Question what is the meanning of parameters in the SetParticleMomentumDirection() 

Keywords: beam direction

Hi all!

In my source file, I want to generate the cone beam into the z axis.

My questions are

1) In order to make cone beam, Which class do I use in the myPrimaryGeneratorAction.cc?

2) As I mentioned in the title, If the SetParticleMomentumDirection() function was usually used in order to generate the beam into the special direction, what is the meannig of the parameter in the function? Is the parameter directed cosine?

3) If there is another method to generate the cone beam, Could you show me that how to modify my input file?

4) I do not understand the funcion,GeneretePrimaryVertex(),, Could you give me more information about the meanning of this function?

regards H.D.Kim
