CONSULTING SERVICES

eGUN/iGUN DESIGNS
Tools: PBGUNS, IonEx, and SolidWorks
We can help with the design of your electron and ion guns using FAR-TECH's simulation codes (PBGUNS and IonEx) along with the commercial CAD software package SolidWorks. To request further information or a quote, please click here.

HFSS Simulation
Tools: HFSS, SolidWorks, and in-house particle codes
We can create custom-order designs for your accelerator structures and RF components, with RF tests using HFSS and in-house particle codes. To request further information or a quote, please click here.

FAR-TECH has expertise with a wide variety of third-party codes, including HFSS, MAGIC, G4Beamline, PARMELA, and ELEGANT. Parallel-capable codes are run on a parallel cluster with Infiniband interconnect. SolidWorks is used for mechanical CAD, thermal, and stress-strain evaluation. We also develop internal codes for simulating electromagnetic and plasma phenomena, including codes based on the innovative particle-in-cloud-of-points method.

The figures below show, from left to right: a portion of a multi-beam klystron using SolidWorks; the field pattern near the RF coupler, which was obtained by HFSS; and FAR-TECH’s novel accelerator structure. These projects are supported by the U.S. Department of Energy.

COMSOL Modeling
FAR-TECH has been using COMSOL to solve physical problems for many years. We can now help you solve your problems using COMSOL. We have a server license and thus can solve memory-intensive problems. To request further information or a quote, please click here.

Fluid Simulations by COMSOL
COMSOL was used to model the merging of three water jets, one of which has less ram force than the others. Two different cases are shown below.

Plasma Simulations Using COMSOL
Utilizing COMSOL, we developed the code FARVAC, which evaluates magnetic fields between the plasma and the wall in a toroidal device. The figure on the left shows the magnetic field lines and the color-contoured magnetic fields for a conducting wall; on the right is the magnetic fields for a resistive wall.

The figures below show the magnetic field lines and the color-contoured magnetic fields for the first three eigen wall modes.

LSP Simulation
We have been using the LSP code for a number of years to simulate plasma jet merging, klystrons, and electron gun designs. We can provide simulations with LSP to solve your problems. To request further information or a quote, please click here.

The figures below show, from left to right: two high-density, high-Mach-number plasma jets merging; a wasp-shaped plasma jet accelerator geometry; and an instability (the so-called “blow-by” instability) of the plasma jet in the accelerator.

Another interesting LSP simulation result is shown below. It shows a blob of plasma penetrating from left to right across vacuum magnetic fields. There is no magnetic field to the left of 3 in the horizontal axis. Ion density, velocity and the fields are plotted in sequence. This case shows that the plasma jet blob penetrated, intact, across the fields.
