Hello:

I would like to include a diagram for my presentation showing a thermionic cloud. I've looked on the computer for something to get me started and have come to a dead end. Does anyone know where I can look to get some ideas of what a thermionic cloud looks like?

My understanding is that it is a cloud of negatively charged electrons around the cathode (negative) end.

Thank you

Welcome to Physics Forums.

I suggest a google image search.

Just type thermionic cloud in the search box. Several ways of representing the electrons come up among the choices.

Thermionic space charge is another good search phrase.
