Hello
for electromagnetic particles, low energies, thin layers..
you can
Reduce the average step size to something like 5% through the EMFFIX card,
And activate single scattering through MULSOPT, sdum=GLOBEMF. with this
card, sigle scattering can be activated only near to boundaries, or for
all transport. steps.
Single scattering everywhere is the most precise option, but of course it
is very time-consuming.
Have a nice day
