[Gate-users] To set an energy threshold limit lower than 250 eV

[David Sarrut]

Hello,

exact, the lower limit was hardcoded I dont really know why. You can try to
set it to 0 or 100 eV in the source code to see what happens. It may slow
down simulation. Note this is a "production cut" not a "range cut" (lower
limit for the G4ProductionCutsTable)

Maybe it could be interesting to allow the user to set this value by a
macro ...

Sincerely,
David
