5.3.12. Cone source

The parameters for the cone source are shown below. In this case, source particles are generated on the side surface of the cone. The order of parameters is free. Parameters with (D=***) are optional.

value	explanation
(D=0.0)	y coordinate of the top of the cone [cm].

Table 5.3.122 z0

value	explanation
(D=0.0)	z coordinate of the top of the cone [cm].

Table 5.3.123 x1

value	explanation
(D=0.0)	x component of the vector from the top to the center of the bottom circle [cm].

value	explanation
mono-energy source	Give the source energy [MeV/n] directly by e0.
energy spectrum	Specify the source energy distribution by e-type.
