Homogeneous pressure decay in multi-chamber vacuum system with finite conductance
Fernando F. Dall'Agnol, Felipe Vieira, Francisco T. Degasperi
We derived the geometrical parameters on the tube connections that homogenize the pressure drop in a multi-chamber vacuum system, where each chamber has a distinct volume and all a…
Field emitter electrostatics: efficient improved simulation technique for highly precise calculation of field enhancement factors
Fernando F. Dall'Agnol, Thiago A. de Assis, Richard G. Forbes
When solving the Laplace equation numerically via computer simulation, in order to determine the field values at the surface of a shape model that represents a field emitter, it is…
Field emitter electrostatics: a review with special emphasis on modern high-precision finite-element modelling
Thiago A. de Assis, Fernando F. Dall'Agnol, Richard G. Forbes
This review of quantitative field emitter electrostatics, covering analytical, numerical and fitted-formula approaches, is thought the first of its kind. The review relates chiefly…
Driving upside-down in a circular track
Fernando F. Dall'Agnol, Lucas B. de Morais, Marcelo D. Alloy
In this article, we point out an interesting solution for the dynamics of a racecar in a banked circular track with banking angle well over 90o. We call this track configuration an…
Minimal domain size necessary to simulate the field enhancement factor numerically with specified precision
Thiago A. de Assis, Fernando F. Dall'Agnol
In the literature about field emission, finite elements and finite differences techniques are being increasingly employed to understand the local field enhancement factor (FEF) via…
Physics-based derivation of a formula for the mutual depolarization of two post-like field emitters
Fernando F. Dall'Agnol, Thiago A. de Assis, Richard G. Forbes
Recent analyses of the field enhancement factor (FEF) from multiple emitters have revealed that the depolarization effect is more persistent with respect to the separation between…
