 \section B2_s4 PRIMARY GENERATOR
 
    The primary generator action class employs the G4ParticleGun.
-   The primary kinematics consists of a single particle which starts at the world boundary
-   and hits the target perpendicular to the entrance face. The type of the particle
-   and its energy can be changed via the G4 built-in commands of
-   the G4ParticleGun class.
-   Note that this particular case of starting a primary particle on the world boundary
-   requires shooting in a direction towards inside the world.
+   The primary kinematics consists of a single particle which starts close

  4- PRIMARY GENERATOR
 
      The primary generator action class employs the G4ParticleGun.
-     The primary kinematics consists of a single particle which starts at the world boundary
-     and hits the target perpendicular to the entrance face. The type of the particle
-     and its energy can be changed via the G4 built-in commands of
-     the G4ParticleGun class.
