Ah! The K'dink effect! When the plate voltage gets high enough, the electrons crash into it so hard that they actually knock atoms loose from the plate. Then, when these atoms from the plate hit the glass envelope, they go, "k'dink!". ;-)

I remember the suppressor grid from my Navy electronics school tube-section final exam. The correct answer is D: all of the above.
There was that and also something about preventing small amounts of residual ionized gas molecules which would then accelerate towards and impact the cathode reducing its working lifetime.
Rich,
Actually, the answer is in your post in another thread, where you mentioned a degausser. The holes in the tubes mentioned in the post are ... degassers!
