Question cut in range too big for material 

Forum: Physics List
Date: 22 Aug, 2008
From: Giulia De Bonis <Giulia De Bonis>

Dear all,
Here a short description of my application:
My primaries are 100 MeV proton beam, collimated passing through a hole in a lead screen and entering a water tank. The exerimental hall is a box filled with vacuum.

MyDetPhysicsList is exactly the same as ExN03PhysicsList, and the run-macro sets the same verbosity of example/novice/N03/run1.mac

Running my application I experience several of the following:

G4VRangeToEnergyConverter::ConvertCutToKineticEnergy for gamma
The cut in range [1 (mm)] is too big for material idx=5
The cut in energy is set1.79769e+305GeV


The strange fact is that problems appear to occur in material with index idx=5, but there is no such a material, since I defined three materials only, and the Material-Cuts Couples seem to well behave.

Do I have to worry about this?

In attachments, the complete output file.

I am looking forward for suggestions and advices

Giulia
