r ibut ions in Saturn’s auroral acceleration region. The observed distributions are unstable in spatially isolated regions of transverse linear size of order 10 ...

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...

Collective Thomson scattering (CTS) is expected to provide the spatially resolved velocity distribution functions of not only thermal and tail ions but also alpha particles resulting from fusion reactions. CTS using gyrotrons with frequency higher than the conventional ones used for plasma heating would have advantages to alleviate refraction, cutoff effects, and background electron cyclotron e...

the radioisotope 67ga (t 1/2 = 78 h) in extensively used as single photon marker for detecting the presence of malignancy and the diagnosis of inflammatory diseases. the high tumor specificity of carrier-free 67ga make it one of the most interesting radionuclides in nuclear medicine for in vivo scanning studies.67ga is a cyclotron produced radioisotopes and is one of the radiopharmaceuticals wh...

In earlier papers (Kellogg and Lin 1997, Kellogg 2000, Kellogg et al 2001) which attempted to understand what effects were responsible for the violation of the conservation of magnetic moment in the solar wind it was pointed out that electric fields in the range which would resonate with the ion cyclotron frequency have not been adequately investigated. In most spinning spacecraft, fields in th...

The Barut–Zanghi (BZ) theory can be regarded as the most satisfactory picture of a classical spinning electron and constitutes a natural “classical limit” of the Dirac equation. The BZ model has been analytically studied in some previous papers of ours in the case of free particles. By contrast, in this letter we consider the case of external fields, and a previously found equation of the motio...

Two-dimensional solutions of compressional Alfven eigenmodes (CAE) are studied in the cold plasma approximation. For finite inverse aspect ratio tokamak plasmas the two-dimensional eigenmode envelope is localized at the low magnetic field side with the radial and poloidal localization on the order of u / f i and u/*, respectively, where rn is the dominant poloidal mode number. Charged fusion pr...
