Question How to set the cut value in energy? 

Keywords: cut value in energy run time

Hi friends:

I understand that the cutoff value is set in range and G4ParicleWithCuts() class provides
the functionality to convert the cut value in range into energy threshold.

In order to set the cut value in energy, I have some questions as follows:

1. I want to set directly the energy cutoff of photons and electrons to 10 KeV and 500 KeV,
respectively. In the other hands, I know how to set the cut value in range by using SetCuts()
and SetRangeCut(), but I do not know how to set the cut value in energy?

2. Is the energy cutoff reduced the run time of my simulation effectively?

3. Can I set different cut value in energy for each physical volume? How can I do it?

Please help me.
Thanks a lot.
