[Gate-users] Exponentiel Energy distribution

[ESLAM TAHA]

Hi,

This is an example for an exponential energy distribution source:

/gate/source/addSource  SOURCE_NAME

/gate/source/SOURCE_NAME/gps/particle   geantino

/gate/source/SOURCE_NAME/gps/pos/type   Plane

/gate/source/SOURCE_NAME/gps/pos/shape   Annulus

/gate/source/SOURCE_NAME/gps/pos/radius   3. cm

/gate/source/SOURCE_NAME/gps/pos/inner_radius   1. cm

/gate/source/SOURCE_NAME/gps/pos/centre   0.5 1. 0. cm

/gate/source/SOURCE_NAME/gps/ang/type   cos

/gate/source/SOURCE_NAME/gps/ene/type   Exp

/gate/source/SOURCE_NAME/gps/ene/min   2. MeV

/gate/source/SOURCE_NAME/gps/ene/max   10. MeV

/gate/source/SOURCE_NAME/gps/ene/ezero   2.


I hope this helps.


My regards,

Eslam
