Simulation of ion beam irradiation

Zgoubi is a raytracing code. Since 1972 it pushes charged particles through accelerators and beam lines, by stepwise solution of Lorentz force equation - and their spins via Thomas-BMT differential equation. Zgoubi simulates beam dynamics and polarization in a variety of accelerators (storage ring, synchrotron, cyclotron, betatron, microtron, FFAG, multi-pass ERL, etc) and optical systems (beam lines, magnetic and electrostatic optical components, time-of-flight and mass spectrometers, etc). ...

PyZgoubi is an interface to the Zgoubi particle tracking code written in python. It aims to ease the use of Zgoubi by providing a simple interface to create beam line elements and particles, and to automate running and analysing of simulations.

The DREAM (Discrete REpresentation Array Modelling) toolbox is a free open source toolbox, for both Matlab and Octave , for simulating acoustic fields radiated from common ultrasonic transducer types and arbitrarily complicated ultrasonic transducers arrays. The DREAM toolbox enables analysis of beam-steering, beam-focusing, and apodization for wideband (pulse) excitation both in near and far fields. The code in the svn repository # svn co http://svn.code.sf.net/p/dreamtoolbox/code/trunk dream is not used actively anymore and is kept here for referecne only. The development code has moved to git on: https://github.com/frli8848/DREAM

EVERTims is a real-time room acoustic simulation software based on EVERT beam-tracing library providing information of specular reflection paths of sound in a space.

EVERT is an acoustic beam-tracing library. It is optimized for a moving listener with static geometry and sound source. It computes all the visible specular reflection paths up to the given reflection order.

LaserCalc is an Open Source wxWidgets application for the calculation of optical beam paths and laser resonators based on Gaussian beam matrix optics. In addition beam paths can be optimized to match given beam parameters (mode matching).

A multiparticle tracking postprocessor library for accelerator physicsists.

Modal Interferometer Simulation Tool (MIST) is a MATLAB toolbox that can simulate arbitrary resonant optical systems in the paraxial beam approximation. It allows the user to define any optical setup (composed typically of laser sources, mirrors, lenses, electro-optical modulators and detectors) and to compute the static laser field at any point. It uses a Hermite-Gauss modal decomposition to simulate diffraction limited optics. This tool is being developed mainly for simulation of large scale interferometers with resonant cavities used for the detection of gravitational waves. ...

...A numerical model is programme to calculate, for realistic experimental configurations, effective Raman line strength functions, which find their way into depolarization ratios. The model is based on interlinked integrations over the angles in the light collection path, and a finite Raman source volume along the excitation laser beam. The model deals as well with the conditional aperture parameters, associated with more than one optical component in the light collection path. Finally, the model also takes into account polarization aberrations introduced by the sample cell windows.

...It's possible to save simulations and to restart calculations from this safepoints. A tempSave-file is written to restart simulations, if they crash from an earlier point. Now in v2 an example is added with a FEM beam and a moving piston. Both are hardcoded in the code and must be changed if you want to use it otherwise. Now it can be used only 1 bar and 1 piston, for future it will be changed. Video of textcase: http://www.youtube.com/watch?v=TLYVSWkhXBI Software is tested and runs stable with up two 5000 SPH particles. Known Problems: If there are more than 15000-20000 SPH particles, after some simulationssteps the calculation slows down and gains all memory. ...

SpectrumGUI can generate filtered spectra for various x-ray tubes and can display attenuation coefficients for various materials. It also computes exposure and beam quality for various tube settings.

Lunessaphir Mini Beam Simulator is a simulator of antenna propagation.You can see easily the spacial radiation patterns of array antenna like a thermogram, depending on amplification and phase of each antenna element.

Set of scripts based on gaussian optics, which allow you to analyze the image waist created from a gaussian beam, and quickly determine 1-lens and 2-lens mode matching configurations to match a beam waist to another waist size

In the selective laser melting process (SLM), components are built up layer by layer by incremental melting of metal powder with a laser beam. This process leads to locally inhomogeneous material properties of the manufactured components. By integrating these specific material properties of the SLM-process into a topology optimization, product developers can be supported in the design process by simulation. For this purpose, a topology optimization method is being developed which takes into account the unique material properties of parts manufactured with the SLM-process. ...
