Hello, I’ve a positron beam hitting two circular targets having radius 0.75cm
@anna helped me to add the GPS in order to set the beam size, position etc.
/gps/pos/radius 0 cm
Today I was trying to modify the beam size, but it looks like that results don’t change.
For example, this is a correlation plot between the released energy and hitpoints in the first target setting radius of the beam 0 cm
and this is the same plot setting the radius 0.75cm (ie. the same radius of the target)
/gps/pos/radius 75 mm
you see I get the same plots.
Should I change something else ?
This is the code
EDIT: Today I canged the beam typology setting Gaussian beam instead of Mono Energetic and I nociced differences between the results got by the two beams, I thinkt that it means that the GPS function works…so it’s strange that results don’t change enlarging the beam size.
Does anyone know how to solve?
