Simulation of the Space Charge Effect in RHIC
Space charge forces, representing the weak-strong case, are simulated by kicks from a line charge having a 2D-Gaussian transverse charge distribution. A series of particles having initial coordinates consistent with the dimensions of the injected beam are tracked sequentially, and tunes are obtained from analysis of the coordinates, x, x, y, and y, at the end of each turn. Stability is tested u...
متن کاملThe Field Cathodes with the Effect of Space Charge Modeling
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 microel...

15 صفحه اولIngredients for the Understanding and the Simulation of Multipacting
The resonant multiplication of electrons in accelerator is known to degrade the performance of devices where appropriate conditions are fulfilled between, the oscillating electrical field, the dimensions of the vessel and the ability of the surface to multiply electrons. This latter property is described by the secondary electron yield (S.E.Y.). Although the S.E.Y. of most pure materials are kn...
متن کاملModeling low pressure collisional plasma sheath with space-charge effect
The present work develops a computationally efficient one-dimensional subgrid embedded finite element formulation for plasma-sheath dynamics. The model incorporates space-charge effect throughout the whole plasma and the sheath region using multifluid equations. Secondary electron emission is not considered. A third-order temperature dependent polynomial is used to self-consistently calculate t...
