SIMBUCA (before called Simonion) is a simulation package that simulates the motion of charged particles under the influence of Electric and/or Magnetic fields.
What makes Simbuca unique is that you can choose to calculate the Coulomb interaction between ions on a Graphics cards which is much faster than calculating this on the conventional CPU (reducing the simulation time from years to days).

Therefore Simbuca has been applied in various projects which required to understand the behaviour of charged "trapped" particles under the influence of EM Fields and there mutual Coulomb interaction.

Simbuca is easy to read and understand and can be tweaked to your personal needs.
It has been applied to simulate different types of particles: for example antiprotons, positrons, 39K+ , highly charged ions, negatively charged particles.

Simbuca also has been applied to simulate Penning/Paul traps, Mr-TOFs, RFQs, ...

Features

  • Abililty to import external magnet fieldmaps + electrical fieldmaps (f.e. with SIMION,Comsol, Matlab)
  • Ability to do trapexcitations: dipole, quadruple, octupole + rotating wall (dipole,quadrupole)
  • MPI enabled: Simbuca can run on miltiple CPUs
  • 3 Realistic (hard sphere) buffer gas models
  • Can run on more than 1 GPU
  • Different ODE's implemented (4,5th order), all with adaptive stepsize (and error control). Also a predictor algorithm is implemented
  • Major improvement by using the option to run on a GPU for the Coulomb interaction calculation
  • ROOT analysis files + bash analysis files
  • increased flexibility: an inputfile can be used with all the required simulation parameters

Project Samples

Simbuca is also used in othe applications were the Coulomb interaction and EM field tracking is required like e.g. an MR-TOF: Simulated ToF spectra of an initial mixture of CO + (red) and N 2 + (blue) ions (ToF compared to the non-interacting N 2 + reference ion). The trapping time increases from top to bottom of every part of the picture (details in picture). The Coulomb scaling factors are a: 0 (no Coulomb interaction), b: 5, c: 10, d: 20. Picture taken from M.Rosenbush: AIP Conf. Proc. 1521 , 53 (2013); doi: 10.1063/1.4796061 Test of Simbuca by comparing it with the equations of motion of a dipolar excitation at the eigenfrequency n. Perfect correspondence between simulation and theory is found Movement of the ion cloud in the X,Y-plane of the trap (in mm). The left column represents 1000 ions without Coulomb interaction. Coulomb interactions between ions are taken into account in the right column. Here 1000 ions are each given a charge of 10^4+ to represent 10^7 ions. Ions move 50 μs between the frames. Due to the Coulomb interaction in the cloud, the ion rotates around the center of the cloud (right column). Without Coulomb interaction taken into account the ion stays at the same position inside the cloud (left column).
