Or with penning / pirani gauges make sure you have a right angle bend between chamber and gaugehead
so the gauge does not see the plasma
ions are like rays of light they do not go round corners

To make my screen, I cut a small, circular piece of copper screen (but larger than the hole it is intended to fit "over") and gently pressed that piece of screen into said hole (making good electrical contact with the metal walls of the gauge tubes.) Works very well and solved the issue without causing any gauge reading errors since it is a fine, but not supper fine mesh. While a right angle is a good idea, that would require (for me) more KF connectors so, I went the simple, cheap, and easy method (not unlike most my designs ...lol.)
