Hi Brian,

I can see nothing wrong with your code snippet. Unfortunately, the G4 developer who can best assist you with your problem is going 'off line' for some weeks summer vacation, starting today. One suggestion, what happens when you change:

fIntgrDriver = new G4MagInt_Driver(1.0*micrometer, fStepper, fStepper->GetNumberOfVariables(), 2);

the 1.0*micrometer to some larger value?

I have also noticed that none of our 'official examples' use G4ExactHelixStepper.

What about if you used the method:

fieldMgr->CreateChordFinder(fMagField);

instead?

This seems to be using G4ClassicalRK4 even for constant magn. fields.
