This program simulates scattering caused by charged particles. It is possible to observe the paths of various particles simultaneosly and change all problem parameters: speed and position of projectiles, charge and number of deflecting particles, etc .

Instructions:

• Press Start and the program will run. It stops with Pause. Returns to initial configuration with Stop. Every time that you want to change parameters you must press Start again.
  
• You can choose from different scattering pre-established situations in the pop-up list.
  
• Initial, Distant, Particles and Veloc. are useful to change projectiles.
  • Initial is an integer that indicates the position (in pixels) of the first projectile from the upper border.
  • Distant is the distance (in pixels) between two consecutive projectiles, it must be a integer.
  • Particles is the number of particles.
  • Veloc. is the velocity of all the projectiles, it is a floating point value.
  • dt is a floating point value that is related with the error; generally it is not necessary to changed it.
    
• Remove erases all the particles.
  
• If you want to add particles, choose: Electron (negative) or Proton, (positive) then press Add and click the mouse in the place where you add the particle.
  
• You can see the values of the parameters by pressing Data.
