Re: Source Geometry

Hello Patrick,

With the BEAM card you can define an annular spot with inner radius and
outer radius, if you set WHAT(6) < 0.0 (see manual at BEAM section), but
if you want to describe a cylindrical source you have to use "source.f"
routine modified in your own way.
See Anna Ferrari's answer yesterday in the list for example or older
mails on this topic in the list. How to define a cylindrical source is
widely discussed.
Hope it helps.
Regards.

Sebastien.
