|Disassembled Penning gauge. It was filthy with plated material and loose shiny black sand-like material. Sanded anode and cathode cups to remove the bulk of plated material. Removed ion trap and sanded interior metal surfaces. (The plastic surfaces are filthy, but I don't know how to clean this.) Cleaned all metal parts in 3 progressive changes of acetone in an ultrasonic bath. Anode wire was bent in re-insertion. Following re-assembly, pressure was 1.5e-4 torr. | |||
