2D Solver
Axisymmetric structures with azimuthal harmonics, and planar structures of fixed width. Stationary or moving window. OpenMP threads.
Wakefield simulation for particle accelerators
EMUZAG computes wake potentials, impedances and material losses of accelerator components in the time domain: a 2D Solver, a 3D Solver, and Studio, the application both are run from.

Release 1.1.2 of 27 October 2026
EMUZAG simulation model highlights
Dispersive and layered materials. A ferrite kicker with every kind of material in one model: a yoke of five ferrite segments with a Lorentz pole in μ, a one-turn copper conductor, steel ends, and an alumina chamber whose 1 µm titanium coating is a layer model and is not meshed. Half of it is drawn, cut at the symmetry plane. A demonstration model, not an existing magnet and not a computed result.
Imported geometry. The TESLA nine-cell cavity with its couplers, imported as the vacuum volume and solved in 3D with a window that moves with the bunch. Its computed field is played further down this page; the run is on the Examples page.
Tapers and small gaps. A rectangular collimator whose gap narrows from 38 mm to 1.4 mm and opens again; the Quick Start guide begins with this model. Its computed field is played further down this page.
Dielectrics. A dielectric wakefield structure: a fused-silica liner in a copper jacket, with conical transitions to steel beam pipes. Half of it is drawn, cut at the symmetry plane. A demonstration model; its computed field is played further down this page.
The field a bunch leaves behind, computed by the 2D and 3D Solvers and played from their recorded output
TESLA nine-cell cavity. The longitudinal field of a bunch on the axis, on the plane through the beam axis: red positive, blue negative. The cells keep ringing after the bunch has left. The section is drawn at its true proportions.
Tapered collimator. The same quantity for a short bunch passing the 1.4 mm gap.
Dielectric-lined tube. Behind the bunch the fused-silica liner rings in its own modes. A demonstration model.
Corrugated pipe, 2D Solver. An axisymmetric run: the half above the axis is computed and mirrored for the picture. The wake keeps ringing in the grooves after the bunch has passed. A demonstration model.
EMUZAG Studio: geometry, materials, mesh, jobs and results in one window
Studio needs no licence. It runs on Windows x64 and on macOS on Apple Silicon, and on the graphical nodes of Linux clusters, from where 3D jobs go to Slurm.
3D Solver
General geometry from CAD (STEP, BREP) or STL on a conformal Cartesian mesh. Moving window at β = 1; stationary runs also for β < 1. MPI processes and OpenMP threads.
