Dear All, I've posted this problem on the user forum but thought it may be a good idea to submit it formally. I have a stripped down, simple simulation to provide anyone who is willing to reproduce the problem. The simulation is a cube of silicon, transporting gamma photons of 100 keV. A default cut of 1 m is used, yet secondary electrons are produced in compton interactions. Note this is after issueing the SetApplyCuts(true,"all") method in the SetCuts method of the PhysicsList. I've also tried it using the /run/particle/applyCuts true all command and I run into the same problem. Details of my computing environment are as follows: inux-2.6.11.4-21.7 suse OS gcc version 3.3.5 20050117 (prerelease) (SUSE Linux) Please contact me and I will email a tar.gz file containing the simulation. Thank you and I look forward to a response. Best Regards, Iwan Cornelius Postdoctoral Research Fellow, Centre for Medical Radiation Physics, University of Wollongong, Australia.

This is not a bug. Secondaries may be created if ApplyCuts flag is true and production cut values are large. In section 5.4.3 of User's Guide: For Toolkit Developers >ApplyCut in ON: the TrackingManager checks the range of each secondary >against the production threshold and against the safety. The particle >is stacked if range > min(cut,safety). It means that secondaries produced at the point close to the volume boundary may survive because the current range is bigger than safety (roughly speaking, safety is distance to the nearest boundary )
