xmpl3d48, 48th 'example' data file for CPO3D



A primitive photomultiplier.  For a quick demonstration, the number of cathode rays is small and they do not cover the cathode surface.


No attempt has been made to optimise the behaviour, since the purpose of this example is only to demonstrate the option to create secondary rays.


This example illustrates how a secondary ray can be created when a ray hits an electrode.


Here the secondary rays are emitted normal to the electrode, with a fixed energy of 1eV, when the primary energy is 10eV or higher, but  many other options  are available.

Space-charge iterations are not carried out in this example.
