Particles

1. Locate the Particles option and choose between Add GEO Electron or Particle Source.

   

    

2. A properties menu will appear along with the Particle Source within the structure tree.

   

    

3. The following tables contain information on the possible parameters for General, Geometry Options, and Energy Spectrum. What is included in each subsection is determined by the Particle Type and Spectrum Type. The Particle Type can change the parameters in General, while Spectrum Type changes the parameters in Energy Spectrum. To see a full list of options for each access the drop down menu in the properties interface.

    

4. General

   Entry	Meaning
   Number of Particles	Enter the number of particles used per time step used for the Particle Tracking feature
   Number of Time Steps	The number of time steps the source will be active, with the time step length defined in the Domain
   Atomic Number	Set the atomic number for the Ion particle source
   Nucleon Number	Set the nucleon number for the Ion particle source
   Charge [e]	Set the charge value for the Ion particle source
   Nuclear Excitation [MeV]	Set the nuclear excitation for the Ion particle source

    

5. Geometry Options

   Source Geometry	Parameters
   Boxed	Allowing for mono or bi-directionality along X, Y or Z axis: + X, Y, Z- True enables flux in direction, False disables - X, Y, Z- True enables flux in direction, False disables
   Cylindrical	Plane- Select the plane the source will be normal to: Divisions- set the number of divisions to use for the cylindrical source
   Spherical	Incidence Type- Select either focused or Isotropic: Isotropic- Particles travel in all directions Focused- Particles travel radially towards origin
   Planar	Plane- Select the plane the source will be normal to Direction- select either the + or - direction in the plane axis chosen
   Charge Density	Set the Ion charge density

    

6. Energy Spectrum

   Entry	Meaning
   Spectrum	Import spectrum file
   Current [A/m2]	Set the current that will be used for a single time step in the spectrum file
   Energy Spectrum	Set energy levels and the corrisponding fluence
   Integral Flux Time [s]	Time adjustment made to the manual entry of energy bins
   Spectrum Energy [MeV]	Set the energy that will be used for a single time step in the spectrum file
   Satellite Name	Satellite to be imported from SKT
   SKT Particle Source	Generate Particle Source from SKT data
   In Sync	Has particle source been synced with SKT
