Many improvements to our programs follow from user suggestions. My consulting projects often provide motivations for new features. I am presently working on a simulation of a large cylindrical vacuum insulator for a pulsed-electron-beam injector. The issue is whether non-symmetrical flaws in the insulator surface will cause substantial field perturbations. I started by creating a 2D [...]

In the Track mode (single-particle orbits), OmniTrak has long had the capability of including temporal modulations of electric and magnetic fields to approximate RF fields in the long-wavelength limit. For electric fields, the procedure has been to multiply potential values by a modulation function M(t). Recently, I have worked on an application to design an RF [...] In EStat and HiPhi, the term floating electrode refers to a fixed-potential region where φ is determined by capacitive or resistive division. In other words, the potential depends on the electrostatic solution and is not known in advance. For regions with non-zero volume, the standard method is to assign a high value of conductivity or relative dielectric [...] To check for breakdown conditions in high-voltage systems, it is useful to know the distribution of electric-field over surfaces of electrodes and dielectrics. Recently, a customer who has used the software for 10 years asked me if EStat had this capability. It took me several minutes of searching to answer the question. My conclusion is that [...] |
