Hi Dieter, do You have more information about "sputtering windows"? I hear it for the first time. I know that any hole significantly bigger then anode screen holes let the sputtered particles to go through and deposit on the glass (ZM1040/42 have small "window"), but I dont know whether it has any real effect on lifetime of the nixie. Apart from that it allows You to estimate (roughly) its age..
Can You compare deposit of mercury doped IN-18 and non-doped IN-18 after years of usage?
