Can I define the point and disk sources? These are not explicitly offered in Angle source options.
Yes. For disc sources just enter zero for the source height. For point sources enter zero both for height and radius. You may notice that Angle will perform the calculations much faster in these cases, than for a cylindrical or Marinelli source.
Do I need to know the composition of the material of my source?
Yes (except if you are using point or disk sources). It is very important to know as well as possible the materials of your whole configuration (including the source, its container, detector construction details, absorbing layers etc.), because it is an essential parameter for the calculation of gamma-ray attenuations (self-attenuation in case of source).
My source is “self-standing”, in form of a solid pill, i.e. I do not need a container to place it in. Can Angle handle this situation?
Yes. Simply select the “No container” option in Angle.
My source is in the form of a solid pill placed in a container – the pill radius is smaller than the container inside radius. Can Angle handle this situation?
Yes. Simply click the “Source radius” option in the “Source” group of the main window and enter the value you want. This radius, of course, cannot be greater that the container’s inside radius.
I am studying the properties of some spherical coated sources. Does Angle support that?
No, Angle does not support spherical sources. Nevertheless, if there is an explicit user’s request to do this, such an option can be considered/developed.
I am counting cylindrical sources positioned perpendicularly to the detector axis. Can I use Angle to calculate detection efficiency?
No, Angle does not support cylindrical sources positioned perpendicularly to the detector axis. Nevertheless, if there is an explicit user’s request to do this, such an option can be considered/developed.
