The Field Cathodes with the Effect of Space Charge Modeling
نویسندگان
چکیده
This work is devoted to the question of the effect of space charge on the field electron emission. The electrostatic potential distributions for the diode emission systems are calculated. The diode systems, which can be readily constructed, are generally used for the characterization of field emission properties of novel materials. They have some effective applications in vacuum nanoand microelectronics. In this work the plane diode emission system and cylindrical diode emission system are investigated. The solutions of Poisson’s equation for the electrostatic potential distribution are received for the boundary-value problems. The right side of Poisson’s equation is assumed to be the piecewise constant function. The charge conservation law and the energy conservation law are used. One and two dimensional cases are investigated.

Field Emission Cathodes used in the FEGI Get-Away-Special Shuttle Mission
Field emission cathodes are presently being developed as low-power space electric propulsion neutralizers and for spacecraft charge control and electrodynamic tether applications requiring no consumables. These cathodes effect cold electron emission by the application of a relatively high electric field across a small gap from some kind of electron emitting (cathode) surface. Various designs of...

This research is based on the modeling of co-seismic deformations due to the fault movement in the elastic environments, and we can obtain the deformations generated in the faults. Here, modeling of the co-seismic displacement field is based on the analytical method with two spherical dislocation model and half-space dislocation model. The difference in displacement field from two spherical and...

By studying the properties of matter during heavy-ion collisions, a better understanding of the Quark-Gluon plasma is possible. One of the main areas of this study is the calculation of the magnetic field, particularly how the values of conductivity affects this field and how the field strength changes with proper time. In matching the theoretical calculations with results obtained in lab, two diffe...

متن کاملAn Algorithm for Modeling and Interpretation of Seismoelectric Data
Generally speaking, seismoelectric modeling is a prospecting method based on seismic and electromagnetic waves, in which waves generated by a seismic source at the boundary of the two environments generate a relative fluid-solid motion formed as a result of antagonism between the elastic properties of the environment with the saturated fluid. This research has as its objective, a study of the e...
