Creating Lead Cylinder
For a lead cylinder with outer radius of 60mm, to ensure Moller electrons can clear the material:
Since the Geant4 solid is based on it's half-distance with respect to the origin, we need to add 6000 to this to find the starting distance.
Geometry files follow the format:
Name: No Spaces Mother: root if primary component Description: Short explaination Position: The center of the object wrt to the vertex Rotation:0*deg 0*deg 0*deg Type: G4 Tube Dimensions: Inner Radius, Outer Radius, Half-Length in z, starting phi position angle of segment ,delta phi angle of segment Material: Defined in materials file Color:The color entry is a 6 digit hexadecimal number that represents Red, Green and Blue weights from 0 to 255 each in the form: RRGGBB Visible: 1=Yes, 0=No Style:1=Solid,0=Wireframe
