Kinetic stability properties of nonrelativistic non-neutral electron flow in a planar diode with applied magnetic field

Pfc/ja-84-36 Influence of Profile Shape on the Extraordinary-mode Stability Properties of Relativistic Nonneutral Electron Flow in a Planar Diode with Applied Magnetic Field

The cold.-fluid extraordinary-mode eigenvalue equation is solved numerically to determine the influence of equilibrium profile shape on the detailed stability properties of relativistic nonneutral electron flow in a planar diode with cathode located at x=O and anode at x=d. Stability properties are investigated for the class of equilibrium energy profiles Yb(x) specified by [1-a (b2_ 2 1/2 Yb(x...

Properties of non-neutral electron plasmas confined with a magnetic mirror field.

A low energy non-neutral electron plasma was confined with a magnetic mirror field and an electrostatic potential to investigate the basic confinement properties of a simple magnetic mirror trap. The mirror ratio of the magnetic field was increased up to 5. As expected the confinement time became longer as a function of the mirror ratio. The axially integrated radial density profiles in equilib...

Electron Beam Dose Distribution in the Presence of Non-Uniform Magnetic Field

Introduction Magnetic fields are capable of altering the trajectory of electron beams andcan be used in radiation therapy.Theaim of this study was to produce regions with dose enhancement and reduction in the medium. Materials and Methods The NdFeB permanent magnets were arranged on the electron applicator in several configurations. Then, after the passage of the electron beams (9 and 15 MeV Va...

Effect of static magnetic field on the hemodynamic properties of blood flow containing magnetic substances

The use of magnetic fields in targeted drug delivery, especially for treatment of cancers and tumoral regions, is one of the significant techniques in the field of modern methods of treatment. Considering that many vital biological tissues have been located deep in the body, then for targeted drug delivery and effective treatment in these tissues, it is required to bring therapeutic agent to th...
