Dear Liu, Yong,

I don't know what could be wrong with your installation. exampleN06 should produce Cerenkov photons. However, 9.5.0 has serious problems when it comes to optical photon tracking. The time is not correctly updated (see another post on this Forum):

http://hypernews.slac.stanford.edu/HyperNews/geant4/get/opticalphotons/420/1.html

and also we suspect that the surface normal is not always calculated correctly in cases where the volume is rotated with respect to its mother volume - this suspicion has yet to be confirmed, however!

Therefore, I adivse you and all users of optical photon tracking in G4 to NOT update to 9.5 at this time. The latest working version is 9.4.p03.

Peter
