Can COMSOL give me the focal point of a beam of particles?

Hi,

I am modelling this einzel lens to focus a beam of charged particles using the particle tracing module.

Is there a way to make COMSOL tell me the coordinates, at which I have my focal point?
Or better, just give me a table of values with radius and coordinate of my beam?

If yes, I would be greatful to learn how, as I am still rather new using this module of COMSOL. :-)

Thanks anyway,

If this cannot be done easily, I was thinking that maybe you can chose one of the particles and extract a table with its coordinates. Then I could easily find it with a little extra work. Is this possible?
I haven't tried it, since my license only works at the university.
