Drift velocity in non-isothermal inhomogeneous systems

Drift wave vortices in inhomogeneous plasmas

The effects of density and temperature gradients on drift wave vortex dynamics are studied using a fully nonlinear model with the Boltzmann density distribution. The equation based on the full Boltzmann relation, in the short wavelength ( -ps ) region, possesses no localized monopole solution, while in the longer wavelength [ (psrn ) “‘1 region the density profile governs the existence of monop...

Isothermal and Non-isothermal Methods

a comparison was made between the experimental non-isothermal a vs. t curves and those calculated on the basis of a previous isothermal study. It was observed that for low heating rates, when the "thermal lag" is negligible, the dynamic measurements are in good agreement with the isothermal ones. Furthermore, for process (I), two mathematical methods proposed for the interpretation of the non-i...

Electron Drift Velocity in the μBooNE TPC

As the readout time associated with a trigger of μBooNE is proportional to the drift time, it is important to know the drift velocity precisely. Likewise, the reconstruction of track position from the drift time of ionization electrons depends on knowledge of the drift velocity. The nominal drift field in μBooNE is E = 500V/cm, and the peak electric field at the surface of the collection wires ...

Electron ’ drift velocity and diffusivity in germanium

Experimental results for electron drift velocity and diffusivity in germanium, obtained with the time-of-flight technique in hyperpure material. are presented for temperatures between 8 and 240 K and fields between 1 and 104,V/cm oriented along (111) and (100) directions. An anisotropy of the drift velocity and of the diffusion coefficient is found with the electric field applied along (111) an...
