Photomultiplier
Creation of secondaries, specular reflection.
This example illustrates how a secondary ray can be created when a ray hits an electrode.
The option enables photomultipliers to be simulated.
Here the secondary ray has the same energy as the primary ray and is specularly reflected, but
many other options are available.
