Hello,

There are two possibilities: 
  - bug in your geometry - your particle does not see some Si layers; 
  - specific of thefluctuation model - there is a probability to have zero energy deposition in thin Si due to fluctuations of energy loss.

To figure out what happens one can to run small statistic with "/tracking/verbose 1" - the particle trajectory and the step lengths will be seen.

Also, it is possible to create a histogram - energy deposition per layer, if everything is correct, then mean energy per layer should be smooth.

Likely this question should be in emprocess forum, not in geometry one.
