Question Need help implementing a radial electric field 

Keywords: radial electric field
Forum: Fields: Magnetic and Otherwise

From: Andrew Dummer <Andrew Dummer>

I am interested in simulating a Geiger-Mueller Tube but that means that I need to implement a radial electric field. All I can find are discussions of uniform electric fields. Mine is a nonuniform field. The solution for the electric field within the detector is easily determined to be:

E(r)=V/(r*ln(b/a))

Where V is the voltage applied, b and a are the inner radius of the tube and the outer radius of the anode wire respectively. What is not at all obvious to me is how to implement this within the constructs of GEANT4. Are there any good examples of something like this? Can anyone give me some pointers?

Thanks.
