Particle Designer 2 7

Currently most of the platforms that Particle Designer exports for don't support a single system with multiple emitters. For this reason you can export a stage file from PD which allows you to read in details of where multiple emitters should be placed to work together. Admittedly this is a file that would need to be read manually and then used.
Where Particle Designer 1 and 2 were aimed to accompany Game Maker, a new version would focus on the generation of the effect as a graphic for any platform. For this to work properly, seemless transitions of the animations would be useful to make professional looking effects without the use of actual particles for certain situations.

(Redirected from Methodical Accelerator Design)

A charged particle accelerator is a complex machine that takes elementary charged particles and accelerates them to very high energies. Accelerator physics is a field of physics encompassing all the aspects required to design and operate the equipment and to understand the resulting dynamics of the charged particles. There are software packages associated with each such domain. There are a large number of such codes. The 1990 edition of the Los Alamos Accelerator Code Group's compendium ^[1] provides summaries of more than 200 codes. Certain of those codes are still in use today although many are obsolete. Another index of existing and historical accelerator simulation codes is located at ^[2]

Thus, Particle Designer 2 was started in November 2006. With all of the additions, many more scripts and graphics were needed, so it took a long time to complete. Version 2.0 was released on April 12th, 2007.

Columns[edit]

Spin Tracking: Tracking of a particle's spin.

Taylor Maps: Construction of Taylor series maps that can be used for simulating particle motion and also can be used for such things as extracting single particle resonance strengths.

Collective effects: The interactions between the particles in the beam can have important effects on the behavior, control and dynamics. Collective effects take different forms from Intrabeam Scattering (IBS) which is a direct particle-particle interaction to wakefields which are mediated by the vacuum chamber wall of the machine the particles are traveling in. In general, the effect of direct particle-particle interactions is less with higher energy particle beams. At very low energies, space charge has a large effect on a particle beam and thus becomes hard to calculate. The above simulation codes do not handle low energy space charge effects. See below for a list of programs that can handle low energy space charge forces.

Synchrotron radiation tracking: Ability to track the synchrotron radiation (mainly X-rays) produced by the acceleration of charged particles.

Wakefields: The electro-magnetic interaction between the beam and the vacuum chamber wall enclosing the beam are known as wakefields. Wakefields produce forces that affect the trajectory of the particles of the beam and can potentially destabilize the trajectories.

Extensible: Object oriented coding to make it relatively easy to extend the capabilities.

Space Charge Codes[edit]

The self interaction (e.g. space charge) of the charged particle beam can cause growth of the beam, such as with bunch lengthening, or intrabeam scattering. Additionally, space charge effects may cause instabilities and associated beam loss. Typically, at relatively low energies (roughly for energies where the relativistic gamma factor is less than 10 or so), the Poisson equation is solved at intervals during the tracking using Particle-in-cell algorithms. Space charge effects lessen at higher energies so at higher energies the space charge effects may be modeled using simpler algorithms that are computationally much faster than the algorithms used at lower energies.Codes that handle low energy space charge effects include:

ASTRA ^[7]
Bmad
CST Studio Suite ^[25]
GPT ^[26]
IMPACT ^[27]
mbtrack ^[28]
ORBIT,^[29] PyORBIT^[30]
OPAL ^[31]
PyHEADTAIL ^[32]
Synergia ^[33]
TraceWin ^[34]
Tranft ^[35]
VSim ^[36]
Warp ^[37]

At higher energies, space charge effects include Touschek scattering and coherent synchrotron radiation (CSR). Codes that handle higher energy space charge include:

Bmad
ELEGANT
MaryLie
SAD

Beam-beam effects codes[edit]

When two beams collide, the electro-magnetic field of one beam will then have strong effects on the other one, called beam-beam effects. Ris file opener. Leprechaun games for free. Mail designer pro 3 2 2 download free. Codes for this computation include

GUINEA-PIG^[38]

Impedance computation codes[edit]

An important class of collective effects may be summarized in terms of the beams response to an 'impedance'. An important job is thus the computation of this impedance for the machine. Codes for this computation include

ABCI ^[39]
ACE3P ^[40]
CST Studio Suite ^[41]
GdfidL^[42]
TBCI ^[43]
VSim ^[36]

Magnet and other hardware-modeling codes[edit]

To control the charged particle beam, appropriate electric and magnetic fields must be created. There are software packages to help in the design and understanding of the magnets, RF cavities, and other elements that create these fields. Codes include

ACE3P ^[40]
COMSOL Multiphysics ^[44]
CST Studio Suite ^[45]
OPERA ^[46]
VSim ^[36]

Lattice file format and data interchange issues[edit]

Given the variety of modelling tasks, there is not one common data format that has developed.For describing the layout of an accelerator and the corresponding elements, one uses a so-called 'lattice file'.There have been numerous attempts at unifying the lattice file formats used in different codes. One unification attempt is the Accelerator Markup Language, and the Universal Accelerator Parser.^[47] Another attempt at a unified approach to accelerator codes is the UAL or Universal Accelerator Library.^[48]

The file formats used inMAD may be the most common, with translation routines available to convert to an input form needed for a different code. Associated with the Elegant code is a data format called SDDS, with an associated suite of tools. If one uses a Matlab-based code, such as Accelerator Toolbox, one has available all the tools within Matlab.

Codes in applications of particle accelerators[edit]

There are many applications of particle accelerators. For example, two important applications are elementary particle physics and synchrotron radiation production. When performing a modeling task for any accelerator operation, the results of charged particle beam dynamics simulations must feed into the associated application. Thus, for a full simulation, one must include the codes in associated applications. For particle physics, the simulation may be continued in a detector with a code such as Geant4.

For a synchrotron radiation facility, for example, the electron beam produces an x-ray beam that then travels down a beamline before reaching the experiment. Thus, the electron beam modeling software must interface with the x-ray optics modelling software such as SRW,^[49] Shadow,^[50] McXTrace,^[51] or Spectra.^[52] Bmad^[9] can model both X-rays and charged particle beams. The x-rays are used in an experiment which may be modeled and analyzed with various software, such as the DAWN science platform.^[53] OCELOT ^[54] also includes both synchrotron radiation calculation and x-ray propagation models.
