Hello; Maybe this trick will work for you. I had the same problem, using a planar ParticleGunSource from a macro file, it worked only on a given axis, i think 0 0 1. I could only debug this situation by launching some neutrons with a viewer. Try with a very thin volume: /gps/pos/type Volume /gps/pos/shape Para /gps/pos/centre 0. -45 0. mm /gps/pos/halfx 45 mm /gps/pos/halfy 0.001 mm /gps/pos/halfz 60 mm /gps/direction 0 1 0 Worked fine for me.
